Touch Probe Systems for Machine Tools
Touch probes from H EID EN H AIN w ere
conceived for use on m achine toolsin
particular m illing m achines and m achining
centers. Touch probes help to reduce setup
tim es, increase m achine usage tim e and
im prove the dim ensional accuracy of the
nished w orkpieces. Setup, m easuring and
m onitoring functions can be perform ed
m anually orin conjunction w ith m ost
CN C controlsunder program control.
Workpiece measurementH EID EN H AIN offers TS triggering touchprobesfor w orkpiece m easurem ent righton the m achine. The probe is inserted in
the tool holder either m anually or by the
tool changer. They enable you to use the
probing functions offered by your N C
control to autom atically or m anually
perform the follow ing functions:
W orkpiece alignm ent
W orkpiece presetting
W orkpiece m easurem ent
D igitizing or inspecting 3-D surfaces
Tool measurementSuccessful series production hinges on the
prevention of scrap or rew ork and the
attainm ent of consistently good
w orkm anship. The tool is a decisive factor
here. W ear or tool breakage that go
undetected for extended periods,
especially during unattended operation,
result in defective parts and unnecessarily
increase costs. Therefore, exact
m easurem ent of tool dim ensions and
periodic control of w ear are absolutely
essential. For tool m easurem ent on the
m achine, H EID EN H AIN offers the TT three-
dim ensional touch probe and the TL laser
system s.
W ith the TT triggering touch probes,thecontact plate is defl ected from its rest
position, sending a trigger signal to the N C
control, during probing of the stationary or
rotating tool.
The TL laser systemsoperate w ithout anycontact. A laser beam probes the length,
diam eter or contour of the tool. Special
m easuring cycles in the N C control
evaluate the inform ation.

Application ExamplesW orkpiece A lignm ent
Exact w orkpiece alignm ent parallel to the
axes is particularly im portant for partially
m achined w orkpieces to ensure that
existing datum surfaces are in an
accurately de ned position. W ith the TS
touch probe system s from H EID EN H AIN
you can avoid this tim e consum ing
procedure and do w ithout the clam ping
devices otherw ise required.
The w orkpiece is clam ped in any
position.
The touch probe ascertains the
w orkpiece m isalignm ent by probing a
surface, tw o holes, or tw o studs.
The C N C com pensates for the
m isalignm ent by rotating the coordinate
system . It is also possible to
com pensate for it m echanically by
rotating the table.

Selection Guide
The TS w orkpiece touch probes from
H EID EN H AIN help you perform setup,
m easuring and inspection functions directly
on the m achine tool.
The stylus of a TS touch trigger probe is
defl ected upon contact w ith a w orkpiece
surface. At that m om ent the TS generates
a trigger signal that is transm itted either by
cable or over an infrared beam to the
control. The control sim ultaneously saves
the actual position values as m easured by
the m achine axis encoders, and uses this
inform ation for further processing. The
trigger signal is generated through a w ear-
free optical sw itch that ensures high
reliability.

Principle of FunctionSensor
TS 2xx, TS 44x, TS 64xTouch probes from H EID EN H AIN operate
w ith an optical sw itch as sensor. A lens
system collim ates the light generated from
an LED and focuses it onto a differential
photocell. W hen the stylus is defl ected,
the differential photocell produces a trigger
signal.
The stylus of the TS is rigidly connected to
a plate integrated in the probe housing on a
three-point bearing. The three-point bearing
ensures the physically ideal rest position.
Thanks to the non-contacting optical
sw itch, the sensor is free of w ear. In this
w ay, H EID EN H AIN touch probes ensure
high long-term stability w ith a constantly
probe repeatability even after very m any
m easuring processes, as for exam ple w ith
in-process applications.

TS 740The TS 740 uses a high-precision pressure
sensor. The trigger pulse is obtained through
force analysis. The forces acting during
probing are processed electronically. This
m ethod provides extrem ely hom ogeneous
probing accuracy over 360.
W ith the TS 740, the de fl ection of the stylus
is m easured by several pressure sensors
that are arranged betw een the contact
plate and the probe housing. W hen probing
a w orkpiece, the stylus is defl ected so that
a force acts on the sensors. The signals
generated are processed and the trigger
signal is produced. The relatively low probing
forces provide high probing accuracy and
repeatability, w hile offering precise trigger
characteristics in all directions.

Probe repeatabilityProbe repeatability is the dispersion of the
results derived from repeated probing
from the same direction.
Influence of probe styliStylus length and stylus m aterial directly

touch probe. Styli from H EID EN H AIN
ensure a probing accuracy grade of better
than 5 m .

Probe accuracyThe probe accuracy speci es the error
resulting from probing a test com ponent
from various directionsat 22 C am bienttem perature.
The probing accuracy also includes the
effective ball radius. The effective ball radius
is calculated from the actual ball radius and
the stylus de fl ection required to produce
the trigger signal. This also includes stylus
bending.
Touch probes are m easured for accuracy
on precision m easuring m achines at the
H EID EN H AIN plant.
The TS 740triggering touch probe ischaracterized particularly by high probing
accuracy and repeatability. These features,
together w ith its low probing force, m ake
the TS 740 suitable for very dem anding
m easuring tasks on m achine tools.

Signal Transm ission
TS 220, TS 230, TS 249Touch Probes with Signal
Transmission by Cable
For these touch probes, both the pow er
supply and the trigger signal are conducted
over the touch probe's cable.
The m achine operator inserts the TS 220,
TS 230 touch probes by hand into the
spindle. The spindle m ust be locked before
the touch probe can be inserted (spindle
stop). The CN C's probing cycles can run
w ith both vertical and horizontal spindles.
Pow er supply
Trigger signal
TS 44x, TS 64x, TS 740Touch Probes with InfraredTransmission of the TriggerSignal
The TS 44x, TS 64x and TS 740 touch
probes transm it the trigger signal through
an infrared light beam . This m akes them
ideal for use on m achines w ith autom atic
tool changers.
Infrared beamThe infrared transm ission is established
betw een the touch probe and the SEtransm itter/receiver unit. The follow ing
transceivers are available:
SE 540 for integration in the spindlehead
SE 640 for integration in the m achine'sw orkspace
SE 642 as com m on SE for w orkpieceand tool touch probes
They can be used in any com bination w ith
the TS 44x, TS 64x and TS 740.
The infrared transm ission is tolerant to
noise and even w orks by refl ection. It
therefore covers a very broad range ofapplications. For exam ple, the TS 64x can
be used both in vertical and horizontal
spindles as w ell as in sw ivel heads. An
even greater infrared transm ission range
can be realized by com bining tw o SE 640s
through an A PE 642 interface unit.
The infrared beam transm its several
signals: The start signalactivates thetouch probe. W ith the ready signalthetouch probe indicates that it is ready for
operation. A defl ection of the stylus
produces the trigger signal.If the TS 64x/
TS 740's battery capacity falls below 10 % ,it transm its a battery warning.The fallingedge of the start signal sw itches the touch
probe off again.

Infrared Transm ission Range
Transmission areaThe transm ission areas betw een the S E
transm itter/receiver unit and the touch
probes have a lobe form . In order to ensure
an optim um signal transm ission in both
directions, the transceiver should be
m ounted so that the touch probe is w ithin
this range during all operation positions. If
the infrared transm ission is disturbed or
the signal becom es too w eak, the SE
noti es the CN C through the ready signal.
The size of the transm ission range
depends on both the touch probe and the
transceiver used w ith it.

Transm itter/Receiver U nit
The S E transceiver is to be m ounted so
that it rem ains w ithin the transm ission
range of the touch probe over the
m achine's entire range of traverse.
SE 540 transmitter/receiver unitThe S E 540 is intended for integration in
the spindle head. Except for a few cases,
for exam ple on m achines w ith quills, this
ensures transm ission on m achines w ith
very large traverse ranges or w ith sw ivel
heads. The transm ission range of the
infrared signal is appropriate to the
m ounting location. Because the SE 540 is
alw ays above and to the side of the TS,
H EID EN H AIN recom m ends using touch
probes w ith +30 transm ission angle. The
m achine m ust be designed to support the
SE 540.
SE 640, SE 642 transmitter/receiver unitThe S E 64x is m ounted at a suitable
location in the m achines w orkspace. It is

IP 67 degree of protection, it can also
tolerate coolant. A holder to facilitatem ounting is available as an accessory.
W hen m ounting the SE 642 it is im portant
to note that it can com m unicate both w ith
the TS w orkpiece touch probe and w ith the
TT 449 tool touch probe. The touch probes
very large angular range of transm ission
(up to 7 m w ith the TS 640) allow s reliable
transm ission to m achines w ith long axes.
For special applications, for exam ple very
large m achines, the transm ission range can
be enlarged by installing a second SE 640.
The connected APE 642 interface electronics
unit evaluates the infrared signals so thatthe N C receives only one trigger signal
regardless of the w orking range in w hich
the touch probe is located.

Selection Guide
Tool m easurem ent on the m achine
shortens non-productive tim es, increases
m achining accuracy and reduces scrapping
and rew orking of m achined parts. W ith the
tactile TT touch probes and the contact-free
TL laser system s, H EID EN H AIN offers tw o
com pletely different possibilities for tool
m easurem ent.
W ith their rugged design and high degree
of protection, these tool touch probes can
be installed directly w ithin the m achine
tool's w ork envelope.
TT touch probesThe TT 140 and TT 449 tool touch probes are
touch trigger probes for the m easurem ent
and inspection of tools. The TT 140 features
signal transm ission by cable, w hile the
TT 449 com m unicates w irelessly over an
infrared beam w ith the SE 642 transm itter/
receiver unit.
The disk-shaped probe contact of the TT is
defl ected during physical probing of a tool.
At that m om ent the TT generates a trigger
signal that is transm itted to the control,
w here it is processed further. The trigger
signal is generated through a w ear-free
optical sw itch that ensures high reliability.
The probe contact is easy to exchange. The
connection pin to the touch probes contact
plate features a rated break point. This
protects the touch probe from physical
dam age due to operator error.
TL laser systemsThe TL M icro and TL N ano laser system s
can m easure tools at the rated speed
w ithout m aking contact. W ith the aid of the
included m easuring cycles you can
m easure tool lengths and diam eters,
inspect the form of the individual teeth and
check for tool w ear or breakage. The
control autom atically saves the results of
m easurem ent in the tool table.
The m easurem ent is very fast and
uncom plicated. U nder program control, the
N C control positions the tool and starts the
m easuring cycle. This is alw ays possible:
before m achining, betw een tw o m achining
steps, or after m achining is done.
The axially focused laser beam m easures
tools as sm all as 0.03 m m in diam eter at a
repeatability of up to 0.2 m .

TT Touch Probes for Tool Measurement
Together w ith the m easuring cycles of the
CN C control, the TT tool touch probes
enable the TN C to m easure tools
autom atically w hile they are in the m achine
spindle. The control saves the values
m easured for tool length and radius in the
central tool le. By inspecting the tool
during m achining you can quickly and
directly m easure w ear or breakage to
prevent scrap or rew ork. If the m easured
deviations lie outside the tolerances, or if
the m onitored life of the tool is exceeded,
the control can lock the tool or
autom atically insert a replacem ent tool.
W ith the TT 449, all signals are transm ittedto the control via infrared beam .
Advantages:
G reatly increased m obility
Fast installation at any location
U se also on rotary and tilting axes
Your benefit:W ith the TT 140 or TT 449tool touch probe you can have your CN C
m achine operate unattended w ithout losing
accuracy or increasing scrap rates.
7/26/2019 heidenhain Touch Probe

Principle of Function
SensorTouch probes from H EID EN H AIN operate
w ith an optical sw itch as sensor. A lens
system collim ates the light generated from
an LED and focuses it onto a differential
photocell. W hen the probe contact is
defl ected, the differential photocell produces
a trigger signal. The probe contact of the TT
is rigidly connected to a plate integrated in
the probe housing on a three-point bearing.
The three-point bearing ensures the
physically ideal rest position.
W ith its contact-free optical sw itch, the
sensor operates w ithout w ear to guarantee
the high long-term stability of H EID EN H AIN
touch probes.
RepeatabilityFor w orkpiece m easurem ent, the
reproducibility of the probing process is of
m ajor im portance. The probe repeatability
speci es the error resulting from repeatedly
probing a tool from one direction at 20 C
am bient tem perature.
The probing accuracy of a touch probe is
m easured at H EID EN H AIN on precision
m easuring m achines.

probing from one direction.

M ounting
The tool touch probes feature IP 67
protection and can therefore be xed
w ithin the w orking space of the m achine.
The TT is m ounted w ith tw o xing clam ps
or on an accessory space-saving m ounting
base.
The TT w ith 40-m m probe contact should
be operated vertically to ensure reliable
probing and optim um protection against
contam ination. Like the cuboid probe
contact, the 25 m m diam eter SC02 probe
contact can also be operated w hen
m ounted in a horizontal position.
D uring w orkpiece m achining, the TT m ust
be sw itched off to ensure that the vibrations
that accom pany norm al m achining do not
trigger a probe signal and cause an
interruption. The w orking space of the
m achine tool should be lim ited in order to
prevent collision w ith the tool touch probe
during m achining.

Probing
The hardened probe contact of the TT tool
touch probe perm its direct probing of the
tool as it rotates opposite to the cutting
direction. Speeds of up to 1 000 m in1 are
perm issible depending on the tool diam eter.
The probe contact is quickly exchanged:
it is sim ply screw ed onto the touch probe
through a t.
The m axim um perm issible de fl ection of
the probe contact is 5 m m in any direction.
The m achine m ust stop m oving w ithin this
distance.
The probe contact of the TT features a
rated break pointin order to protect thetouch probe from physical dam age due to
operator error. The rated break point is
effective in all probing directions. A rubber
sleeve offers protection from splinters.
A defective connection pin can easily be
replaced w ithout requiring readjustm ent of
the TT.
Optical deflection displayTw o LED s on the TT 140 additionally
indicate de fl ection of the probe contact.
O n the TT 449, the condition of the touch
probes is visible through LED s on the
SE 642 transm itter/receiver unit. This is
especially useful for testing correct
operation. You can see at a glance w hether
the TT is currently defl ected.
Probe contactsTo probe milling cutters, the tool touchprobes are equipped w ith a disk-shaped
probe contact w ith 40 m m diam eter
(exam ple). A disk-shaped probe contact
w ith a 25 m m diam eter is available as an
accessory. Because of its sm all w eight, it
is particularly recom m ended for horizontal
m ounting of the TT.
The TT tool touch probe can also be used
to calibrate lathe tools(exam ple). The atsurfaces of a cuboid probe contact
(available as an accessory) are contacted
by the edges of the lathe tool. This m akes
it possible to regularly inspect tools in N C
controlled lathes for breakage and w ear in
order to ensure process reliability.
The probe contacts can be ordered
separately for replacem ent. The can be
easily replaced, w ithout requiring
readjustm ent of the TT.

w ithout collision. Even the m ost sensitive
tools are com pletely secure from dam age.
The precise determ ination of the length
and radius at the rated shaft speed ensures
your high quality of production. At the
sam e tim e this integrated tool setting w ith
autom atic updating of tool data elim inates
the need for separate tool setting, reducing
costs and non-productive tim es.
Tool m onitoring occurs at the rated shaft
speed in the real clam ping system , and as
such under real operating conditions. Errors
on the tool, spindle and holder can be
im m ediately detected and corrected. Every
single tooth is m easured at the highest
speed. Even the geom etry of special tools
can autom atically be checked on the
m achine for deviations.
Laser Systems for Tool Measurement
The continual process inspection w ith
m onitoring of the tool data detects w ear,
tooth breakage and tool breakage before
dam age occurs. This ensures consistent
production quality, avoids subsequent
dam age, and reduces the cost of scrapped
or rew orked parts. The m easuring cycles
operate autom atically, ensuring optim um
m onitoring even during unattended
operation.
The TL laser system s guarantee reliable
tool m onitoring, high m easuring accuracy
and precise inspection for w ear and tear.
They offer the follow ing bene ts:
Reduced non-productive tim es
U nattended operation
Less scrap
Increased productivity
Consistently high quality of production

Mounting attitudeThe TL laser system s ful ll the
requirem ents for IP 68 and can therefore
be xed directly in the m achines w orking
space. For sm ooth operation, even w ith
coolant and chips, the transm itter and
receiver feature a pneum atically activated
sealing system . The additional introduction
of sealing air provides a very high degree
of protection against contam ination.
The TL laser system s can be m ounted in
both upright and resting positions on or
next to the m achine table. They m ust be
m ounted in a stable enough m anner to
guarantee high repeatability. The cutting
edge should rotate in the appropriate
direction for avoiding bothersom e refl ections
and refractions during m easurem ent by
the laser beam .
The w orking space of the m achine tool
should be lim ited in order to prevent
collision w ith the laser system during
m achining.
Adjusting the TLIn order to achieve the best possible
repeatability, the laser system m ust be
m ounted exactly parallel to tw o N C axes.
For upright m ounting on the m achine table,
the horizontal alignm ent is ensured by the
m ounting surface. The m ounting tolerances
are included in the dim ension draw ings.
D eviations in the parallelism are particularly
noticeable as linear errors w hen m easuring
the length of very different tool diam eters.
It is therefore recom m ended that the
length of eccentric tools (e.g. end m ills,
face-m illing cutters) be m easured on the
outside radius outside of the tool axis.

Protection from Contam ination
The application of laser system s directly on
m achine tools requires effective m easures
to protect the sensitive optical system of
the laser light barrier.
Mechanical protectionThe optics of the laser system s are
perfectly sealed against coolant and chips
by contam ination shutters w ith an
integrated m echanical seal system . The
seal releases the optical system only for
the duration of the m easurem ent. The seal
is actuated pneum atically by the DA 301 TL
com pressed air unit.
Sealing airThe transm itter and receiver of the laser
light barrier are protected by very clean
sealing air from the DA 301 TL com pressed
air unit. It prevents contam ination of the
optical system by coolant spray.

The TL laser system s operate as high-
precision light barriers w ithout any contact.
A laser light source (protection class 2 as
per IEC 825) em its a laser beam . The
opposing receiver unit detects the laser
beam and so captures every interruption.
For any change in statussuch as w hen a
tool interrupts the laser beam or is
rem oved againthe integral electronics
generate a trigger pulse for a de ned
duration. This dynam ic signal DYN is
transm itted to the N C control, w here it is
used for capturing the position value. In
addition, the laser system outputs the
static signal STA for the duration that the
laser beam is interrupted.
CalibratingBefore m easurem ent w ith the TL laser
system can be started, the system m ust
be calibrated, m eaning that the exact
position of the trigger points relative to the
m achine coordinate system m ust be
determ ined. A reference tool, available as
an accessory, is used for this purpose. It
has a characteristic shape for calibration,
w ith a cylindrical dow el pin and a stepped
inspection diam eter for m easurem ent in
the positive and negative Z axis directions
(for determ ining the exact position of the
center of the laser beam in Z). The
reference tool is clam ped into the tool
holder, and its length, diam eter and height
are m easured very exactly. A cylindrical
dow el pin suf ces for sim ple applications.
The best possible runout is to be ensured
for the calibration m easurem ent.

The pulling m easurem ent ensures a high
degree of protection against the infl uence
of coolant and sw arf, w hile the pushingm easurem ent is the better m ethod for

Operating modesThe operating m ode of the laser system is
de ned over the receiver-enabling inputs 1
and 2 (EN ABLE 1/EN ABLE 2). The m easuring
signals autom atically put the receiver in the
appropriate operating m ode.
D uring inspection of individual teeth,each available tooth generates an output
pulse of de ned duration. The pulse length
and the num ber of teeth de ne the basic
speed. In the event of errora m issing
tooth or a tolerance errorthe dynam ic
output signal (DYN ) stays at low level for
m ax. 100 seconds.
In the measuringm ode, every change oflight causes an output signal D YN w ith a
de ned duration of 20 m s. The positive edge
is evaluated. The device is sw itched betw een
pushingand pullingm easurem ent over
the receiver-enabling input 2 (EN ABLE 2).
Optical status indicatorLED s on the receiver side of the laser
system m ake a rapid diagnosis of the
status possible. This w ay the operator sees
at a glance w hether the laser beam path is
O K, w hether a dynam ic trigger signal is
being output, and the current operating
m ode of the laser system .
Probing used toolsThe optically scanning laser system can of
course not distinguish betw een the actual
tool to be m easured and any attached chips,
coolant coating or falling drops of coolant.
In order to avoid faulty m easurem ents, the
tool should therefore be cleaned before
m easuring. This can be done by spinning
off any particles at a high rotational velocity
or by blow ing them off w ith air. The TL laser
system s feature an integral blow ing feature
for this, w hich can be used to clean the
tool before and during a m easuring cycle.

Caution:N ever m ix types or m odels of batteries!
The TS 440, TS 64x, TS 740and TT 449touch probes w ith infrared transm ission
are pow ered by tw o batteries (rechargeable
or nonrechargeable) w ith a rated voltage of
1 to 4 V. The service life depends heavily on
the type and m odel of batteries used (see
table for exam ples). The typical service life
data show n in the speci cations apply only
to the lithium batteries included in delivery.
The touch probe electronics autom atically
detect the type of batteries used. If the
battery capacity falls below 10 % , the SE
transm its a w arning to the control and a
red LED sim ultaneously lights up on the SE.In order to m inim ize the current

TS 444 Energy G eneration through Air Turbine G enerator
The TS 444touch probe w ith infraredtransm ission has an air turbine generator
for pow er generation. Additional
rechargeable or nonrechargeable batteries
are not required.
StructureThe air turbine generator consists of an air
turbine, the actual generator and high-
pow er capacitors for energy storage.
Com pressed air that is supplied through
the spindle is required for operating the
turbine. The com pressed air can also be
used for cleaning the w orkpiece. C harging
the capacitors and cleaning the w orkpiece
are thus com bined in one w ork step. This
elim inates such additional idle tim e.
Principle of functionAfter inserting the TS 444 touch probe, the
high-pow er capacitors are charged by the
air turbine generator. This can be done
w hen the touch probe m oves from the tool
changer to the m easuring position, and
also w hen the w orkpiece is cleaned w ith
com pressed air.
Charging timesThe charging tim es of the capacitors
depend on the available air pressure: The
higher the pressure, the shorter the
charging tim e (see diagram ).
Operating timeW hen the capacitor is fully charged, the
TS 444 is ready for 120 seconds of
continuous operation. The battery w arning
signal reports that the capacitors need to
be recharged.
Requirements for compressed airqualityThe air turbine generator can already
operate at a m inim um pressure of
2 x 105Pa. An operating pressure betw een
5.5 x 105 and 8 x 10 5 Pa is recom m ended
for effective charging. The com pressed air
does not need to be specially cleaned.

Touch Probe with Infrared Transmission
The TS 440, TS 640, TS 740and TT 449touch probes are sw itched on by the C N C
over the SE. The rising edge of the startsignal Ractivates the TS, and the fallingedge sw itches it off.
The TS 642touch probe is activated byinserting it in the spindle by a m icrosw itch
integrated in the taper shank.
The SE uses the ready signal Bto reportto the control that the touch probe is
activated and w ithin the reception area of
the SE. The w orkpiece can now be probed.
The delay t w hen sw itching the probe on or
off depends on the distance betw een the
SE and TS, as w ell as the m ode of the
touch probes pow er supply. Subsequent to
the initial activation (w hen the TS is in
standby m ode) the typical value for
activation is 250 m s, and for deactivation
350 m s (1 000 m s for the m ax. distance).
W hen activating the probe after a longerinterval (m ore than 8 hoursthe TS is in

TL Laser System s, DA 301 TL
TL inputsThe CN C activates the laser system
through three enabling lines:
The transmitter enabling signal 0(EN ABLE 0) activates or deactivates the
transm itter and sw itches the laser beam on
or off. To reduce the pow er loss (heat
generation) to a m inim um and increase
service life, the laser diode is activated only
during the m easuring cycle.
The receiver enabling signals 1and 2(EN ABLE 1 and EN A BLE 2) determ ine the
operating m ode of the laser light barrier
depending on the respective m easuring
cycle.
Signal level:U H = 24 V at 15 m A
TL outputsThe TL laser system s provide the follow ing
output signals:
After the transm itter and receiver are
enabled, the laser system provides the
inform ation Laser OKif the lum inanceat the receiver is at least 75 % of the
m axim um .
Tw o output signals are generated w hen
the laser beam is interrupted. The
measuring signal static STAoutputsw itches to low level if the lum inance at
the receiver is less than 50 %
(= interrupted light beam ).
D o not use this output as trigger signal.
Fast rotating tools cause spike pulses w ith
extrem ely short pulse tim es that cannot be
evaluated by the PLC or N C.
The measuring signal dynamic DYNoutput provides a 24 V pulse w ith a de ned
duration of 20 m s for every light
m odulation (light to dark or dark to light).
This output serves for the trigger signal.

Universal Touch Probe Interface
The U TI 192 converts the output signals
of the H EID EN H A IN touch probe to
m achine control signals in accordance w ith
D IN EN 61 131-2. It supports tw o
H EID EN H AIN touch probes: TT tool touch
probes and TS w orkpiece touch probes.
N ow you can enjoy the bene ts of the
touch trigger probe from H EID EN H AIN
w ith m ost N C controls for m illing
m achines, drilling and boring m achines,
and m achining centers. This is possible
because w ith the new U TI 192 universal
touch probe interface they are also
compatible with all NC controlsw ith afast sw itching input.
O f course, the probing functions actually
available depend on the softw are cycles
im plem ented in the respective N C control.
For certain controls, H EID EN H AIN offersspecial probing cyclesfor autom aticalignm ent and m easurem ent of w orkpieces,
w orkpiece presetting, and tool m easurem ent
(for m ore inform ation:Touch Probe Cycles
for FAN U C ControlsProduct Inform ation).
The U TI 192 features a compact design.It can be quickly fastened on a standard
m ounting rail (D IN 46 227 and EN 50 022) in
the electrical cabinet.
The U TI features a w ide range ofinterfacing possibilitiesso that the touchprobes can easily be connected to the
different NC controls. It is possible, for
exam ple, to con gure the output signals as
active-high or active-low . In addition, it is
possible to connect the inputs or outputs
w ith logical operations. The U TI also
provides various routines for sw itching on
the TS 440 and TS 640 infrared touch
probes.
The U TI 192 is provided w ith LED s for
con guration and easy servicing for initialoperation.The LED s indicate w hetherpow er is on and show the levels of the
inputs and outputs. The selected touch
probe and its status are also displayed.
