Non-shiny Targets

Make sure the sensing side of the sensor is parallel with thesurface of the target object. Do not tilt the sensor towards thetarget object.

Sensing side

Surface of target object

Shiny Targets

If the target object has a glossy surface, incline the sensor by 5#to 10# as shown below, provided that the sensor is not influencedby any background objects.

Glossy object

If there is a mirror--like object below the sensor, the sensor maynot be in stable operation. Tilt the sensor or keep the sensor farenough away from the mirror--like object to avoid interferingreflections as shown below.

J ADJUSTMENTSIf the sensor is not in stable operation due to color differences, make a fine adjustment of the threshold level and confirm that the sensoroperates in stable state. Refer to Manual Teaching (Fine Distance Setting.

Adjustment Steps

1 Install, wire, and turn on the sensor.

2 Perform distance setting (teaching). Refer to Distance Setting (Teaching) below.

3Make a fine adjustment of the threshold, if necessary.Refer to Manual Teaching (Fine Distance Setting)

4 Check that the mode selector is set to RUN.

PrecautionsJ DESIGNINGHigh-voltage LinesDo not place sensor power supply or signal lines within the sameconduit as high-voltage power lines.

Voltage RatingsDo not exceed rated supply voltage, ripple percent (for DCmodels), or load current limits.

Ambient LightingDo not install the sensor in direct sunlight or other sources ofstrong ambient light.

Environmental ConditionsDo not install the sensor in areas

$ With high humidity, or where condensation would result$ With corrosive gas.

$ With high vibration or shock.

Power SupplyIf a switching power supply is used, or when using an inverter orservomotor, you must ground the FG (frame ground) and G(ground) terminals on the power supply for proper operation andto avoid damaging the sensor.

Water ExposureAlthough conforming to IP67, do not use the sensor where it maybe immsersed, is outdoors, or is exposed to rain.To ensure the water resistance of the sensor, tighten the screwsof the operation panel cover to a torque of 0.2 to 0.3 N S m.

Cable$ The bending radius of the cable should be at least 25 mm.

$ When using extended power and signal cable, total lengthmust not exceed 100 m, with a minimum wire size of0.3 mm2 (22 AWG).

$ Do not apply tensile force exceeding 50 N to cable (pre-leaded and connector models).

Avoiding MalfunctionsIf using the photoelectric sensor with an inverter or servomotor,be sure to ground the FG (frame ground) and G (ground)terminals, otherwise the sensor may malfunction.

Proper Mounting ScrewsUse M3 screws and washers to mount the sensor and bracket.

Mechanical ShockAvoid mechanical shock during installation which may amage thehousing (see Shock specifications)

Short--circuit ProtectionIf the load short--circuits, the output will be turned off. Disconnectpower and check the wiring. After correcting the shortedcondition, turn power back on. The sensor will reset theshort-circuit protection function. The short-circuit protection isactivated when the current flow is at least 2.4 times the ratedload current. When using an inductive load, the inrush currentmust not exceed this factor.

Connector$ When connecting or disconnecting the connector, hold the

connector cover to avoid tension on the housoing.$ Tighten the connector by hand only. Do not use tools which

may damage the connector.$ Always disconnect power before connecting or disconnecting

the connector.$ Be sure that the connector is tightened securely. The sesnor

enclosure rating may be reduced or the connector may getloosened.

J MAINTENANCE AND INSPECTIONCleaning$ Solvents damage the casing of the sensor. Do not use

solvents to clean the sensor.

EEPROM Writing Error$ If a teaching data error occurs with the operation indicator

flashing due to a power failure or static noise, perform theteaching operation of the sensor again.
