Sample Applications Include:
Our model evolved from our IEC series, the
first slip ring assembly manufactured by our company
over 40 years ago. We have provided thousands of
these units to the oil well logging industry and in the last
10 to 15 years to a number of d i fferent sectors,
inc lud ing the packaging machine indust ry.
The anodized aluminum encasement, gold plated
connector shells and double sealed shaft make it ideal
for inland applications, away from the salt air
environment. This unit mounts cant i levered
at the end of the rotating shaft using the same 2” or 4”
mounting flange as the IEL-BXU.

Our model is designed and manufactured
to withstand the harsh salt water environment found in
oceanographic applications. The passivated stainless
steel encasement, gold plated connector shells and
double sealed shaft give this assembly optimum
resistance against corrosion.The (2 to 44 rings) mounts cantilevered at
the end of the shaft using a 2” or 4” mounting flange.
However, it can be easily modified to mount inside
hoist shaft.

The unit expands the features of the IEL-HS
model, shown on page 9. In the standard configuration
it is designed to fit over shafts up to 8” in diameter and
up to 12” as an option. The standard is
available with 2 to 62 rings or up to an optional 300
rings.The standard bore sizes are: 1, 2, 4, 6 and 8 inches.
If your application requires a nonstandard bore size, we
will build the next larger size and install a reducing
sleeve with the required bore size for a nominal charge.
An example of a modified is illustrated on
page 16, part no. D-1350, model IECFCS-04-58-MOD.
This unit mounts over the shaft of a rotating platform
and transfers power and signals to 7 stations around its
axis.
