WARNING
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Precautions for Correct Use
Do not use the Encoder under ambient conditions that exceed the
ratings.
● Design
Influence of Surrounding Metal
When mounting the Sensor within a metal panel, ensure that the
clearances given in the following table are maintained. Failure to
maintain these distances may cause deterioration in the performance
of the Sensor.

Mutual Interference
When installing Sensors face-to-face or side-by-side, ensure that the
minimum distances given in the following table are maintained.
Mutual interference can be prevented by using the cable length
compensation switch, but doing so will also change coil
characteristics. Specifications such as temperature specifications
and sensing distance, may not be sufficiently met, so always check
operation before actual application.
This method cannot be used for the E2C-G@4A, E2C-JC4A, E2C-
C20MA.

Mounting
• Do not use excessive force when tightening the nuts on the E2C-X
and E2C-C20MA. A washer must be used with the nut.
