safety of persons either directly or indirectly.

Do not use it for such purposes.

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.

Influence of Surrounding Metal

(Unit: mm)

Note: Values in parentheses for diameter d are the outer diameters of Shielded

Models.

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.

Note: The above values are for a differential travel setting of 5%.

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.

Note: The above leeways in tighten torque assume that a toothed washer is

being used.

• Mounting Unthreaded Cylindrical Models

When using a set screw, tighten it to a torque of 0.2 N·m max.
