Tightening Torque

1. Tighten each cover mounting screw to a torque of 1.18 to

1.37 N·m.

2. Tighten each switch terminal screw to a torque of 0.20 to

0.49 N·m if the mounting screw is M3 in size.

Be sure to wire each solderless terminal correctly with a screw as

shown below.

3. Apply a torque of 5.88 to 6.86 N·m to tighten each mounting bolt

of the casing if the mounting bolt is an Allen-head bolt that is M6

in size. Apply a torque of 8.04 to 9.22 N·m instead if the mounting

bolt is an Allen-head bolt that is M8 in size.

Wiring (Ground Terminal Models)

Note: Consult your OMRON representative for details on models with

3 to 6 plungers.

Others

Carefully connect a conduit to each conduit hole and apply a seal or

tape to seal the conduit hole so that cuttings or other materials will

not penetrate through the conduit hole.

Use the SC Connector. Consult your OMRON representative for

details on SC Connectors.

Make sure that the position of the actuator that is traveling does not

exceed the overtravel (OT) position.

Make sure that the operating stroke is 70% to 100% of the specified

OT distance.
