Precautions

■ Correct Use

Mounting

With the Roller Lever-type Enclosed Switches, the roller arm has been temporarily tightened prior to shipment, so that its position may be adjusted later. When mounting the Switch, be sure to re-tighten the roller arm so as to prevent it from becoming loose during operation.

To adequately maintain the seals at the mounting screw section on the side of the Enclosed Switch, insert each O-ring correctly and secure it with the lock nut.

To provide the Switch with improved sealing property, use of the SC Connector is recommended.

When routing wires into the conduit opening, be sure that cuttings and other foreign matter do not enter the Switch.

Environmental Precautions

Sealing materials may deteriorate when used outdoors or when exposed to cutting oil, solvents, or chemicals. Check this on actual equipment and, if deterioration is foreseen, consult your OMRON representative in advance.

Be sure to protect part A with grease in order to maintain the mechanical life and performance of the Limit Switch. The use of molybdenum disulfide grease is recommended.

Tightening Torque

A loose screw may result in a malfunction. Be sure to tighten each screw to the proper tightening torque as shown below.

No. Type Torque

1 Cover mounting screw 1.18 to 1.37 N·m 2 Switch mounting screw (see note 1) 1.18 to 1.37 N·m 3 Switch mounting screw (see note 2) 4.90 to 5.88 N·m 4 Switch terminal screw (M4 screws for

head)

5 Roller arm mounting nut 4.90 to 5.88 N·m

Note: 1. This torque range applies to side mounting or bottom

mounting. (M4 screws for head)

2. This torque range applies to side diagonal mounting. (M5

Allen-head bolt)

0.78 to 1.18 N·m

Two, 4.3 dia. mounting holes or M4 screw holes

Side Diagonal Mounting

Two, 5.4 dia. mounting holes or M5 screw holes

Two, 4.3 dia. mounting holes or M4 screw holes

Operation

• Operating method, shape of cam or dog, operating frequency, and

the overtravel (OT) have significant effect on the service life and precision of the Limit Switch. Make sure that the shape of the cam is smooth enough.

• Check that OT has a sufficient margin. The actual OT should be

rated OT x 0.7 to 1.

Dedicated Wrench

The roller arm can be set freely within a range of 225° after loosening the nut.

The roller arm mounting bracket can be set in any direction after loosening the nut.

A dedicated wrench is provided separately. Model: SUPANA FOR ZE Make sure that the nut is free of foreign substances when the nut is

loosened.
