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. Refer to Limit Switch Connectors for
details on SC Connectors.
• When routing wires into the conduit opening, be sure that cuttings
and other foreign matter do not enter the Switch.
Appropriate Tightening Torque
A loose screw may result in a malfunction. Be sure to tighten each
screw to the proper tightening torque as shown below.
*1. This torque range applies to side mounting or bottom mounting. (M4 screws)
*2. This torque range applies to diagonal side mounting. (M5 Allen-head bolt)

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
1. The roller arm can be set freely within a range of 225° after
loosening the nut.
2. The roller arm mounting bracket can be set in any direction after
loosening the nut.
• Make sure that the nut is free of foreign substances when the nut is
loosened.
• A dedicated wrench is provided separately.
