Precautions
Correct Use
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 se-
cure 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.
Sealing materials may deteriorate when used outdoors or when ex-
posed 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 me-
chanical life and performance of the Limit Switch. The use of molyb-
denum disulfide grease is recommended.
Correct Tightening Torque
A loose screw may result in a malfunction. Be sure to tighten each
screw to the proper tightening torque as shown below.

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