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