Handling Precautions
• The recommended tightening torque is 0.5 N•m max.
• Verify that the amount of thread protruding from
the mounting face does not exceed 13 mm. If it
does, the thread will interfere with the clasp that
locks the switch body into position.
• Use of a spring washer or adhesive is recom-
mended to protect the screw from loosening
when used in a high-temperature environment.
●Attachment using adhesives
Useanappropriateadhesivetogluethemountingplate.
Handling Precautions
• Apply a thin coating of adhesive uniformly. Too
much adhesive will cause the detecting face to oat.
• Make sure no adhesive seeps out and sticks to
the edges.
• If any adhesive seeps out and sticks to the switch
body, there may be diculty mounting or re-
moving the switch. In addition, excess adhesive
may interfere with the detecting capabilities of
the device.
