Operating Characteristics

Safety Precautions
Refer to Safety Precautions for All Limit Switches.
Handling
Do not impose a load exceeding 29.42 N on the cable, otherwise the
cable may break. If the cord is to be bent repeatedly, make sure that
the bending radius is at least R20 mm.
Mounting
Do not tighten the nuts with excessive torque. Refer to the following
for the appropriate tightening torque and mounting dimensions of
each nut.
The base incorporates special threads that cannot be mounted to
plates with standard tap holes.
The base may be deformed if it is subjected to an excessive load.
Be careful when mounting the Switch.
Operation
Do not impose excessive force on the actuator. Even though the
actuator withstands a maximum force of 14.7 N, if the D5B is
repeatedly actuated, make sure that the maximum force imposed
on the actuator is 1.96 N. If the actuator is, however, a wire spring
type, the maximum force imposed must be 0.49 N instead.
The operating characteristics of the D5B vary with the direction (i.e.,
X, Y, or Z) in which force is imposed. Refer to above.
The wobble stick model is actuated when force is imposed on the
tip of the wobble stick and the built-in switch unit is closed or
opened. This is different from the NL Limit Touch Switch or D5C
Column Touch Switch in terms of the main mechanism. The NL or
D5C is actuated when the actuator comes into contact with an
actuating object.
The wobble stick model may break if the stroke is excessive. Make
sure that the total travel (TT) is within the reference value provided
in the datasheet.
Attach an appropriate cover for protecting the D5B from direct
exposure to sprayed oil or water. No protective cover is, however,
provided together with the D5B.
The D5B may be damaged by ozone and failures may result if the
D5B is used outdoors. Consult your OMRON representative before
attempting to use the D5B outdoors.
Outdoor environmental conditions may have a bad influence on the
service life of the D5B. Refer to the general precautions of Limit
Switches for details.
