Precautions for Correct Use
Handling
Operation
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.

• 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.
• The base may be deformed if it is subjected to an excessive load.
Be careful when mounting the Switch.

machine, system, or other application or use.
The following are some examples of applications for which particular attention must be given. This is not intended to be an exhaustive list of all possible
uses of the products, nor is it intended to imply that the uses listed may be suitable for the products:
 Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in this catalog.
 Nuclear energy control systems, combustion systems, railroad systems, aviation systems, medical equipment, amusement machines, vehicles,
safety equipment, and installations subject to separate industry or government regulations.
 Systems, machines, and equipment that could present a risk to life or property.
Please know and observe all prohibitions of use applicable to the products.
NEVER USE THE PRODUCTS FOR AN APPLICATION INVOLVING SERIOUS RISK TO LIFE OR PROPERTY WITHOUT ENSURING THAT THE
SYSTEM AS A WHOLE HAS BEEN DESIGNED TO ADDRESS THE RISKS, AND THAT THE OMRON PRODUCTS ARE PROPERLY RATED AND
INSTALLED FOR THE INTENDED USE WITHIN THE OVERALL EQUIPMENT OR SYSTEM.
PROGRAMMABLE PRODUCTS
OMRON shall not be responsible for the user's programming of a programmable product, or any consequence thereof.
Disclaimers
CHANGE IN SPECIFICATIONS
Product specifications and accessories may be changed at any time based on improvements and other reasons.
It is our practice to change model numbers when published ratings or features are changed, or when significant construction changes are made.
However, some specifications of the products may be changed without any notice. When in doubt, special model numbers may be assigned to fix or
establish key specifications for your application on your request. Please consult with your OMRON representative at any time to confirm actual
specifications of purchased products.
DIMENSIONS AND WEIGHTS
Dimensions and weights are nominal and are not to be used for manufacturing purposes, even when tolerances are shown.
PERFORMANCE DATA
Performance data given in this catalog is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the
result of OMRON’s test conditions, and the users must correlate it to actual application requirements. Actual performance is subject to the OMRON
Warranty and Limitations of Liability.
