Safety Precautions
Refer to Warranty and Limitations of Liability.
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Do not use this product under ambient conditions that exceed the
ratings.
● Design
Influence of Surrounding Metal
When mounting the Sensor within a metal panel, ensure that the
clearances given in the following table are maintained. Failure to
maintain these distances may cause deterioration in the performance
of the Sensor.
Influence of Surrounding Metal (Unit: mm)
Mutual Interference
When installing two or more Sensors face-to-face or side-by-side,
ensure that the minimum distances given in the following table are
maintained.
Mounting
Do not tighten the nut with excessive force. A washer must be used
with the nut.
Note: The following torque assume washers are being used.

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.

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.
