combination of the Product in the Buyer’s application or use of the Product. At Buyer’s request, Omron will provide applicable 
third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself is 
not sufficient for a complete determination of the suitability of the Product in combination with the end product, machine, system, 
or other application or use. Buyer shall be solely responsible for determining appropriateness of the particular Product with 
respect to Buyer’s application, product or system. Buyer shall take application responsibility in all cases.

Performance Data.

Data presented in Omron Company websites, catalogs and other materials 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 user must correlate it 
to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations of Liability.

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 part numbers when published ratings or features are changed, or when significant construction changes are made. 
However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers may be 
assigned to fix or establish key specifications for your application. Please consult with your Omron’s representative at any time to 
confirm actual specifications of purchased Product.
