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.
