The models in this table are UL/CSA certified. This is indicated with a certification mark on the products.
(This does not include models with high contact reliability or plastic sealed, latching, or hermetically sealed models.)
2.
Models with an asterisk (*) next to them are new versions.
3.
The standard models with plug-in terminals, models with coil surge absorption diodes, and models with coil surge absorption CR circuits were used in
combination with the PYF-E and PYFS (2-pole and 4-pole) for the EC Declaration of Conformity. These products display the CE Marking.
4.
Products cannot be manufactured for the cells with a diagonal line. Ask your OMRON representative for details on manufacturing products for cells containing
“---” in the above table.
