New Latching Levers for Circuit Checking Added to Our Best-selling MY General-purpose Relays
• Now lead-free to protect the environment. • VDE certification (Germany). • Different colors of coil tape for AC and
DC models to more easily distinguish them. • MY(S) models with latching levers added for
easier circuit checking.

Note: 1. 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.
Refer to Connection Socket and Mounting Bracket Selection Table on page 33 in Options for information on the possible combinations of Models with Plug-in Terminals and Sockets.
