Miniature Power Relays
MY
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.
Refer to the Common Relay Precautions.

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.

Note: 1. The rated current and coil resistance are measured at a coil temperature of 23C with tolerances of +15%/20% for the AC rated current and 15% for the
DC coil resistance.
2. The AC coil resistance and inductance values are reference values only (at 60 Hz).
3. Operating characteristics were measured at a coil temperature of 23C.
4. The maximum voltage capacity was measured at an ambient temperature of 23C.
*1. There is variation between products, but actual values are 80% max.
To ensure operation, apply at least 80% of the rated value (at a coil temperature of +23 C).
*2. There is variation between products, but actual values are 30% minimum for AC and 10% minimum for DC. To ensure release, use a value that is lower than the
specified value.
