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[]A-E, PYF[]-S and PYF-[]-PU 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.

*1. The information in parentheses is the model number of the applicable Mounting Bracket. Mounting Brackets are sold in sets of two. However, the PYC-P is just one Mounting Bracket.
*2. The PYF[]A-E has a terminal cover with finger protection. The Socket and Terminal Cover are integrated into one unit. Round terminals cannot be used. Use forked terminals or ferrules instead.
*3. A Push-In Plus Terminal Block Socket functions as a release lever to hold or remove a Relay. Refer to PYF-[][]-PU/P2RF-[][]-PU for details.
*4. If an MY[]I(S) Relay with a Latching Lever is used in combination with a PY[]-02 Socket for Relays with PCB Terminal Socket and PYC-P Mounting Brackets, the lever will not operate.
*5. We recommends using the PYC-E1 Mounting Bracket for a MY2I(S) Relay with Latching Lever. (If the PYC-A1 is used with the MY2I(S), the latching lever will be blocked by the Mounting Bracket and the lever will not operate.)
*6. The Mounting Brackets are applicable for Relays with a height of 36 mm or less. If the Relay height is greater than 53 mm, use Y92H-3 for the Front-mounting Socket and PYC-1 for the Back-mounting Socket. (The Y92H-3 is a set of two Brackets and the PYC-1 is just one Bracket.)

Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C 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 23°C.
4. The maximum voltage capacity was measured at an ambient temperature of 23°C.
*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.

*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.
