Miniature Power Relays: MY4
Ordering Information
Note: 1. Ask your OMRON representative for details on the time required to deliver made-to-order products.
2. Ask your OMRON representative for details on product specifications and the ability to manufacture products with voltages other than the above coil
specifications.
3. The above models and specifications are new versions in the MY Series.
4. Except for MY4(N)-CR Relays with the above voltage specifications, all Relays have a height of 53 mm or less.
If Mounting Brackets are required, refer to page 33 for selection information.
Ratings and Specifications
Ratings
Operating Coil (Standard Models)
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
*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.
Contact Ratings
*1. With no icing or condensation.
*2. This limitation is due to the diode junction temperature and elements used.
