Omron MYK DATASHEET

General-purpose Latching Relay

MYK

Magnetic Latching Relay Ideal for Memory
and Data Transmission Circuits

• Double-winding latch system that holds residual magnetism.

• Changes due to aging are negligible because of use of special
magnetic materials, thus ensuring long continuous holding time.

• Little change in characteristics such as contact follow, contact
pressure, etc., throughout its long life.

• Excellent vibration/shock resistance.

• Easy monitoring of ON/OFF operation thanks to the built-in op­eration indicator mechanism.

• Same outline dimensions as the MY Miniature Power Relay.

Note: 1. For AC models, the rated current values are half-wave rectified current values measured with a DC ammeter.

2. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/–20% for AC rated current and

±15% for DC rated current, and +15% for DC coil resistance.

3. The AC coil resistance values are for reference only.

4. Performance characteristic data are measured at a coil temperature of 5°C to 35°C.
