|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 characteristic such as contact follow, contact pressure, etc., throughout 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.

1. For AC type, the rated current values are halfwave 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 +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 to 35°C.
