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 op- eration indicator mechanism. Same outline dimensions as the MY Miniature Power Relay.

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 5C to 35 C.
