MY2K-02

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.

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. ■ Contact Ratings Item Rated load Rated carry current Max. switching voltage Max. switching current Max. switching power Failure rate* (reference value) *Note: P level: λ60 = 0.1 x 10-6/operation 3A 250 VAC, 125 VDC 3A 660 VA, 72 W 1 mA at 1 VDC 176 VA, 36 W Resistive load (cosφ = 1) 3 A at 220 VAC, 3 A at 24 VDC Inductive load (cosφ = 0.4) (L/R = 7 ms) 0.8 A at 220 VAC, 1.5 A at 24 VDC ■ Characteristics Contact resistance Set time Reset time Max. operating frequency Insulation resistance Dielectric strength Vibration resistance Shock resistance Endurance Ambient temperature Ambient humidity Weight 50 mΩ max.

Resistor is for ampere-turn compensation and is incorporated in the Relay rated at 50 VAC or above. 2. Pay attention to the polarity of the set and reset coils, as incorrect connection of positive and negative terminal will result in the Relay malfunctioning. When using the Relay rated at 110 VAC at a supply voltage of 220 VAC, be sure to connect external resistors Rs and Rr to the Relay. If the supply voltage is applied to the set and reset coils at the same time, the Relay will be put in the set state. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
