Notes: 1. The coil current ranges is ±15% for AC (60 Hz), ±10% for DC (20°C 68°F). 2. These relays are applicable to a range of 80% to 110% of the nominal coil voltage. However, it is recommended that the relay be used in a range of 85% to 110% of the nominal coil voltage, taking the temporary voltage variation into consideration. For AC types, when operating voltage is 70% of nominal coil voltage, “buzzing” will
occur, and a large amount of current will flow, burning the coil. 3. Each coil resistance of DC types is the measured value at coil temperature of 20°C 68°F. Please compensate the coil resistance by ±0.4%, each time the coil temperature changes by ±1°C.

NOTES Please use the hold-down clip whenever HG relays will be used in applications where strong vibrating or shock force occurs. When used in such applications,
mount the relay so that this force does not parallel the direction of contact movement.
