The SP series 2/4c 10/15A Polarized Power Relay with small and slim form factor. Facilitating the form factor reduction of devices, the overall height of the relay package is less than half that of our HP relay. The high-efficiency polarized electromagnetic mechanism in conjunction with our exclusive spring alignment method achieves levels of sensitivity higher than relays that have been available up to now. For both the 2-form-C and 4-form-C single side stable and 2 coil latching types, the 150mW minimum operating power level allows direct driving by transistor or chip controllers. High reliability and long life with a structure that ensures almost perfectly complete twin contact and minimal contact bounce, get greater reliability than has so far been provided by power relay.
