5A ( Form C), A (4 Form C) COMPACT POWER RELAYS WITH HIGH SENSITIVITY RELAYS RoHS Directive compatibility information http://www.mew.co.jp/ac/e/environment/ Taking advantage of the 4-gap balanced armature mechanism, S relays have met a number of relay needs and earned a reputation for the characteristics that they provide. Building on the same structure, the relay was introduced as a highsensitivity power relay to provide nominal operating power of 3 mw and minimum operating power of 5 mw (single side stable and coil latching types). Even so, with the nominal switching capacity for the Form C at 5 A, and for the 4 Form C at A, highcapacity switching is possible with small input. Moreover, taking full advantage of the ecellence of the 4-gap balanced armature mechanism, we have realized a small, slim form factor that also has superior resistance to vibration and shock. This power relay is often chosen for NC machines and electrical power remote monitoring control panels, and for power supplies used in computers and other equipment. The also often provides power control for high-end business and industrial equipment. FEATURES. Small, 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.. High sensitivity The high-efficiency polarized electromagnetic mechanism in conjunction with our eclusive spring alignment method achieves levels of sensitivity higher than relays that have been available up to now. For both the Form C and 4 Form C single side stable and coil latching types, the 5 mw minimum operating power level allows direct driving by transistor or chip controllers. 3. High reliability and long life With a structure that ensures almost perfectly complete twin contact and minimal contact bounce, you get greater reliability than has so far been provided by power relays. 4. Latching types also available coil latching and coil latching types are available. In cases where it was formerly unavoidable to use plural relays for large power memory, you can now use a single relay. 5. Strong resistance to vibration and shock Our balanced armature technology well withstands vibration and shocks. It provides strong resistance to vibration and shock.
