12VDC electromechanical relay 740

48VDC2 NOpower

Using the H-armature principle the polarised latching relays are noted for their high resistance to shocks and vibrations. They are always in a defined switching-posi- tion and therefore there is no loss of information in case of power failure. The advantage of polarised latching relays is the pulse driven operation of some milliseconds, coil heating can be neglected. The relays are designed and manufactured in accordance to international Standards of IEC 61810 part 1 as well as they meet overload and short circuit requirements acc. to ANSI C12.
