6VDC electromechanical relay 721

48VDC1 NOfor printed circuit boards

For new developments we recommend to use relay type 725. 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 position 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. Optionally the relay can also be set by manual operation. The relays are designed and manufactured in accordance to international standards of IEC 61810 part 1 as well as they meet the UC3 requirements for Supply Control Switches as of IEC 62052 part 31.
