OVERVIEW

Magnetic latching relay is a new type of relay developed in recent years, and it is also an automatic switch. Like other electromagnetic relays, it automatically turns on and off the circuit. The difference is that the normally closed or normally open state of the magnetic latching relay is completely dependent on the function of the permanent magnet, and the switching state of the magnetic latching relay is triggered by a pulse of a certain width.

 

Principle

The open and closed state of the magnetic latching relay is usually held by the magnetic force generated by the permanent magnet. When the contacts of the relay need to be opened or closed, only the positive (reverse) DC pulse voltage is used to excite the coil, and the relay completes the state transition between opening and closing in an instant. Normally, when the contact is in the holding state, the coil does not need to continue to be energized, and only the magnetic force of the permanent magnet can maintain the state of the relay.
