magnetic latching relay

GDL Magnetic Latching Relay

Magnetic latching relay is a special motor relay with self-locking function. They use a magnetic system to keep the relay closed without requiring a continuous application of current. When a trigger signal is applied to the relay, the magnetic system generates enough magnetic force to pull and hold the contacts in that state.

This type of relay is typically used in applications that need to remain on and off for extended periods of time, such as automatically switching circuits in the event of a power failure. They can also be used to control robots and automated systems. Some of the advantages of latching relays include high stability, low power requirements, and long life
