What is a Latching Relay ?

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 switches 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 action of the Permanent Magnet Shunt, and the switching of its switching state is triggered by a pulsed electrical signal of a certain width.


Magnetic latching relays are divided into single-phase and three-phase. According to relevant information, the Electric Silver Contact switching current of magnetic latching relays on the market can reach up to 150A; the control coil voltage is divided into DC9V, DC12V and so on. The general electrical life is 10,000 times; the mechanical life is 1,000,000 times; the Electrical SIlver Contact Rivet voltage drop of the contact is less than 100mV. Therefore, Brass Terminal Lead Shunt Resistor of latching relay has the characteristics of power saving, stable performance, small size, large carrying capacity, and superior performance than general electromagnetic relays.

The structure of the Magnetic Latching Relay

The magnetic latching relay is divided into two layers, the upper layer is the electromagnetic system, and the lower layer is the Silver Electric Contact system. The electromagnetic system adopts a flat direct-acting magnetic latching magnetic circuit system, which includes a Terminal Block Manganin Shunt, a coil, an Electrician pure iron armature, an Electrician pure iron core, and a mounting plate. The Prepayment Meter Shunts are located on the mounting plate. In the center, coils are installed on both sides of the Cable Wire Shunt Resistor, a U-shaped iron core is arranged above the coil, and the armature is positioned between the iron cores to form an annular structure, which can be controlled by a Primary Wire Manganin Shunt field. Both ends of the mounting plate are located beside the U-shaped bottom of the iron core, and a pure iron plate is also installed to prevent the interference of external Braze Welding Shunt Resistance fields (for Energy Meter ).
