Like other electromagnetic relays, the magnetic latching relay is also an automatic switch, which automatically turns on and off the circuit. It is a bistable relay that relies on its own permanent magnet to keep the contacts open or closed.
A magnetic latching relay is a relay that uses permanent magnets or parts with high remanence characteristics to keep the armature of the electromagnetic relay in the position when the coil is energized after the coil is disconnected. According to the definition, the biggest difference between the magnetic latching relay and the general relay is that it does not need to be energized during this period to maintain the armature state,
China Magnetic latching relays Manufacturers while other relays need to continue to use electricity. Therefore, the biggest advantage of magnetic latching relays is power saving! Of course, the price is relatively high.
Matters needing attention in the use of magnetic latching relay:
Avoid energizing both coils at the same time (if energizing at the same time, the relay is in the set state). The reset voltage must not exceed 150% of the rated voltage, otherwise it may be reset. When selecting spare parts, as long as the installation position, coil voltage and contact current can meet the requirements.
The use of the relay should meet the various parameter ranges listed in the product manual as far as possible. Rated load and life are a reference value, which will vary greatly according to different environmental factors, load properties and types, so it is best to confirm in actual or simulated actual use. Try to use rectangular wave control for DC relays, and use sine wave control for AC relays.
