What are the classifications of magnetic latching relays

Update:07-03-2022
There are many types of relays, so how do we classify them? Below we classify the magnetic latching relays according to their working principle, product usage, external dimensions, protection features, contact loads.Classify according to the principle of action of relays.Electromagnetic Relay.Under the action of the current in the input circuit, a relay that produces a predetermined response by the relative movement of the mechanical parts.

It includes DC electromagnetic relays, AC electromagnetic relays, magnetic latching relays, polarized relays, reed relays, energy-saving power relays.DC electromagnetic relay: an electromagnetic relay whose control current in the input circuit is DC.AC electromagnetic relay: an electromagnetic relay whose control current in the input circuit is AC.Magnetic Latching Relay: When the magnetic steel is introduced into the magnetic circuit, after the relay coil is de-energized, the armature of the relay can still remain in the state when the coil is energized, with two stable states.

Polarized DC Immunity current transformer Relay: A DC relay whose state changes depending on the polarity of the input excitation.Reed relay: A relay that uses the action of a reed sealed in a tube and has the dual functions of a contact reed and an armature magnetic circuit to open, close or switch circuits.The control current in the input circuit of the energy-saving power relay is an AC electromagnetic relay, but its current is large.
