The Difference Between Normal Relay And Self Latching Relay
Nov 03, 2017

The difference between normal relay and self latching relay

The relay can be divided into single side steady state, single coil self holding type and double coil self holding type.

Matsushita Electric has many relays, such as TQ, DS, DSP, DE, RX, DJ, DK, S, ST, JH, RJ, and so on. The self latching relay has a good power saving function compared with the conventional relay, so more and more common relays are replaced by the conventional relay.

Steady state relays (unilateral common relay):

Unilateral steady coil power relay is a relay coil set, the power is reset


Double coil self holding type:

The self retaining structure of the double coil self latching relay consists of two coils, a set coil and a reset coil. When the pulse is placed on the set coil, the relay is placed, and the pulse is reset when the reset coil is pulsed

Single loop self holding type:

The single loop self latching relay has a self retaining structure. After the input of a forward pulse on the loop, the relay keeps its position, and the input reverse pulse relay is reset
