I would like to share with you some thoughts on the future development trends of latching relays. As an electrical component widely used in the field of automation control, latching relays have made considerable progress and have been extensively validated in practical applications. So, what new directions can we expect latching relays to take in the future? Let's explore together.

The accuracy is unchanged for a long time, and there is no need to run the school, no installation and transportation, etc.

​Magnetic latching relay factory condition for contact closure state,but because carry or installed when subjected to impact,may change state,therefore before use to make its reset.

Tongue spring relay: a relay that opens, closes or converts the line with tongue spring action that is sealed in the tube and has the dual role of electric shock reed and arbit magnetic circuit

A relay is an electrical control device. It has a control system (also known as input loop) and a quilt The interaction between control systems (also known as output loops). Usually applied to the control of automation

​The relay coil is represented in the circuit by a long box symbol, and if the relay has two coils, two long boxes are drawn side by side. At the same time, mark the relay word symbol "J" in or beside the long box. There are two ways to represent the contacts of relays: one is to draw them directly on one side of the long box, which is more intuitive. The other is to draw each contact into its own control circuit according to the needs of the circuit connection. Usually, the contact of the same relay and the coil side are marked with the same text symbol, and the contact group is numbered to show the difference.

Self-locking and interlocking are achieved by auxiliary contacts of relays. First of all, you need to understand what is called self-locking and what is called interlocking. Self-locking is to short off the button switch of the contactor coil loop with your own contacts, and make the coil loop open continuously after the button switch is released, which is self-locking.

3 groups of 120A contact switching capability Contact on-off detection auxiliary switch can be provided Coil control single and double coil optional

Please apply a suitable voltage to the coil according to the coil polarity specified in the manual, otherwise the operating voltage of the relay will increase or even not operate; it needs to be changed When driving the polarity, please use the "-R" type relay.

Latching refers to "self-locking", which means that after the relay is energized, its state is automatically locked and the circuit is kept connected. Even if the control current is disconnected at this time, its state will not be changed. That is to say, when the power is energized and absorbed, the control current is disconnected, and it remains on until the unlock button is pressed.
