Working Principle and Supplementary Instructions

Principle

The magnetic latching relay is a new type of relay developed in recent years. Unlike normal relay, the ON or OFF state of magnetic latching relay depends on the action of a permanent magnet, and the state switching is triggered by a certain width of pulse electric signal. Once set or reset, the relay remains in the current state even when powered off. The magnetic latching relay features low power, steady performance, long service life, and low-temperature rise.

Other Supplementary Information

1. The factory state of magnetic holding relay is reset state, but it may change to set state due to impact during transportation or installation, so please change the state to set or reset according the actual needs when using (when the power is connected).

2. To ensure the set or reset of the magnetic holding relay, the excitation voltage applied to the coil must reach the rated voltage, and the pulse width must be greater than 4ms. the set and reset coil should not be powered simultaneously. Do not apply voltage to the coil for a long time (more than 1 minute).

3. In the process of product transportation, storage and application, please keep the product away from the strong magnetic field to avoid the change of set and reset voltage.
