Application of Magnetic Latching Relay in Portable Equipment

For many years, people have been pursuing the portable carrying of various electronic devices, especially in the aviation fields such as airplanes and artificial satellites, as well as various portable intelligent instruments. Not only the equipment is small in size, light in weight, and reliable on quality, but also in the endurance of the equipment. With long capabilities, it is indispensable to challenge and check the components used inside the portable device.

As an important automatic switch control element in the circuit, the relay is naturally also developing in the direction of miniaturization and low power consumption. As we all know, the magnetic latching relay is a kind of bistable relay that still maintains the excited state after the excitation is removed. It only needs to pass a certain direction and magnitude of pulse voltage in the coil to realize the conversion of the contact working state, that is, the short It is driven by time pulse, and can still be self-maintained after the pulse passing through the coil disappears.

For saying this is that if you choose an ordinary normally open relay, when the system equipment needs to be powered during normal operation, it needs to continuously energize the relay coil to maintain the smoothness of the circuit, which will generate a certain amount of power consumption, and increase the power consumption of the storage battery, and also the coil is prone to heat when it is energized for a long time, which reduces the service life.

To sum up, the advantages of using magnetic latching relays in portable devices are as follows:

1. Pulse drive is beneficial to save energy and minimize the heating of the coil

2. In the event of a power failure, it still maintains the original state, which can be said to have a "memory" function

3. High sensitivity, over-excitation can be used, so it has a faster movement speed

4. The contact has high contact stability, strong anti-vibration ability, and strong overall anti-shock ability.
