A Magnetic latching relay is a new type of relay. It features low power dissipation and noiseless. Unlike other non-latching relay, the latching relay needs two digital pulse signal to switch ON/OFF state.
This DFRobot Gravity: magnetic latching relay is compatible with most popular microcontrollers such as esp32 / Arduino / Raspberry Pi. It can be used to remake home appliances or lighting controls, like smart electricity meters, lighting, sockets, switches, and so on.
What is Magnectic latching relay?
A latching relay is an automatic switch that stays in its last position when powered off, acting as a memory circuit. It helps reduce power consumption in applications compared to non-latching relays that consume more power. Latching relays have noiseless switching while non-latching relays hum. Magnetic latching relays are ideal for low power and high stability applications due to their low power, steady performance, long service life, and low-temperature rise.
Latching or Non Latching Relay?
Choosing between a latching or non-latching relay depends on the specific requirements of the application. Latching relays are preferred for applications that require low power consumption and low noise levels, while non-latching relays are more economical for situations where a short time delay is needed. The decision should be made by the designer after careful consideration of the application's needs and available options
