The difference between Magnetic Latching Relay and Motor Latching Relay
As two of the most popular mini-relays in the field of industrial control, the magnetic latching relay and the magnetic immune latching relay, it is believed that most people do not know the difference between them.
Unlike magnetic latching relays, motor latching relays are smaller and less expensive, unlike magnetic latching relays,it operate by an internal mini motor, so it more affordable than magnetic latching relay.

From above picture, we can see that there are mainly 3 different points in these 2 latching relays,Let's take a closer look at the specific differences.
1. Driving mode: The magnetic latching relay operates on the magnetic field generated by the coil, while the motor latching relay (motor type relay) is driven by the internal part-motor.The driving voltage of magnetic latching relay is usually 6/9~48VDC, while the driving voltage of motor latching relay is usually 9~36VDC.
2. Size: Motor relays tend to be smaller than magnetic latching relays.
3. Pick-up & release time: The pick-up & release time of magnetic latching relay is far less than that of motor relay. The pick-up & release of common magnetic latching relay is ≤20ms, while the pick-up & release time time of motor latching relay is usually 65~120ms.
4. Coil state: The coil state of magnetic latching relay mainly consists of single coil and double coil, while the coil state of motor relay is usually single coil.
Therefore, it has many advantages of energy saving, stable performance, small volume, large carrying capacity. It has more superior performance than the general electromagnetic relay.When we talked here,we have to mention the Chinese Shanghai IVY electronic technology company relay, the company with its excellent service and product quality, popular for more than 20 years, to learn more please click http://www.ivy-metering.com.
