1) MRS20-1E-1 (10W Version)
2) MRS20-1E-2 (100W Version)
Refer to technical drawings for exact dimensions and mounting configuration.
5. Operation Type
The bistable magnetic latching mechanism maintains state without continuous power, making it ideal for energy-efficient applications.
6. Precautions for Use
1. Environnement: Avoid installation in areas directly exposed to rain, strong magnetic fields, or near objects with thermal radiation.
2. Density: Avoid excessive bulk density in use, which may affect the electrical characteristics of the switch.
3. Mechanical Shock: Excessive mechanical shock strength may change its magnetic sensitivity or even damage the switch.
4. Montage: Use appropriate mounting methods to reduce switching distance and avoid installation on any ferromagnetic material surface.
