Applications of Magnetic Contact Sensors
Door magnetic switches are widely used in modern security and automation systems. These sensors detect the opening and closing of doors, windows, gates, cabinets, and other movable access points by sensing changes in the magnetic field.
Typical applications include:
- Burglar alarm and intrusion detection systems
- Access control and entry monitoring systems
- Smart home security automation
- Commercial building security systems
- Industrial safety and equipment monitoring
- Warehouse and logistics security
- Data center cabinet and rack monitoring
