Proximity Switches (Magnetic Rectangular)


 

Proximity switches and sensors use a reed switch and a permanent magnet. Each is encased in a plastic housing for protection and ease of mounting. A classic use is sensing the opening of a door in a security system. A reed switch in the jamb and a permanent magnet in the door complete a circuit when the door is closed. Opening the door breaks the circuit.

Proximity switches can be achieved using a number of different technologies depending on the application. Use the contact information button to request help with choosing the right proximity switch for you application.
