Magnetic switches as proximity sensors
How does a Reed magnetic switch work?
Magnetic switches are based on the tried-and-tested Reed contact-magnet principle, which guarantees reliable and durable functionality. A Reed contact installed in the housing is actuated by the magnetic field of a magnet. The switching state of the Reed contact can be evaluated and further processed by a downstream control device.
Examples of use:
- Door contacts
- Air-conditioning system control units
- Position monitoring of processes
- Alarm systems
- Fill-level monitoring
Our sensors identify the magnets from a defined distance and detect whether, for example, a door is open or closed.

What makes a Reed magnetic switch stand out from the competition?
Reed magnetic switches work without contact having to be made, which reduces wear and tear to a minimum and guarantees that the product has a long service life. The magnetic switches can be easily installed, work in a potential-free manner and do not require supply voltage.
Advantages of the Reed magnetic switches
There is no friction, which reduces the wear and tear to which the magnets are subjected to a minimum and guarantees a long service life for the product.
Due to a Reed contact being used, no auxiliary power is required to operate the sensor.
Precise switching distances subject to the reference magnet. Available in a bistable design as a normally open, normally closed or changeover contact.
Magnetic switches designed exactly to your requirements in different designs and materials.
