Position detection based on reed switches

Position detection based on reed switches

Proximity switches work contact-free. The contact is actuated by the magnetic force as soon as a permanent magnet gets close to the contact. Proximity switches are often used in the testing and measuring technology, telecommunication, safety engineering or in households.

The correct switching distance can be set by adjusting the magnetic sensitivity of the reed switch and selecting the right magnetic material. The installation situation and the approach direction of the magnet are always important in this process, though.

As the proximity switches are based on reed switches, there is no permanent power supply required, which makes this type of sensor very energy-saving. Due to the design of the reed switch, the sensor can be used in virtually any environment. The typical switching frequency of a reed switch is at 109 switching cycles, which guarantees a long service life.

We supply all proximity switches with a 1 m cable as a standard but cable length can be adjusted according to your individual needs.

Product features:
– M5 & PG9 made of stainless steel (Mat. no. 1.4571)
– M8 made of nickel-plated brass (Mat. no. 2.0321)
– M6 & M8 made of plastic material
– and our R26 enclosure, also made of plastic material

The R26 plastic enclosure with PCB plug-in developed by HLM allows for the variable production of customer-specific models. The PCB will be assembled with components according to your needs. Flexibility is our top priority. Whether one single reed switch, a Namur switch or an integrated temperature measurement, complemented with a cable, a pair of strands or a plug – the sensor is completely encapsulated.


We are look forward to your contact.
