Proximity switches
How does a proximity switch work?
Contactless proximity switches are indispensable within the industrial sector. Compared with mechanical switches, they offer the best conditions – their contactless functionality ensures that there is no wear and tear during operation and thus in turn the switch has a long service life. High switching frequencies and accuracy ensure the accuracy of the switch. The compact design provides guaranteed protection against dust, moisture and vibrations.
The use of sensors as providers of information for control units is an important requirement in every automated process. The sensors provide signals about positions, locations and fill levels and act as the pulser for counting tasks and for measuring speed.

Examples of proximity switch applications
In the industrial sector, autoclaves are used in door systems, where the correct locking position must be in place before pressure can be built up inside the device. For this purpose, up to four magnetic switches may be used. These detect whether the correct locking mechanism is in place and thus create a redundant security system.
Reed Electronics has many years of experience in the area of autoclave locking systems and extensive knowledge of suitable magnets and sensors to meet every need – including for indoor temperatures of up to 140° C. The contactless magnetic switches are designed to be resistant and long-lasting and keep maintenance and wear and tear to a minimum.
Conveyor belts
Contactless sensors can be used to detect positions and objects – and are frequently used for conveyor belts.
Magnetic switches and magnets detect the current situation on a band or an exact position to ensure that objects are positioned in a specific way. These may be containers that need to be filled, which must always be kept in a specified position.
In another area of use, proximity switches detect the presence or absence of mechanical parts with integrated magnets. Magnetic switches may be integrated into different casing shapes and materials, meaning that the sensor can be adapted to the application at hand.
Proximity switches are used in the following sectors, for example
Chemical industry
Our sensors are available in a wide range of materials and can therefore be used in a large number of applications – including in abrasive media such as 30% hydrochloric acid, chlorine or various cleaning agents.
