Magnetic sensors

Magnetic sensors are preferably applied as an alternative to mechanically operated limit switches in cases where unfavourable operating conditions, such as high or low actuating speeds, large switching frequencies, extreme dirt or dust production, high humidity, chemical atmospheres, high fluctuating actuating distances etc. occur. Even in the presence of aggressive materials, as well as in the food processing industry, safe switching is ensured through the encapsulation of the contacts. Thus magnetic sensors are suitable for e.g. movement and standstill monitoring on machines and systems, as electronic counter, as station switch on conveyor systems and high rack warehouses, as well as for position indication of flaps, slide feeds and valves.

In the lift industry magnetic sensors are suitable for positioning and controlling lift cabins. A further field of application is the electronic control of the travel and the position indication on pneumatic cylinders.

The magnetic sensors are actuated by permanent magnets wihtout any mechanical contact. The devices can be selected either with one NO, NC, change-over or latching contact. The magnetic sensors are provided with cable or plug-in connector.

The magnetic sensors for control and positioning on pneumatic cylinders are actuated by permanent magnets fitted inside at the piston of the pneumatic cylinder.
