Magnetic Switches Series EEx RC M20

Ex magnetic sensors are suitable for positioning and controlling lift cabins in the lift industry. 

They are generally used as an alternative to mechanically operated limit switches in cases where unfavorable operating conditions, such as high or low actuating speeds, large switching frequencies, extreme dirt or dust production, high humidity, chemical atmospheres, highly fluctuating actuating distances, etc., occur. 

Even in the presence of aggressive materials, safe switching is ensured through the encapsulation of the contacts. 

The Ex magnetic sensors are actuated by an M range permanent magnet, entering their proximity without any physical contact. 

These devices are available with NO, NC, changeover, bistable or bistable changeover contacts. All magnetic sensors described in this section are supplied with pre-wired cables. When using Ex magnetic sensors, care must be taken that their mounting site is free of magnetic fields.
