Magnetic Proximity Sensors | SICK

Magnetic proximity sensors provide long sensing ranges that can reliably detect magnetic objects, with entirely new application options opened up due to the smaller magnets. MM sensors in NAMUR design for the use in explosion-hazardous areas complete this comprehensive product family. MQ sensors offer all the advantages of a magnetic proximity sensor in a compact plastic housing. Magnetic proximity sensors are designed specifically for use in harsh environments and are unaffected by dust, heat, or vibrations. Typical fields of application are also those where other sensors reach the limits of their technology.

Applications

• Door leaf detection on elevator doors
• Zone detection in elevator shafts
• Position determination on a revolving door
• Door leaf detection on automatic sliding doors
