Inductive proximity switches for hazardous dust areas II 3D.
 
 

 
 Rectangular designs (for use in zone 22, non-conductive dusts).

Applications
These units are suitable for use in zone 22 hazardous areas with non-conductive dusts according to the category 3D. The design of the proximity switches complies, among others, with the standards EN 50014 und EN 50281-1-1.

The family of units
The rectangular sensors in tried-and-tested plastic housings are available in different sizes from 40 x 12 x 26 mm to 105 x 80 x 40 mm. The range covers dual switches for the detection of valve positions to sensors with extra long sensing ranges for the monitoring of elevators.

Connection options
Units with cable have a 2 m long PVC cable. For the units with M12 connector a locking device (separate order no. E11532) is available which ensures that the connector can only be loosened with the aid of a tool. Units with terminal chamber are fitted with an ATEX-compliant cable gland.
