Features

 W24-2 Ex
  • Safe and reliable switching in external areas;
  • Corresponds to category 2G according to guideline 94/9/EG (ATEX) and may be used in zones 1 and 2 (gases and fumes);
  • Precise background suppression;
  • Namur switching output.
 
 W18-3 Ex
  • Ready-to-install, standardized model: sensor + protective housing;
  • Complies with category 3D and 3G according to guideline 94/9/EG (ATEX);
  • Precise background suppression;
  • Insensitive to optical interference effects.
 
 W27-3 Ex
  • Ready-to-install, standardized model: sensor + protective housing;
  • Complies with category 3D and 3G according to guideline 94/9/EG (ATEX);
  • Infrared light, very large scanning range;
  • Operation reliability in industrial environments: with optical reflections and equipment mounted opposite.
 

Advantages

 W24-2 Ex
  • Allows longer sensing range despite the limited factors of the norms for Category 2G (ATEX, explosive environments);
  • Metal housing that has been IP 69K tested provides reliability and a long service life;
  • Flexible installation due to 90° rotatable connector.
 
 W18-3 Ex
  • Autocollimation optics and polarizing filters ensure reliable detection of shiny objects;
  • Quick and easy alignment and setup due to highly visible red light;
  • Reliable use in potentially explosive atmospheres;
  • Application-specific sensitivity control via potentiometer;
  • Quick and easy installation due to a wide range of accessories, especially reflectors.
 
 W27-3 Ex
  • Ready-to-install sensors conform to the 3G/3D category for explosive zones (ATEX);
  • Less contamination due to high operating reserves, reducing downtime;
  • Resistant to vibrations, reducing downtime;
  • Withstands harsh environments, making it suitable for a wide range of applications with operating temperatures from -20 °C - +50 °C.
 

Industries
All, wherever an explosive area has been identified and classified (ex. food/cereals, building/paint, energy/liquid and gas fuel, etc).
