Non Contact Temperature Sensor

Electronic switches offers Non Contact Temperature sensor Infrared Thermometers allow users to measure temperature in applications where conventional sensors cannot be employed. Specifically, in cases dealing with moving objects (i.e. Rollers, moving machinery or a conveyor belt), or where non contact measurements are required because of contamination or hazardous reasons (such as high voltage) where distances are too great for thermocouples or other contact sensors. Sensor has quick response time 150ms. Housing is Rugged IP 65 (NEMA-4) Aluminium housing.

Compact and round shaped enabling installation in limited space.


  • NPN, PNP or Both outputs
  • Multiple ranges available as required
  • LED indication for output status
  • Non Critical alignment between the Sensors
  • Available in M 18 Brass Plated Housing
  • Also available in ABS Plastic Housing
