Non-Contact Infrared Sensors

ATC Semitec supply two forms of infrared sensor that measure high precision temperature measurement- by remotely detecting infrared heat from the target object – therefore providing measurement without any impact or physical effect.


These are ideal for surface temperature measurement over other alternatives such as contact probes where the measurement of thin film plastics, paper or high temperature glass or metals is almost impossible using traditional methods.

The NC sensor is a robust non-contact sensor primarily designed for use in office automation and other products with rotating motors whereas the thermopile is a very fast acting infrared sensor, often used in clinical thermometers.

Call us today on 01606 871680 to discuss your application’s thermal sensor requirements.  Using our extensive technical knowledge and innovative supplier base, we will work with you to provide the optimum solution for your product.


  • NC Non-Contact Sensors F-Type

    Utilising micro FT thermistor technology, Semitec have developed a sensor which can be easily installed, is self-compensating and can withstand more aggressive environments than conventional infra-red sensors.

    • High dust resistance
    • Operating temperature range: -10°C to 150°C
    • Resistant to electrical noise
  • Thermopile Non Contact Sensor
    Thermopiles - Non-Contact Infrared Sensors

    The Semitec 10TP series thermopile is a very fast-acting infrared sensing device suitable for non-contact applications.

    • Operating temperature range: -10°C to +100°C
