Welcome to SEMITEC USA Corp.

Our NC Sensor copes with
the severe environment seen inside microwave ovens.

NC SENSOR-Our Non Contact (NC) sensor is a new concept in measuring infrared heat fortemperature control.
Utilising our own micro thermistor technology, we have developed a sensor which can withstand more aggressive environments than other conventional infra-red sensors.

Real-time heat measurement-Cook at exactly the right temperature

High resistance to dirt build-up Very little deterioration in output is caused by either grease or steam.
High heat resistance Operating temperature range;-10 to 150 deg.C.
Resistant to electrical noise No special housing required in micro-wave applications.
Simple to use Using a thermistor sensor, the signal output is high and very easy to process; helping to reduce other component costs.
