The NC sensor employs SEMITEC's original IR detection structure which allows the use of non-contact sensors in demanding environments that had previously not been possible. The sensor assembly consists of two high-precision thermistors. One detects IR radiation emmitted from an object, and the other measures the ambient temperature for compensation. By using the temperature differential between the two measurement outputs the target temperature can be calculated.

SEMITEC'S NC sensor is fully compliant with RoHS DIRECTIVE2011/65/EU.
