Abstract
An industrial control sensor is provided. The sensor includes a sensor circuit to detect changes in an electromagnetic field induced from an object or material passing in proximity of the electromagnetic field. This includes a housing that employs the sensor circuit as part of an inductive proximity sensor. A sensor face is attached to the housing, where the sensor face receives the changes in the electromagnetic field and transmits the changes to the sensor circuit, and where the sensor face has a higher electrical resistivity or a lower temperature coefficient of resistivity than stainless steel.
