Abstract
The present disclosure relates to a proximity sensor having a coil () for generating a magnetic field and a sensor circuit () for detecting variations of the magnetic field caused by an external object, the sensor circuit () comprising at least one semiconductor component () mounted on a circuit board (), wherein the coil () and the circuit board () are arranged in a housing () through which the magnetic field is transmittable. In order to improve the resistance of the proximity sensor against harmful external influences, such as high temperatures, and to prolong its life cycle, the invention suggests that the semiconductor component () is included in an enclosure () that is hermetically sealed and fixed on a surface () of the circuit board ().
