Abstract

An inductive proximity sensor for detecting the proximity of an external object, comprises a sensing part (10) including a sensor coil (12) for generating a magnetic field, a first temperature sensor (14) arranged at the sensing part and configured to provide a first temperature signal, at least a second temperature sensor (26) arranged at a distance from the first temperature sensor and configured to provide a second temperature signal, and an evaluation part (20). The latter is configured to provide a primary detection signal based on detected variations of the magnetic field caused by the external object and to correct the primary detection signal based on at least the first and second temperature signals in order to provide an output detection signal which is related to the proximity of the external object and compensated for a temperature change.
