Abstract (en)
[origin: WO2017050786A1] The invention relates to an inductive proximity switch, comprising at least one sensor coil (1) for producing an alternating magnetic field in order to detect a conductive target in a monitoring zone and comprising a pre-damping element (2), which are jointly arranged on a circuit board (3), and comprising an oscillator circuit (4) for feeding the sensor coil (1) and an evaluating circuit (5) for producing a binary switching signal, wherein the pre-damping element (2) has a ring, which is interrupted in at least one location and has a connection for adjusting the impedance of the ring, which connection is connected to the evaluating circuit.
