An inductive proximity switch with a housing formed of a nonmagnetic, high-grade steel, with a transmitting coil, two receiving coils which are connected in series in opposite directions and which are located symmetrically relative to the transmitting coil, and an evaluation circuit which is connected to the receiving coils. At a given size, the inductive proximity switch has a relatively large operating distance and the operating distance is largely stable, especially is largely independent of temperature, essentially in that, on the back of the receiving coils, opposite the influence side, there is a pre-damping element and the pre-damping properties of the pre-damping element at least approximately correspond to the pre-damping properties of the housing on the influence side.
