Abstract
Inductive proximity switch has a first transmitting coil (S) and a first receiving coil (E) of a receiving coil arrangement. The transmitting coil (S) transmits an exciting field inducing eddy currents in a metallic trip () brought into the vicinity of the proximity switch. The eddy currents generate a voltage-inducing eddy current field in the first coil (E) of the receiving coil arrangement. The first coil Eand a second coil (E) of the receiving coil arrangement are disposed and connected so that the exciting field generates a differential voltage (), in the receiving coil arrangement. A pair of compensating coils includes the second coil (E) of the receiving coil arrangement and a compensating coil (S) connected in series with the transmitting coil (S), the pair of compensating coils being isolated from the eddy current field.
