摘要： Present techniques provide an inductive proximity sensor having a multi-receiver coil assembly and an evaluator circuit configured to receive a differential signal from the multi-receiver coil assembly to determine the presence of a target. The multi-receiver coil assembly includes two receiver coils in a differential coil arrangement and a transmitter coil configured to emit an electromagnetic field and induce a voltage on each of the receiver coils. The voltage difference between the two receiver coils is transmitted as a differential signal to the evaluator circuit. Targets which approach the inductive proximity sensor disrupt the electromagnetic field and change the induced voltages on each of the receiver coils, thereby changing the differential signal. The evaluator circuit processes the differential signal to determine whether the changes indicate that a target is present.

摘要： Inductive proximity switch has a first transmitting coil (S1) and a first receiving coil (E1) of a receiving coil arrangement. The transmitting coil (S1) transmits an exciting field inducing eddy currents in a metallic trip (1) brought into the vicinity of the proximity switch. The eddy currents generate a voltage-inducing eddy current field in the first coil (E1) of the receiving coil arrangement. The first coil E1 and a second coil (E2) of the receiving coil arrangement are disposed and connected so that the exciting field generates a differential voltage (3), in the receiving coil arrangement. A pair of compensating coils includes the second coil (E2) of the receiving coil arrangement and a compensating coil (S2) connected in series with the transmitting coil (S1), the pair of compensating coils being isolated from the eddy current field.
