Abstract:
An inductive proximity sensor is disclosed. The proximity sensor includes a housing having at least a first pair of inductive coils disposed within the housing. One of the first pair of inductive coils is opposite in polarity from another one of the first pair of inductive coils. The sensor optionally includes a second set of inductive coils, having opposite polarity.
