Abstract
A sensor for locating metal objects has coils or coil parts which form at least one transmitting coil () and at least one receiving coil () which are inductively coupled to one another and are arranged such that said coils partially overlap for the purpose of interaction decoupling, wherein optimum cancellation of the interaction can be achieved. Sensor electronics are provided for energizing the transmitting coil and for evaluating a reception signal () from the receiving coil. As a result of the fact that the transmitting coil () and the receiving coil () substantially have an identical coil shape and are arranged such that said coils are rotated and/or offset with respect to one another, wherein a plurality of symmetrically arranged, overlapping regions () are formed, a sensor which provides a greater range and extended possibilities for installation in conventional industrial sensor housings is provided.
