Abstract

An inductive displacement or rotational angle sensor including at least one electrical coil which is provided with turns, and an influencing element which interacts with said coil and produces a different inductance of the least one coil as a function of its position, characterized in that at least two separate coils which are arranged coaxially with respect to a coil axis and have an axial interspacing are provided, it being possible for the influencing element to enter said interspacing with a degree of overlap, which is dependent on its position, with the magnetic fields which are generated by the coils.
