The invention relates to a sensor arrangement () for detecting a position and/or a displacement of a flux element assembly () along a longitudinal direction, with a coil assembly () and the flux element assembly (), wherein the coil assembly () comprises at least two flat coils (), wherein the flux element assembly () comprises at least two flux elements (), wherein the at least two flux elements () are arranged adjacent to one another in the longitudinal direction and offset in transverse direction, wherein the flux element assembly () and the coil assembly () are movable and/or displaceable relative to one another in the longitudinal direction, wherein the flat coils () are designed, such that an actual inductance (L, L) of each flat coil () is dependent on the actual displacement of the flux element assembly () relative to the coil assembly (), with an evaluation device, which is set up to determine the actual inductance (L, L) for each flat coil () and determine the actual displacement based on the determined actual inductances (L, L).

Inductive displacement and/or position detection

A driver assembly comprises a predetermined number of semiconductor switches, wherein one of the semiconductor switches is arranged inside of a circular curve and the remaining semiconductor switches are arranged on the circular curve.

Driver assembly

A device for inductive position determination comprises a coil, a positional element, a scanning device for determining an inductance of the coil and an evaluation device for determining a position of the positional element in relation to the coil, based on the inductance determined. In certain embodiments, the positional element comprises a ferromagnetic and electrically insulated material.

Inductive position determination

A driver assembly comprises several semiconductor switches that are arranged in a plane so that distances between adjacent semiconductor switches in the plane are equally large, and so that each semiconductor switch has the same number of adjacent semiconductor switches.
