Magnetic position detector for use in industrial plants and machine tools has a planar detector with detection coils and an excitation coil that is wound around an iron core mounted behind a circuit board with the detection coils

摘要

Magnetic position detector comprises a first magnetic component with a repeating shape, e.g. a gear wheel, whose teeth form the repeating shape, and a second detector component (101) with detection coil patterns (102a - 102d) and an excitation coil for generating an alternating magnetic field that interacts with the first component. This excitation coil is wound around an iron core that is fastened to the rear side of the plate type detector with its detection coils mounted on a circuit board.
