Abstract: An axial piston pump having several pistons has a magnetic encoder (5), which is arranged on a swash plate, and a magnetic field sensor, which is arranged in such a way that it faces towards the magnetic encoder (5). The magnetic encoder (5) has at least two permanent magnets (2, 3) and a plate (4) which consists of a ferromagnetic material. The permanent magnets (2, 3) are arranged on the plate (4) in such a way that they each faces a magnetic pole towards the plate (4), and this pole is at least partially covered by the plate (4) in each case.

Abstract: An actuating system for a valve which can be used as a control valve. The valve system having an outer housing, a receiving region for a switching spindle of the valve, at least one inductive sensor running in parallel to the receiving region, and at least one substantially circular cylindrical position encorder.

Abstract: A switch includes a button which is connected to a ring-shaped permanent magnet that is magnetized along a z-axis, a guide member made from an non-ferromagnetic material inside which the button and the ring-shaped permanent magnet are arranged so as to be moveable along the z-axis, as well as at least one sensor that has a sensitive area that is arranged inside the ring-shaped permanent magnet and that is configured to measure a change in a magnetic field in the radial direction within a x-y-plane, wherein the x-axis and the y-axis lie orthogonally to the z-axis, respectively.
