Abstract
A magnetic linear sensor arrangement for detecting the position of a component that can be moved along a predefined movement path includes a device disposed along the movement path for generating a magnetic field whose polarity changes along the movement path of the component, and at least one galvanomagnetic detector with at least two measurement fields, which is arranged within the effective region of the magnetic field. The detector can be moved relative to the magnetic field along the movement path of the component. The galvanomagnetic detector is a Hall sensor which is designed to measure the magnetic field spatially or in at least two directions within a plane. The Hall sensor is provided with at least two measurement fields which are rotationally offset and perpendicular to each other in a corresponding plane.
