Abstract / Hauptanspruch
A device includes a permanent magnetic material extending along a path, a first magnetic angle sensor configured to output at least a first signal and being positioned remotely from the material, and a second magnetic angle sensor configured to output at least one second signal and being positioned remotely from the material and from the first magnetic angle sensor. Based on the at least one first signal and the at least one second signal, a relative positioning of the first magnetic angle sensor and the second magnetic angle sensor with respect to the material in parallel to the path is determined. The magnetization of the material has a periodicity that varies along the path.
