Embodiments relate to apparatus (200) and methods for distinguishing data of a plurality of multidimensional magnetic field sensors (120). A first sensor arrangement (100-1) comprises a first magnetic field source (110-1) and a first multidimensional magnetic field sensor (120-1), wherein the first magnetic field source and the first magnetic field sensor are arranged relative to one another in a first manner characteristic for the first sensor arrangement. At least one second sensor arrangement (100-2) comprises a second magnetic field source (110-2) and a second multidimensional magnetic field sensor (120-2), wherein the second magnetic field source and the second magnetic field sensor are arranged relative to one another in a second manner characteristic for the second sensor arrangement.
