ABSTRACT:
A magnetic coding arrangement (43) has a holder (11) in which small disk-shaped magnets (14) are mounted in bores (25). The magnets have different polarization (N, S) on their end faces. The diameter (D) of the magnets is slightly less than the diameter of the bores, so that the magnets can swing round freely in the bores where an outer magnetic field acts on them. Each magnet is retained in a particular end position by a soft-magnetic contact (20.1) which consists of a layer of soft-magnetic powder.
Magnetic coding arrangements of this type are used, for example on workpiece-carriers so that these can be provided with the code of a workplace.
