ABSTRACT:
A sensor head for a magnetic flux transmitter is disclosed which permits the manufacture, in series, and a simple mutual alignment, of a sleeve-shaped permanent magnet and, of a Hall generator which is disposed within the permanent magnet. An embodiment is disclosed which provides the disposition of the Hall generator at the end of a finger-shaped extension of a printed circuit board and to allocate a clamping piece, which is pressable into the permanent magnet, to the carrier. The permanent magnet is displaceable, relative to the Hall generator, for the adjustment of an optimum working point of the magnetic flux transmitter. The permanent magnet, however, has a sufficiently tight seating upon the carrier up to the final attachment of the components of the sensor head by means of an adhesive compound.
