ABSTRACT:
In a magnetic position measuring device for determining the relative position of two objects which can be moved with respect to each other, a magnetic graduation is scanned by at least two Hall elements for the generation of position-dependent output signals. The Hall elements respectively have at least one supply voltage and one measuring voltage connector. Furthermore, at least one switching unit is provided, which periodically interchanges the supply voltage and the measuring voltage connectors of each Hall element with each other. The periodic interchange of the supply voltage and measuring voltage connectors of the various Hall elements with each other is furthermore synchronized by means of at least one synchronization unit.
