ABSTRACT:
A magnetic position sensor system including a magnetic medium divided into a plurality of areas of magnetization for producing a magnetic field with a variable intensity. The magnetic medium includes a first side, a second side and a longitudinal axis. A Hall cell is used for detecting the intensity of the magnetic field produced by the magnetic medium and for producing an electric signal which corresponds to the intensity detected. The magnetic medium is movable with respect to the Hall cell so that the Hall cell scans along the first side of the medium along the longitudinal axis and detects the intensity of the magnetic field at any given point along the longitudinal axis of the medium.
