Abstract
The disclosure relates to a magnetic position sensor in at least two directions, the sensor including at least one magnetized element and a probe including at least two magneto-sensitive elements located substantially on the same point and each measuring one of the components of the magnetic field generated by the magnetized element, the magnetized element being movable relative to the magneto-sensitive elements. The probe includes at least one processing circuit capable of carrying out angle and module calculations on the basis of algebraic combinations of the components of the magnetic field and providing at least two independent signals representing the position of the movable element along, respectively, one and the other of the two directions. According to the disclosure, the magnetization vector of the magnetized element is variable in relation to the normal vector on the surface of the magnetized element that is placed opposite the probe in at least one of the dimensions of the magnetized element so as to define a single position of the probe in relation to the magnetized element.
