Abstract: The disclosure relates in particular to a method for parameterizing a system for measuring an absolute position, the system including a permanent magnet, at least one probe that is mobile relative to the magnet over a given path, and a controller providing position information calculated on the basis of the arctangent of the ratio, wherein a correction coefficient G is assigned, between the output signals of the probe, wherein the signals are pseudo-sinusoidal and squared. The method includes an optimization operation that involves selecting the value of the coefficient G that minimizes the errors of the measurement system resulting from the pseudo-sinusoidal character of the signals output from the probe.

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.

Abstract: The invention relates to an angular or linear magnetic position sensor that comprises a mobile member including at least one magnet (1) having a magnetization direction that varies linearly along the movement direction of the magnet in a surface defined by said movement direction and in a normal direction, at least four magneto-sensitive elements (2, 3 and 4, 5) and at least one processing circuit (6) providing a signal based on the absolute position of the mobile member, characterized in that a first set of magneto-sensitive elements (2, 3) and (4, 5) are located at a same point, the first couple of magneto-sensitive elements (2, 3) being spatially offset from a second couple of magneto-sensitive elements (4, 5) along the movement direction, and in that the magneto-sensitive elements (3 and 5) measure the tangential component of the magnetic field while the magneto-sensitive elements (2 and 4) measure the normal component of the magnetic field in order to provide, after algebraic combination of the component
