Abstract (en)
[origin: WO2015128592A1] The invention relates to a magnetic sensor for determining the position along a displacement trajectory (T), between a target (2) and a measurement system (3) for measuring the amplitude of the magnetic field created or modified by the target. The sensor comprises: - a system for creating a magnetic field according to a direction (M) perpendicular to the displacement trajectory (T) and with an intensity varying according to a parabolic law, - a measurement system (3) comprising at least two measurement elements (3a), (3b) spatially offset from one another and sensitive to the amplitude of the magnetic field along a given direction, - a processing circuit able to carry out a differential processing of the signals delivered by the measurement elements so as to obtain a linear variation signal giving the position of the target along the displacement trajectory.
