<p>The disclosure relates to a contactless magnetic sensor for measuring the angular or linear movement of a ferromagnetic target. The purpose of the disclosure is to make a position sensor having reduced dimensions and capable of detecting a piece of position information as soon as the sensor is powered without degrading the performance thereof. To this end, the disclosure relates to a mobile sensor that includes at least one permanent magnet, at least one ferromagnetic member at least one magnetically sensitive member, the permanent magnet having an upper surface opposite the ferromagnetic target, wherein the permanent magnet has a substantially cylindrical or parallelepiped shape and includes a cavity, the ferromagnetic member being arranged inside the cavity and the magnetically sensitive member being arranged inside the cavity above the ferromagnetic member and below the upper surface of the magnet.</p> |
