Magnet sensor and ferromagnetic poles

A magnetic position sensor comprising:

• a magnetized structure, including a permanent magnet producing a magnetic field and a support made of soft ferromagnetic material wherein the magnet is embedded, the support having two pole shoes located on either side of the magnet;
• at least one magnetically sensitive element configured to move relative to the magnet along a measurement path;
• wherein the magnet and the two pole shoes respectively have front surfaces all located opposite the at least one magnetically sensitive element during the movement along the measurement path;
• wherein during movement along the measurement path, the front surfaces are successively located opposite the sensitive element;
• and wherein a ratio between:
• the minimum distance between the front surface of the magnet and the center of the magnetically sensitive element, and
• minimum distance between one or the other of the front surfaces of the pole shoes and a center of the magnetically sensitive element is between 0.7 and 1.3;
• and
• wherein a sum of lengths of the front surfaces of the pole shoes, along the measurement path, is greater than or equal to a length of the front surface of the magnet.
