摘要： This invention relates to a contactless magnetic sensor for detecting a linear or angular position, comprising a moveable ferromagnetic element (1) the position of which is detected, and a stator assembly (2) itself comprising two ferromagnetic parts (3, 4), defining with the moveable ferromagnetic element (1) two respective air gaps (7, 8), a permanent magnet (5) and a magnetosensitive element (6) subjected to a magnetic field that depends on the position of the moveable ferromagnetic element (1) and designed to deliver a measurement signal that depends on the magnetic field to which it is subjected. According to the invention, the two ferromagnetic parts (3, 4) define there between a third air gap (9), the permanent magnet (5) being rigidly connected only to the first ferromagnetic part (3) and the magnetosensitive element (6) being placed in the third air gap (9).

摘要： The invention relates to a linear electromagnetic actuator that has a stroke c, with at least one stable position in one of the ends of the stroke, and comprises: an armature (6) made of a soft magnetic material, said armature (6) being movable in an axial direction Y and having a length Hm in the direction Y, said armature (6) having a symmetrical shape at the axis Y, and a stationary stator yoke (1) made of a soft magnetic material and holding at least one electric coil (2). Said actuator also comprises at least one stationary permanent magnet (4) that is magnetized along a transverse axis X perpendicular to the direction Y. The magnet (4) is transversely placed between the movable armature (6) and the electric coil (2). The magnet (4) has a length Ha in the direction Y. The stationary yoke (1) and the movable armature (6) define therebetween at least one axial air gap. Ha+c is of the order of magnitude of Hm. The length Hm is such that 0.9 x (Ha+c)
