摘要： A magnetic sensor includes first and second members movable relative to each other. One of the members is secured to a movable member and the other fixed. The first member defines a magnetic circuit with an air gap provided with a detector sensitive to the magnetic induction prevailing in the air gap. The second member is a permanent magnet in magnetic coupling relation with the first member. The first member has a tubular portion and a rod-shaped portion, the portions being magnetically coupled, at one end, by the permanent magnet with radial magnetization and, at the other end, by elements for concentrating the magnetic flux in the air gap. The air gap is delimited by these concentration elements and the facing end of the rod-shaped portion of the first member.
