Abstract

La présente invention a pour objet un capteur d’angle (3) destiné à détecter la position angulaire d’un élément mobile en rotation dans un moteur de véhicule automobile. Le capteur d’angle (3) comporte au moins une sonde magnétique (4) apte à détecter les orientations d’un champ magnétique généré par un aimant (1) fixé sur l’élément mobile. L’aimant (1) présente une face radiale externe (5), une face supérieure (6) et une face inférieure. Selon l’invention, le capteur d’angle (3) comprend une enveloppe magnétique (2) entourant la face radiale externe (5) de l’aimant (1), l’enveloppe magnétique (2) étant composée d’un matériau magnétique. Figure pour l’abrégé : Fig. 1.The present invention relates to an angle sensor (3) for detecting the angular position of a rotating mobile element in a motor vehicle engine. The angle sensor (3) comprises at least one magnetic probe (4) capable of detecting the orientations of a magnetic field generated by a magnet (1) attached to the mobile element. The magnet (1) has an outer radial face (5), an upper face (6) and a lower face. According to the invention, the angle sensor (3) comprises a magnetic envelope (2) surrounding the outer radial face (5) of the magnet (1), the magnetic envelope (2) being made of a magnetic material . Figure for the abstract: Fig. 1.
