Title
(EN) NON-CONTACT ANGLE SENSOR
(FR) CAPTEUR D'ANGLE SANS CONTACT
(JA) 非接触式角度センサ
Abstract
(EN)
A non-contact angle sensor provided with an automatic return mechanism, configured in such a manner that a rotating shaft (33) is affixed to the center of rotation of a rotor (40) housed within a case (20), the intermediate section of the rotating shaft is inserted through and supported by an annular bearing (31), a coiled spring (35) through which the rotating shaft is inserted within the case presses the rotor relative to the case to a neutral angle position, a magnet (34) is affixed to the rear surface of the rotor so as to be separated outward in the radial direction from the rotating shaft, a magnetic sensor (53) is provided on a circuit board (50), which is provided within the case so as to face the rear surface of the rotor, so as to be separated outward in the radial direction from the rotating shaft and so as to face the magnet at an interval, and a bearing end (33b) of the rotating shaft (33) is supported by a bearing hole (62a) formed in the inner wall of a cover (62) for closing the case from behind the circuit board.

L'invention concerne un capteur d'angle sans contact doté d'un mécanisme de retour automatique. Le capteur d'angle sans contact comprend un bras rotatif (33) fixé sur le centre de rotation d'un rotor (40) logé dans un boîtier (20), la section intermédiaire du bras rotatif étant insérée dans un palier annulaire (31) et supportée par ce dernier. Un ressort enroulé (35) dans lequel le bras rotatif est inséré au sein du boîtier presse le rotor par rapport au boîtier vers une position d'angle neutre. Un aimant (34) est fixé sur la face arrière du rotor et est séparé du bras rotatif vers l'extérieur dans le sens radial; et un capteur magnétique (53) est monté sur une carte de circuit imprimé (50), se trouvant dans le boîtier et en face de la surface arrière du rotor, afin d'être séparé du bras rotatif vers l'extérieur dans le sens radial et de se trouver en face de l'aimant à une certaine distance. Une extrémité d'appui (33b) du bras rotatif (33) est supportée par un orifice d'appui (62a) formé dans la paroi interne d'un couvercle (62) servant à fermer le boîtier par l'arrière de la carte de circuit imprimé.
