Abstract

608672 A non-contact angle sensor provided with an automatic return mechanism is disclosed. The sensor is configured in such a manner that a rotating shaft (33) is affixed to the centre of rotation of a rotor (40) which is 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 , outward in the radial direction from the rotating shaft. A magnetic sensor (53) is provided on a circuit board (50 – Fig 2a) to face the rear surface of the rotor and so the magnet. A bearing end (33b) of the rotating shaft (33) is supported by a bearing hole (62a – Fig 2a) formed in the inner wall of a cover (62) for closing the case behind the circuit board. This arrangement minimises wear caused by friction between the rotating shaft and the bearing due to long-term use and prevents increases in angular run-out of the rotating shaft increasing durability of the angular sensor.
