HALL EFFECT BASED ANGULAR POSITION SENSOR

摘要

A magnetic rotational position sensor (20) has a single magnet (40) mounted on a rotating turret (30) that rotates on a housing (22) that is mounted about a fixed ball stud (52). The turret (30) is arranged to rotate in a first plane around the ball stud (52). A magnetic field orientation sensor (42) is mounted to the housing (22), such that the magnet (40) is moved along an arc tangent to the Hall effect sensor. The ball (54) of the ball stud (52) forms one half of a universal joint, the other half being formed by a shaft termination (32) that is mounted to rotate with the turret (30), and also mounted for rotation in a second plane perpendicular to the first plane of the turret.
