ABSTRACT:
A position detector providing an electrical position feedback signal proportional to relative mechanical movement between two elements employs a hall effect device to sense changes in magnetic flux density resulting from relative movement of the hall effect device with respect to an adjacent magnetic field, the hall effect device producing an electrical signal proportional to magnetic flux density which signal comprises the electrical position feedback signal. The hall effect device and magnet are supported in respective relatively movable members in cooperative relationship such that the magnet is adjacent the hall effect device so as to permit relative movement of the hall effect device with respect to the magnetic field, the members being preferably adapted for mounting respectively on two relatively movable mechanical elements.
