Abstract
A sensor for determining an angular position of a rotor comprises an elongated member for attachment to the rotor for lengthwise movement in response to rotation of the rotor. The elongated member has a length and includes indicia identifying predetermined designated segments along the length. A field source generates a field adjacent to a selected portion of the length of the elongated member. A field effect detector detects at least one of the indicia associated with the selected portion of the length of the elongated member in response generation of the field adjacent the selected portion. The detected one of the indicia identifies at least one of the designated segments. The identified designated segment is functionally related to the angular position of the rotor.
