Abstract: A rotary sensor (10) includes a rotating portion (12) having an outside surface (28) and a magnetic pattern (16) magnetically printed on the rotating portion (12). One or more hall-effect switches (32) are located adjacent to the magnetic pattern (16) and a magnetic field of at least a portion of the magnetic pattern actuates the switches (32). Rotation of a driveshaft (18) controls electric signals conducted through the switches (32) indicating the angular position of the driveshaft (18).
