Abstract
A magnetic-based sensor is disclosed which can detect a linear and rotary position of a shaft whose movement is to be measured. Such sensor can operate to yield linear displacement as well as rotation. A position magnet is mounted on the shaft for measuring linear motion. A spirally wound magnet is mounted on the shaft to detect rotational motion. Both of such motions are detected by a single magnetic-based sensor.
