A non-contact absolute encoder for determining the absolute position of a movable workpiece includes a movable transducer element adapted to be coupled to the workpiece, and a sensor positioned proximate the transducer element. The encoder may be of either the rotary or linear type. The transducer element includes a characteristic profile that varies substantially continuously as a function of the transducer position. The characteristic profile may be magnetic, optical, or some other characteristic that is measurable by a non-contact sensor and is representative of transducer position.
