Abstract
Position identifying transducer using a pair of serially connected magnetoresistive elements with an output terminal at their juncture and which lie in a common plane with the flux-sensitive areas of each element symmetrically disposed about a common center line that is transverse to the direction of motion of the transducer through a variable flux field. This arrangement permits identification of specific locations by providing a peak signal at a predetermined location regardless of the direction of relative motion between the transducer and flux field.
