Abstract
Magnetoresistive displacement transducer arrangement for toothed magnetic members in which each transducer is formed by a pair of interconnected sections spaced from each other by the width of a tooth to provide greater change and improved symmetry in the output signal at the tooth edges. Multiple transducers can be positioned interdigitally for compact packaging for vernier type detection of motion. Transducer embodiments for both linear and rotary motion are disclosed.
