Abstract
A non-volatile, absolute rotation sensor employs a radial guide and spiral guide rotating with respect to each other to move a marker element continuously along the radial guide so that a distance of the marker element along the radial guide provides an indication of shaft movement over multiple turns. A sensor system senses the distance of the marker element along the radial guide to provide an electric output.
