Abstract
A printwheel encoder comprises a non-ferrous shaft having a magnet strip and a flexible Hall-effect sensor arrangement affixed thereon. Molded printwheels including a flux conducting ring having an inner spiral surface are rotatably mounted on the shaft in respective juxtaposition to each Hall-effect sensor. The wheels are mounted adjacent to each other so that the rings form a nearly continuous flux conducting sheath which protects the Hall-effect sensors from external magnetic fields.
