Overview
RoLin™ is a component level encoder consisting of a RLM readhead and a magnetic scale or ring. It has been designed for embedded motion control applications as a position control loop element.
The information carrier is a periodically magnetised scale with a pole length of 2 mm. Radial or axial reading of the ring is possible.
