RLM

Miniature Incremental Magnetic Encoder

RLM is a component-level encoder system consisting of a RLM readhead and a magnetic scale or ring. It is designed as a position control loop element for embedded motion control applications. The encoder also has a self-diagnostic function for error detection.
