Overview

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.

Features

  • Miniature design
  • Unique or periodic bidirectional reference mark
  • Incremental ABZ TTL or RS422, BiSS C or SSI output
  • Suitable for use with linear scales, radial and axial rings

Benefits

  • High system accuracy up to ±10 μm
  • High-speed operation
  • Non-contact and wear-free measuring principle
  • Pin or flexible cable option
