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.

Features

  • Incremental quadrature
  • TTL output signals A, B and index Z
  • Resolutions from 125 µm to 0.244 µm

Benefits

  • High speed operation
  • Bi-directional reference mark
  • High reliability from proven non-contact sensing technology
  • Pin / Flex options
  • RoHS compliant
