Overview

RLB is a PCB level incremental encoder sensor system consisting of a PCB sensor and a magnetic scale or a ring. It has been designed for embedded motion control applications as a position control loop feedback element in space constraint applications.

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 A, B, Z (RS422)
  • Unique or periodic bidirectional index impulse
  • Resolutions up to 622,592 cpr for rotary applications (76 pole ring)

Benefits

  • Miniature design
  • High speed operation
  • RoHS compliant
