Overview

The LM13 is a contactless high-speed linear magnetic system designed for linear or rotary motion sensing in harsh environments.

The system consists of a compact readhead and a separate selfadhesive magnetic scale or ring.

Features

  • Resolutions from 1,280 to 327,680 counts per revolution
  • High speed operation to 20,000 revolutions per minute
  • Integral set-up LED

Benefits

  • Compact readhead
  • Excellent dirt immunity
  • High reliability from proven non-contact sensing technology
  • Industry standard digital and analogue outputs
