Overview

The RM22 is a compact, high-speed rotary magnetic encoder designed for use in harsh environments. The non-contact two part design removes the need for seals or bearings ensuring long-term reliability and simple installation.


The compact encoder body is just 22 mm in diameter and provides dirt immunity to IP68. The RM22 can be used in a wide range of applications including marine, medical, print, converting, industrial automation, metal working, motor control and instrumentation.

Features

  • High speed operation to 30,000 rpm
  • Absolute - to 13 bit (8192 counts per revolution)
  • Industry standard absolute, incremental and analogue output formats
  • Compact - 22 mm diameter body
  • Accuracy to ±0.5°
  • Power supply 5 V

Benefits

  • Excellent immunity to IP68
  • Non-contact, frictionless design
  • Simple installation
  • RoHS compliant (lead free)
