RM36 Incremental Rotary Encoder

Stout, resistant to vibrations and shocks, and easy to mount


RM36 - Magnetic encoders

  • RM36: 9-12 bits
  • Single turn incremental/absolute encoder
  • 24Vdc or 5 Vdc supply
  • Excellent immunity to IP68
  • 36 mm diameter body
  • Accuracy: ± 0.3°

The RM36 is a high-speed magnetic rotary encoder designed for use in harsh industrial environments. The non-contact two-part design removes the need for seals or bearings ensuring long-term reliability and simple installation.

The encoder comprises a magnetic actuator andf a seperate encoder body. Rotation of the magnetic actuator is sensed by a custom encoder chip within the body and processed to the required output.

The encoder chip processes the signals received to provide resolutions to 12 bit (4096 positions per resolution) with operational speeds to 30,000 rpm. Resolution options include binary and decimal. Output signals are provided in industry standard absolute, incremental or linear formats.

The compact encoder body is 36mm in diameter and provides dirt immunity to IP68. The RM36 can be used in a wide range of applications, including marine, medical, print, converting, industrial automation, metal working, motor control and instrumentation.
