RM36 rotary magnetic modular encoder

More Views

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 and a separate 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 13 bit (8192 positions per revolution) 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 just 36 mm 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.
