RM22 non-contact 5 V
The RM22 is a compact, high-speed rotary magnetic encoder designed for use in harsh environments.
Overview
Introduction
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 give the required output format.
The encoder chip processes the signals received to provide resolutions to 13 bit (8192 positions per revolution) with operational speeds to 30,000 rpm. Output signals are provided in industry standard absolute, incremental or analogue formats.
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.
