RMF44 rotary magnetic module on metal flange

More Views

The RMF44 is a compact encoder module designed for easy installation with a self aligning metal mounting flange. The low cost module can be provided with an integrated connector.

The encoder module consists of a magnetic actuator and a separate sensor board. Rotation of the magnetic actuator is sensed by a custom encoder chip mounted on the sensor board, and processed to give the required output format. Output signals are provided in industry standard absolute, incremental, analogue or linear formats.

The RMF44 can be used in a wide range of applications including motor control and industrial automation.
