More Views

The RMB28 encoder module is designed for direct integration to high volume OEM applications. The low cost 28 mm square PCB can also be provided with a connector for easy installation.

 

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 RMB28 can be used in a wide range of applications including motor control and industrial automation.
