RM30D01_11 Issue 11, 3 rd March 2017 RM30 angular magnetic encoder module The image does not represent all variants. The RM30 encoder module provides the functionality of the RM36 encoder in a component format for simple customer integration. With a large range of outputs and both 5 V and 24 V power supply variants the unit is easily integrated to existing electronics. 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 RM30 can be used in a wide range of applications including marine, medical, print, converting, industrial automation, metal working, motor control and instrumentation. Product range RM30Cx Linear current output in a range of variants.
