1 RMB0D01_1 Issue 1, 6 th October 016 RMB0 Onxis TM magnetic encoder module The RMB0 encoder module provides the functionality of the RM encoder in a compact component format for simple customer integration. With a PCB diameter of only 0 mm the module fits into miniature designs. 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, commutation and linear formats. The RMB0 can be designed into equipment used in a wide range of applications including marine, medical, print, converting, industrial automation, motor control and instrumentation. Product range RMB0C/BC nalogue sinusoidal outputs with a single sine/cosine period per revolution. RMB0IC Incremental with 80 to,048 pulses per revolution (30 to 8,19 counts per revolution with x4 evaluation). RMB0PC bsolute parallel interface with 51 positions per revolution (9 bit). RMB0SC Synchro serial interface (SSI) with 30 to 8,19 positions per revolution. RMB0Vx Linear voltage output in a range of variants. 0 mm diameter circular module 5 V power supply High speed operation to 60,000 rpm bsolute - to 13 bit resolution (8,19 counts per revolution) Industry standard absolute, incremental, analogue, commutation and linear output formats ccuracy to ±0.5 RoHS compliant (lead free) - see Declaration of conformity

The linear output voltage swing ranges from 0 V and (5 V). The number of periods within one revolution (N period ) can be 1,, 4 or 8, representing one full swing over an angle (φ period ) of 360, 180, 90 or 45 respectively. The signal is made up of steps which represent the angular movement needed to register a change in the position (φ step ) and the resulting change in the output voltage (V step ). The number of steps in one period (N step ) is given in the table below. For clockwise rotation of the magnetic actuator, the output voltage increases. For counterclockwise rotation, the output voltage decreases.
