1 Data sheet RMB30D01_08 Issue 8, 14 th January 2009 RMB30 angular magnetic encoder module The RMB30 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 RMB30 can be used in a wide range of applications including marine, medical, print, converting, industrial automation, metal working, motor control and instrumentation. RMB30I - Incremental output, Push- Pull, 24 V RMB30IB - Incremental output, Open Collector NPN, 24 V RMB30IC - Incremental with 80 to 2,048 pulses per revolution (320 to 8,192 counts per revolution with x 4 evaluation), 5 V RMB30SC - Synchro serial interface (SSI) with 320 to 8,192 positions per revolution, 5 V RMB30SI - Synchro serial interface (SSI) and incremental outputs, 5 V RMB30C - Linear current output in a range of variants, 24 V RMB30V - Linear voltage output in a range of variants, 24 V 30 mm diameter circular module 24 V and 5 V power supply versions High speed operation to 30,000 rpm bsolute - to 13 bit resolution (8,192 counts per revolution) Industry standard absolute, incremental, analogue and linear output formats ccuracy to ±0.5 RoHS compliant (lead free) associate company

However, pins 1, 2 and 3 have been provided to allow easy connection to a 3 terminal regulator to generate 5 V from 24 V. Pin 2 () is connected on the PCB to pin 5 (), and pin 6 ( ) is connected via a diode on the board to pin 3, for reverse voltage protection. NOTE 2: The SMD regulator supplied on these boards limits the supply voltage ( ) to 12 V ( = 8 V to 12 V). If operation is required at 24 V supply, then this regulator must be replaced by a more powerful off-board device (TO220 package) mounted to a suitable heatsink. associate company 7
