RG2-003AAB by Bosch Rexroth Indramat

The RG2-003AAB is an encoder cable produced by Bosch Rexroth Indramat within the RG2 Encoder Cables series. It connects MS2x servo motors to compatible drive controllers and transfers encoder feedback so the control loop can correct torque and speed in real time. The cable is intended for moving-axis installations where repeated flexing and compact routing are common. This makes it suitable for servo axes that reverse direction often and still require stable encoder communication.

The cable is rated for 5,000,000 flex cycles, indicating how many dynamic bends the jacket and conductors can withstand before fatigue becomes a concern. Its conductor cross-section is 0.50 mm², which supports encoder-related signal transmission with controlled resistance. During motion, the assembly requires a minimum bending radius of 7.5xD, while fixed routing can be formed down to 5xD. A controlled bend radius helps protect the shield and conductor geometry during cable-chain travel. Signal transmission is carried through an integrated M17 Encoder Connector, which mates with the motor encoder port and locks with a threaded coupling. The connector also helps maintain a secure interface where machine vibration is present.

The cable is a 2nd Generation product in the line and uses updated insulation materials that reduce capacitance and improve resistance to electromagnetic interference. Its internal wiring uses a Double Cable layout that separates the encoder electronics supply conductors from the differential feedback channels. This layout helps preserve signal quality when the cable is routed near other machine wiring. Data transmission uses Digital Cable signaling, so the shield and impedance are arranged for fast serial feedback. Compatibility is limited to MS2x motors, so the connector format and signal arrangement match that motor family.
