RG2-002AAB by Bosch Rexroth Indramat

The RG2-002AAB is an encoder cable manufactured by Bosch Rexroth Indramat within the RG2 Encoder Cables series. It serves as the feedback line between a servomotor-mounted sensor and the corresponding drive, transmitting high-resolution position data so the motion controller can correct errors in real time. By combining shielded conductors with a compact outer diameter, the assembly keeps signal noise low while allowing tight routing inside moving cable tracks typical of machining centers, pick-and-place arms, and other automated equipment. This type of cable is suited to axes that reverse direction often, where stable feedback helps the drive maintain accurate motion.

Its mechanical profile starts with a cable design classified as Basic, meaning the jacket and insulation follow the standard geometry used for this family. The individual cores have a cross section of 0.50 mm², balancing current capacity with flexibility in moving or fixed routing. Continuous movement is supported when the dynamic bending radius is held to 7.5 × D, while stationary runs may bend to a tighter 5 × D. The cable remains functional in ambient temperatures from -40 to +80 °C, and the same range applies during storage. These characteristics support reliable routing through compact machine spaces where the feedback lead must bend repeatedly without taking up excessive room.

Long service life is supported by a rated endurance of 5,000,000 flex cycles, which suits highly dynamic axes and repetitive motion patterns. The cable belongs to the second generation of the RG2 platform, which uses improved shielding for cleaner feedback at higher clock rates. Feedback data follow a digital protocol, allowing the assembly to work with compatible servo systems that use electronic encoder communication. At the motor end, an integrated M17 encoder connector provides a sealed interface, and the direct connection to the drive reduces extra connection points that can affect signal quality.
