Product Description:

The RG2-002ABT is an encoder cable produced by Bosch Rexroth Indramat as part of the RG2 Encoder Cables series. It carries position feedback signals between a motor-mounted sensor and the drive controller within industrial automation. The cable’s electrical conductors and mechanical sheath are designed for dynamic routing inside energy chains and robotic joints where constant bending occurs. In motion axes that rely on analog encoder feedback, RG2-002ABT helps maintain deterministic communication and accurate closed-loop control.

The cable employs a torsion design that permits continuous rotation of ±180° per meter, reducing conductor fatigue in swivel applications. This is the 2nd generation of Rexroth feedback cabling, meaning the conductor geometry and shielding were updated to match newer servo drives. A rugged PUR (Orange RAL 2003) outer sheath resists hydraulic oil and weld spatter while maintaining flexibility at low temperatures. Signal pairs are matched to the Hiperface interface, so sine-cosine channels and digital data share the same bundle without crosstalk. Insulation keeps leakage low; resistance is at least 20 MΩ/km, limiting capacitive loading over long runs.

For fixed installation the sheath may be routed around curves with a minimum radius of 5×D, while dynamic drag-chain movement requires 7.5×D to avoid jacket cracking. The circular geometry measures 8.5 mm across, allowing standard energy-chain inserts and M17 backshell glands. Both power and differential signal pairs are rated to 300 V, so one cable can handle encoder supply and reference channels under the same insulation class. An M17 motor plug is factory terminated to simplify field wiring, and the analog pair supports AS/AM and BS/BM transducers, ensuring compatibility with legacy motors that still rely on amplitude-modulated feedback.
