Product Description:
The RHB2-023DCB cable is manufactured by Bosch Rexroth Indramat as part of the RHB2 Encoder Cables series. Classified as a Rexroth hybrid cable, it combines motor power and encoder feedback in one sheath and is intended to link MS2(x) servo motors to ctrlX DRIVE controllers in flexible automation cells. Its role is to reduce wiring volume and to maintain synchronized position data while the axes move continuously.
Within this second-generation basic design the emphasis is durability and predictable electrical performance. The jacket, shielding and fillers survive 5,000,000 bending cycles in energy-chain service, allowing the cable to follow gantry and robotic motions for years. Copper conductors use a standardized cross-section of 1.5 mm²; four such cores are grouped as 4x 1.5 mm² to carry phase and neutral paths. At 40 °C those cores can deliver up to 15.6 A continuously without exceeding permitted temperature rise. Separate pairs provide encoder and control channels, and the hybrid layout, together with the shielding concept, limits electromagnetic coupling so feedback accuracy is maintained even during high current transients under continuous duty cycles.
Installation clearances dictate minimum bend radii: during motion the cable may curve to 7.5xD, while once fixed it can rest at 5xD. The feedback bundle uses 4x AWG24 conductors, supplemented by 2x 0.5 mm² signal lines for auxiliary functions. Service is guaranteed from -40 °C up to 80 °C, and the same interval applies when the cable is stored. These thermal bounds, together with the corrosion-resistant jacket and the basic construction concept, permit deployment in cold-start machinery or near warm process zones without performance loss.
