Product Description:
The RHB2-011BAB is manufactured by Bosch Rexroth Indramat for the RHB2 Encoder Cables series. It serves as a combined power-and-signal link between MS2 synchronous motors and ctrlX DRIVE inverters. Classified as a Rexroth cable, it can be routed through machine energy chains to carry encoder feedback and motor current in one sheath, removing the need for separate motor and sensor cables in industrial automation systems. This arrangement also reduces the number of individual cables that must move through a carrier during repeated machine cycles.
This model is a hybrid cable that terminates at the motor end with an M17 hybrid connector. The connector mates directly with the device housing, enabling a motor-to-drive connection without an intermediate junction. Internally, the conductors use 18 AWG stranding with a cross-sectional area of 0.75 mm², providing a continuous current-carrying capacity of 10.4 A RMS for the motor supply. The flex-rated construction has a service life of 5,000,000 bending cycles, and its insulation materials retain their shape during repeated movement through cable carriers. Under dynamic movement, the cable supports a minimum bending radius of 7.5 times its outer diameter. Stationary installations permit a tighter bending radius of 5 × D. The basic design does not include additional shielding or coolant ducts, which helps maintain a compact outer diameter for drag-chain layouts.
The cable operates from -40 °C up to 80 °C, and the same temperature range applies during storage. This range permits the cable to operate in cold industrial areas as well as locations exposed to elevated machine temperatures. Its jacket supports repeated flexing while protecting the internal power and feedback conductors from mechanical wear. The direct connection eliminates the need for terminal boxes between the motor and drive. Its MS2(x) interface carries encoder signals at the impedance required by compatible Rexroth motor feedback circuits.
