RKH0211 by Bosch Rexroth Indramat

The RKH0211 cable is a pre-terminated hybrid connection produced by Bosch Rexroth Indramat for the RKH Hybrid Cables series. By combining motor power cores with digital signal pairs inside one sheath, it reduces the number of routed lines and helps simplify dress-pack layout on moving axes. This product is intended for continuously flexing machine modules such as gantry robots, pick-and-place heads, and linear transfer systems where compact wiring and long service life are required. The hybrid layout also helps keep cable routing cleaner in areas where separate power and feedback leads would take up more space.

This assembly is supplied as a ready-made unit, which avoids field crimping and reduces variation from manual termination. The jacket and conductor bundle are rated for 5,000,000 cycles of dynamic motion, supporting high-duty applications with repeated travel. During movement, the cable may bend to a radius as small as 10 × D without exceeding its intended mechanical limit. Reliable operation is supported at temperatures down to -40 °C and up to 80 °C, allowing use in both cold areas and warmer cabinet spaces. Both ends use keyed circular connectors that help prevent reverse mating and support consistent shielding transfer through the connection path.

For fixed routing in trays or control panels, the minimum permitted curvature is 5 × D, which helps with compact enclosure layouts. Each end uses a multi-pin RHS0011 connector that combines power, feedback, and protective conductor contacts in one plug. The cable is classified as a Hybrid Cable, so it carries different conductor functions within a single assembly instead of using separate cords. Its Basic design designation indicates the standard outer jacket and braid arrangement for general-purpose drag-chain use. This format keeps the connection scheme straightforward while preserving the combined power and signal concept of the cable.
