RKH0012 by Bosch Rexroth Indramat

The RKH0012 cable assembly is part of the RKH Hybrid Cables series. It is a pre-terminated hybrid lead that combines power cores with data pairs inside a single jacket, reducing the number of separate lines that must be guided through an energy chain. Within industrial automation, the cable links moving actuators or spindle drives to their control hardware, supplying energy and feedback while tolerating continuous motion in multi-shift production environments. Using one cable instead of separate motor and feedback leads also helps reduce track fill and keeps routing simpler in compact machine layouts.

The mechanical life is rated for 5,000,000 bending cycles, meaning it can flex this many times before conductor fatigue is expected. During dynamic motion, the sheath may curve around a minimum radius of 10xD, protecting the internal conductors from excessive strain, while fixed routing permits a tighter radius of 5xD. Linear modules that accelerate sharply are supported because the cable withstands up to 30 m/s² without jacket tearing or internal wire migration. High-speed carriers are also accommodated, as a maximum travel velocity of 4 m/s is permitted without compromising signal integrity or causing excessive heat buildup. This combination of bend radius, acceleration tolerance, and travel speed suits transfer units, robotic slides, and other continuously cycling axes.

Functionally, the product is a Hybrid cable, so one run handles both servo power and encoder communication and leaves more room inside cable tracks. Each end is fitted with an RHS0011 Plug, which allows direct connection at both mating points and helps keep installation straightforward. That arrangement can reduce the number of separate connections at the moving axis. This variant uses the Basic design, indicating a standard outer jacket and shielding scheme suitable for typical factory environments. Manufactured by Bosch Rexroth Indramat, the assembly uses consistent connector pinouts across the series.
