RKH0907 by Bosch Rexroth Indramat

The RKH0907 hybrid cable is manufactured by Bosch Rexroth Indramat as part of the RKH Hybrid Cables series. It carries motor power and encoder feedback through one shielded sheath, which reduces cable volume between the drive and the motor. Used between drive controllers and servo axes, the assembly supports stable signal transmission and consistent power delivery in handling machines, packaging equipment, and articulated robots. Combining both paths in one cable also helps simplify routing through moving carriers and tight machine frames. This arrangement can also reduce the number of cable entry points at the cabinet and motor housing.

The cable is rated for 5,000,000 flex cycles, so it can operate continuously in dynamic drag chains without early mechanical fatigue. Its construction follows the Basic version of the series, so the conductor cross-sections and shielding use the standard layout. As a Ready-Made unit, it comes with factory-installed terminations; the drive end uses connector RHS2322, while the motor side uses RHS0016. The permitted temperature range is -40 °C to 80 °C for service and storage. That range suits both cold machine areas and warm enclosures where cables remain exposed to continuous motion.

This cable uses a single-sheath power and signal variant, which helps keep the overall diameter small enough for multi-axis carrier tracks. Jacket materials and filler spacing help keep conductor lay lengths stable, which supports consistent impedance during repeated flexing. Stable electrical geometry is useful when encoder signals and motor power must share the same moving path without excessive cross-coupling. The combined format also reduces the number of separate cables that must pass through the same routing channel, leaving more room for pneumatic or vacuum lines in compact automation equipment. It is well suited to equipment where repeated bending and limited routing space occur at the same time.
