Product Description:
The RKH0012 is a flexible power-and-signal assembly supplied by Bosch Rexroth Indramat under the RKH Hybrid Cables series. It carries motor phase conductors together with encoder or auxiliary cores in one sheath, allowing linear axes, gantries, and articulated modules to use fewer separate cable runs. Within an automation cell, the cable links a drive controller to a moving load while tolerating continuous motion in cable chains and energy tracks. Combining multiple conductor groups in one jacket also reduces the space required for routing through moving machinery.
The cable has a mechanical life of 5,000,000 bending cycles, allowing it to remain in continuous dynamic service without premature fatigue. Its hybrid design combines power cores, signal pairs, and a protective conductor under collective shielding to reduce crosstalk. During rapid positioning moves, it withstands linear acceleration of up to 30 m/s², making it suitable for high-speed pick-and-place equipment. The maximum track velocity is 4 m/s, which supports continuous movement without placing excessive stress on the insulation system. When the cable flexes in motion, it requires a minimum dynamic bend radius of 10 × D, where D represents the cable’s outer diameter. Maintaining this radius helps preserve conductor geometry and protects the shield from damage during repeated movement.
Each end uses an RHS0011 plug, providing a keyed connection at the drive enclosure and at the motor or sensor junction box. The cable is supplied in the basic configuration, which omits auxiliary drain wires while retaining the overall shielding arrangement and reducing weight in suspended cable chains. For stationary routing where the cable does not move, the minimum permissible bend radius is 5 × D. This tighter fixed-installation radius provides additional routing flexibility inside cabinets and along machine frames without exceeding the cable’s bending limit. The plug arrangement also helps maintain consistent alignment at both connection points, while the combined sheath protects the enclosed power and signal conductors from routine mechanical contact.
