RKH0111 by Bosch Rexroth Indramat

The RKH0111 belongs to the RKH Hybrid Cables series manufactured by Bosch Rexroth Indramat. It is a hybrid power-and-signal cable supplied as a finished assembly for motion axes and modular machines where standardized interconnection is required. Within an automation cell, this cable links drives and servo motors while combining power conductors with encoder or auxiliary cores, reducing wiring volume and installation time. Using one assembly for power and feedback also helps keep cable routing more compact around moving axes.

This cable is delivered as a ready-made harness, which eliminates on-site termination and the variability that can come with it. It is a hybrid cable, so the copper power pairs and data pairs share the same jacket while remaining electromagnetically separated. Both ends carry a factory-installed RHS0011 plug connector, allowing direct mating with compatible Indramat components. The matched end terminations keep the assembly ready for direct installation on compatible drive and motor interfaces. Flexing endurance is rated for 5,000,000 bending cycles in an energy-chain environment, which suits continuous-motion gantries and pick-and-place units. During motion, the conductors may follow a dynamic bending radius of 10xD, while static routing inside a cabinet allows a minimum bend radius of 5xD. These bend limits support guide-trough routing and help prevent copper fatigue or shield rupture.

Thermal limits include a maximum conductor temperature of 80 °C and a minimum operating temperature of -40 °C, allowing use near warm drive heat sinks as well as in unheated warehouses. The cable's internal layout is the basic model, so it uses a straightforward core arrangement without extra coolant channels or brake-pair cores. This temperature range suits drag-chain runs, outdoor conveyor links, and tilt-axis routing on articulated robots. It also supports routing through enclosures, machine bases, and moving carriers across mixed temperature conditions.
