RKH0441 by Bosch Rexroth Indramat

The RKH0441 is a cable assembly produced by Bosch Rexroth Indramat for the RKH Hybrid Cables series. It combines power and signal conductors inside a single jacket, so one routed line can serve functions that might otherwise require separate cables. This layout helps reduce the number of cable runs in moving assemblies and keeps routing more compact around motor and control connections. The assembly is supplied with connectors already attached, which provides a direct-fit connection for automated machinery.

An assembly type marked as Ready-Made means the cable arrives cut to length with both connectors attached, avoiding field crimping. The designation Hybrid shows that power and data pairs share the same sheath, which helps reduce cable tray space. On the device side, connector 1 is the keyed RHS0015, and this molded plug helps prevent polarity reversal while staying locked during dynamic movement. Repetitive motion requires a minimum dynamic bend radius of 10 × D, and continuous operation is allowed up to 80 °C so the jacket and insulation remain stable near motors or drives that radiate heat.

Durability for moving applications is shown by a flex life of 5,000,000 bending cycles, which suits repeated motion on pick-and-place arms or gantries. The variant code marked Basic identifies a standard outer jacket without additional EMC layers, which helps keep the cable lighter where extra shielding is unnecessary. Connector 2 is the panel-mount RHS0024, giving a sealed transition to control cabinets. When the machine is at rest, the cable may be folded to a static bend radius of 5 × D, reducing stress when the conductors are not repeatedly flexed. With a minimum service temperature of -40 °C, the cable can be used in unheated warehouses or on outdoor equipment during cold-weather startup.
