Product Description:
The RKH0121 hybrid cable is engineered by Bosch Rexroth Indramat for the RKH Hybrid Cables series. Serving as a single run that carries motor power and encoder signals, it reduces cabinet congestion and supports moving axes in automated tooling systems.
In continuous motion, the cable withstands 5,000,000 bending cycles, a figure tied to high-flex PUR jacketing that resists metal fatigue. It is supplied as a Ready-Made assembly so installation only involves routing and tightening the plugs. Each end terminates with an RHS0021 circular connector that locks with a bayonet quarter-turn for vibration resistance. Dynamic chain routing is permitted down to a radius of 8xD, preventing copper strand damage during rapid axis strokes. Rated operation spans -40 to +80 C, allowing the assembly to move beside machines that cycle between refrigerated and heated zones.
When a machine is parked, the static routing limit lowers further to 4xD, which simplifies panel layout inside tight troughs. The conductor bundle follows the Hybrid architecture, meaning power cores and fibre-optic feedback pairs share the same shield layer formed around the REH0803 inner cable. This shielding scheme improves EMC immunity while keeping outer diameter small in the Basic model variant, which omits additional brake pairs to save weight. Identical storage and transport temperatures of -40 to +80 C ensure the jacket remains flexible after long warehouse periods before commissioning.
Wake Industrial stocks this cable and, for urgent retrofits, same-day shipping is available on qualifying orders. Customers receive a 1-year warranty that covers workmanship and material defects. Furthermore, any quotation issued for the RKH0121 remains valid for 30 days, assisting maintenance teams in scheduling purchases.
