Product Description:
The RKL4308 is a ready-made motor power cable manufactured by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It serves as the pre-assembled link between a drive controller and its motor in automated cells, conveying three-phase power and auxiliary conductors without manual terminations. A polyurethane outer sheath and molded connectors allow the cable to operate inside dynamic cable carriers, robotic joints, and other motion axes found in industrial automation.
Mechanical durability is demonstrated by its ability to survive 5,000,000 bending cycles, making it suitable for continuous-flex loops. Installers can route the assembly to a minimum arc of 7.5 × D dynamic bend radius without overstressing conductors. The outer sheath uses PUR jacket material, giving high resistance to oils, coolants, and abrasion. Electrically, line-to-line capacitance is limited to 0.7 nF/m, which minimizes reactive current drawn from high-frequency inverters, and copper losses are contained by a 7.98 Ω/km conductor resistance value that keeps voltage drop within drive limits.
The core is manufactured from INK0602 bulk stock, pairing a 2.5 mm² power path with a 1.0 mm² control conductor cross-section for sensors or brake release. A keyed RLS0722/K03 connector mates with the controller, while the motor terminates through a sealed RLS1201/C04 plug that locks without tools. Together with its RAL 2003 orange sheath and compatibility with drag-chain installation, these interfaces shorten field replacement time and maintain clear circuit identification inside machinery enclosures.
