Product Description:
The RKL4584 is a motor power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It supplies three-phase power and auxiliary control signals between an Indramat drive and its motor in industrial automation cells. The hybrid layout allows the same sheath to carry power conductors and brake leads, reducing cabinet wiring and ensuring EMC compliance in moving gantry, robot, and linear axis applications. Its PUR jacket and drag-chain rating make it suitable for continuous flex applications inside dynamic machine frames.
The cable core is arranged as 4x16.0 mm² + 2x(2x1.5 mm²)StC, placing four power conductors and two shielded control pairs in one sheath. Each power core has a cross-section of 16.0 mm², limiting voltage drop, and each control pair measures 1.5 mm² for brake or sensor leads. At 20 °C the copper shows a conductor resistance of 1.21 Ω/km, and the typical mutual capacitance is 1.2 nF/m, so drive signals remain clean over long routes. A matte, adhesion-free PUR jacket in RAL 2003 orange resists oils and weld spatter, and the assembly is qualified for drag-chain use.
Dynamic motion capability is defined by a service life of 5,000,000 flex cycles in drag-chain tests, together with a maximum acceleration of 10 m/s² and a travel velocity up to 5 m/s. These limits support high-speed pick-and-place axes and long-stroke gantries. The cable diameter of 25.5 mm fits common energy-chain separators, and the PUR sheath maintains flexibility down to tight bend radii. During continuous stationary operation the conductor can reach 90 °C, while in moving chains it is rated for 80 °C, preventing insulation ageing under thermal load. The jacket’s low-friction surface keeps the cable from bonding to adjacent members and allows repeatable guided motion.
