RKL0084 by Bosch Rexroth Indramat

The RKL0084 cable is a motor power lead produced by Bosch Rexroth Indramat and belongs to the RKL Motor Power Cables series. It is intended to carry drive power and auxiliary control signals between Indramat servo drives and synchronous motors within automated machinery. By combining shielded power conductors with smaller control cores in a single flexible jacket, the product simplifies routing inside moving gantries, pick-and-place axes, and other equipment that relies on continual motion under drag-chain guidance.

The cable is rated for 5 million flex cycles, indicating that its copper stranding and insulation can tolerate repeated articulation in energy-chain applications without conductor fatigue. A control pair with a cross-section of 0.75 mm² is integrated for brake release, temperature sensor, or feedback tasks, and this smaller gauge helps limit bundle diameter while still supporting logic-level loads. During movement, the sheath may bend to a minimum dynamic radius of 7.5 × D, so a chain cavity only needs to be 90 mm wide when the 12 mm outer diameter is considered. The orange tint coded as RAL 2003 (orange) improves visibility in crowded cabinets, and the PUR jacket with an adhesion-free, matte finish resists oil and weld spatter while preventing sticking to adjacent cables.

For the current-carrying conductors, the insulation system is rated at 600 V AC, allowing the same cable to feed low-voltage inverter outputs and monitor circuits without exceeding dielectric limits. The three-phase power trio uses a cross-section of 1.0 mm², supporting the modest motor currents found on compact axes while keeping the overall bundle lightweight. Copper loop resistance is 19.5 ohms/km, a value that should be considered when calculating voltage drop over long gantry runs. When the machine is at rest, the assembly can be laid in troughs with a static minimum bend radius of 5 × D, helping preserve conductor geometry during fixed routing.
