Product Description:
The RKL0055 belongs to the RKL Motor Power Cables series produced by Bosch Rexroth Indramat. It is a dedicated motor power cable that links IndraDrive or other Rexroth drive controllers to matching servo motors, carrying phase current as well as low-level control and protective signals required in automated machinery. By integrating matched connectors at both ends and using a polyurethane outer jacket, the cable provides a packaged solution that simplifies wiring runs inside robots, gantries, and other motion systems where electrical noise immunity and mechanical durability are critical.
The overall outside diameter is 18.5 mm, giving installers a clear reference for cable tray spacing and gland selection. Power conductors inside the bundle use a cross-section of 6.0 mm², allowing continuous transmission of motor current without excessive voltage drop. Copper resistance measured at 20 °C is 3.30 Ω/km, which helps determine allowable run length before efficiency or servo performance is affected. Drive-side termination is handled by the keyed circular connector RLS0749/K06, ensuring shield continuity at the cabinet interface. Between conductors and shield, the capacitance is held to 0.8 nF/m, limiting reactive loading on the inverter and reducing common-mode interference with encoder feedback lines routed nearby.
For dynamic cable chains or robotic joints, the flexible installation radius is limited to 7.5 × D, minimizing conductor fatigue while still supporting tight routing paths. At the motor end, plug-and-play engagement is achieved with the molded connector RLS1301/C06, which carries both power phases and two pairs of screened control cores. The outer sheath is colored RAL 2003 (orange) for clear identification of live motor wiring, and it is extruded from PUR (adhesion-free, matt) to resist oil, coolant, and abrasion. Control cores of 1.0 mm² and 1.5 mm² support temperature sensors or brakes, completing the multifunction cable design.
