Product Description:
The RKL0042 motor power cable is produced by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It routes drive output and auxiliary signals between Rexroth servo drives and moving motors, supporting cable-chain or robotic layouts found in industrial automation. A concentric arrangement of power cores and auxiliary conductors is enclosed in a single sheath, allowing panels to be wired efficiently while limiting electromagnetic coupling with adjacent control circuits.
The power phase conductors each have a cross-sectional area of 10.0 mm², giving the cable the current-carrying capacity required for medium-frame synchronous motors. The DC resistance of these conductors is limited to 1.91 Ω/km at 20 °C, keeping voltage drop low across long machine axes. An additional trio of auxiliary conductors is provided, each with a cross-sectional area of 1.0 mm², to carry brake or sensor voltage without a separate harness. The cable has an overall diameter of 22.2 mm, allowing it to fit common 25 mm energy-chain cavities. Its outer jacket is molded from PUR for abrasion resistance, oil tolerance, and continuous-flex operation. The jacket is orange with an RAL 2003 color designation, making the cable easy to distinguish within an energy chain.
The cable withstands 5,000,000 flexing cycles without conductor breakage when it is installed according to the applicable bend-radius limits. A fixed installation requires a minimum bend radius of 5 × D, while the bend radius under moving conditions must not fall below 7.5 × D to preserve the conductor stranding. Fixed installations support an operating temperature range of -30 to +40 °C. During motion, the cable can operate at temperatures as low as -20 °C because the PUR jacket remains flexible. These operating characteristics support cable-chain routing in packaging lines, material-handling gantries, robotic systems, and other positioning equipment that undergoes frequent movement. The jacket also protects the enclosed conductors from the abrasion and oil exposure commonly encountered around automated machinery.
