Product Description:
The RKL4414 cable is a motor power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It is intended to carry drive voltage and auxiliary signals between servo drives and motors in automated machinery, supporting coordinated motion and feedback circuits across moving axes. Because the cable is rated for dynamic applications, it maintains electrical integrity during constant flexing in robotic, gantry, and packaging lines.
Electrical parameters begin with a capacitance of 1.0 nF/m, a value that defines the charging current drawn by drive inverters over every meter of installed length. Conductor resistance measured at 20 °C is 1.91 Ohm/km, limiting I²R power losses and voltage drop on long cable runs. Four power cores sized at 4x10.0 mm² deliver sufficient cross-section for typical medium-frame servo motors, while two differential signal pairs sized (2x1.0 mm²) + (2x1.5 mm²) accommodate temperature sensors and brake control. A composite outside diameter of 22.2 mm results from this conductor set and its layered insulation, letting installers specify matching glands and drag-chain separators.
Mechanical design focuses on continuous movement. The sheath is colored RAL 2003 (Orange) for quick identification in control cabinets, and the abrasion-resistant PUR jacket stands up to oil and coolant exposure. For stationary routing the cable may be bent to a minimum radius of 5 × D; during dynamic cycles the limit is 7.5 × D, so it can flex thousands of times in drag-chain carriers without cracking. A specific mass of 0.870 kg/m allows easy calculation of chain loading, and the manufacturer certifies the cable for drag-chain use so no additional support saddles are required.
