Product Description:
The RKL4515 is a motor power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. Designed for dynamic routing between drive controllers and servomotors, the cable carries both mains power and auxiliary control cores, ensuring regulated energy delivery and signal continuity in moving-axis assemblies on modern production machinery.
The power cores are rated for 600 V AC, allowing direct connection to standard Rexroth servo inverters without additional step-down devices. Each phase conductor has a cross-section of 16.0 mm², balancing ampacity with manageable cable bulk, while the overall diameter of 25.5 mm fits common cable-chain separators. Copper resistance of 1.21 Ω/km limits voltage drop on long runs, and a capacitance of 1.2 nF/m controls reactive current in high-frequency switching environments. The PUR outer jacket shields the cores from cutting oils and welding spatter, supporting reliable service in harsh factory cells.
Mechanical properties match the electrical performance. The cable withstands carrier speeds up to 5 m/s and horizontal strokes reaching 50 m without exceeding tensile or flexural limits. During repetitive bending the minimum dynamic radius is 7.5 x D; when clamped permanently the requirement relaxes to 5 × D, preserving copper stranding integrity. Continuous operation is permitted up to +90 °C in fixed routing and up to 80 °C in constantly flexing sections, so enclosure temperatures seldom force derating. A dedicated 1.5 mm² control pair inside the sheath transmits brake or thermistor signals, simplifying harness architecture.
Wake Industrial offers a 1-year warranty on every RKL4515 cable, supports international shipping options for global plants, and maintains a free chat tool for general questions on type codes or specification details.
