Product Description:
The RKL4528 is a motor power cable produced by Bosch Rexroth Indramat in the RKL Motor Power Cables series. Intended for servo-grade installations, the cable links Indramat drives to matched motors, carrying three-phase power and auxiliary signals while tolerating continuous movement inside dynamic machine axes.
The main conductors are dimensioned at 10.0 mm², providing low impedance for motors that draw high surge currents. Two auxiliary cores for temperature sensors or brake power feature a reduced cross-section of 1.0 mm², and a second pair for encoder supply is sized at 1.5 mm² to balance voltage drop against flexibility. Mechanical endurance is demonstrated by 5,000,000 bending cycles in drag-chain conditions, allowing deployment on high-stroke gantries. Electrical losses remain minimal thanks to a conductor resistance of 1.91 Ohm/km, helping drives maintain regulated DC-link voltage during acceleration.
Signal integrity is aided by a capacitance of 1.0 nF/m, which keeps reactive current manageable when cable runs exceed several meters. The outer PUR jacket is colored RAL 2003 for quick identification in control cabinets and remains adhesion-free to adjacent hoses. Fixed routing requires only a bend radius of 5 x D, while dynamic loops observe 7.5 × D, ensuring copper strands stay within elastic limits. The 22.2 mm outer diameter accepts standard strain-relief glands, and approval for use in cable drag chains confirms suitability for pick-and-place modules or tool changers.
Wake Industrial offers same-day shipping on this cable, keeps quotations valid for 30 days, and supports a free chat tool for questions about type codes or fault diagnostics.
