Product Description:

The RKL4483 is a motor power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It links IndraDrive controllers to the motor terminal box, carrying three-phase supply and auxiliary signals while tolerating continuous flexing in cable chains. By combining screened power cores with dedicated control pairs, the assembly preserves signal integrity and simplifies installation inside dynamic automation cells.

This model contains 4 power conductors, each sized at 6.0 mm², so it can transmit substantial current to medium-frame servomotors without overheating. A finely stranded construction allows a dynamic bend radius of only 7.5xD, reducing stress when the cable is routed through tight loop carriers. Endurance is certified for 5,000,000 bending cycles, making it suitable for high-duty linear axes and robotic wrists. The core bundle is extruded in the resistant INK0604 bulk jacket compound, which shields against coolants and lubricants commonly encountered on metal-cutting machines. At the control end, an RLS0721/K06 plug mates directly with the drive’s power module, eliminating field crimping and ensuring consistent contact resistance.

Installation flexibility is increased by a static bend radius of 5xD when the cable is clamped in fixed trays. Thermal performance spans −30 °C to +80 °C, while cold-room operation is supported down to -30 °C without embrittlement. Ring terminals at the motor side (kit RLK0003) provide secure stud connections inside the terminal box and maintain low impedance even under vibration. Separate control pairs, sized 1.0 mm² and 1.5 mm², relay brake and temperature signals so additional harnesses are unnecessary.

Wake Industrial stocks this cable and can arrange same-day shipping. Every unit is supplied with a 1-year warranty. Price quotations remain valid for 30 days.
