Product Description:
The RKL4720 is a factory-terminated power cable from the RKL Motor Power Cables series produced by Bosch Rexroth Indramat. It links IndraDrive controllers to motor terminals, carrying mains power and auxiliary supplies while maintaining signal integrity inside dynamic robotic chains and gantry axes.
The copper power cores in this assembly have a cross-section of 4.0 mm², providing low resistive loss for continuous motor current. Separate auxiliary pairs for encoder heaters or brakes are sized at 1.0 mm² on conductors 5-6 and 1.5 mm² on conductors 7-8, matching typical peripheral loads without oversizing the cable bundle. Flex cycles are supported down to an ambient of −30 °C, so energy-chain applications in refrigerated halls remain feasible. During constant motion the jacket may bend to a minimum radius of 7.5xD, a figure that defines cable tray design and protects the internal shield. The assembly ships as a ready-made product, eliminating field crimping, and is built on INK0603 bulk stock for consistent insulation and sheath characteristics.
Endurance is verified for 5,000,000 cycles, ensuring long service before scheduled replacement in high-duty machines. When stationary runs are required, the cable accepts a tighter bend of 5xD without damaging the dielectric. Interface hardware is pre-installed: the controller side terminates in connector RLS0722/K04, while the motor end is fitted with RLK1301, allowing plug-and-play maintenance. Classified as a power cable variant within the RKL family, this harness simplifies bills of material by combining main and auxiliary conductors in one sheath.
Wake Industrial stocks this cable, and same-day shipping options are available when orders are placed before cutoff. Quotations remain valid for 30 days to support budget approvals. International shipping options can be arranged for customers outside North America.
