Product Description:

The RKL4704 cable is produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. As a pre-assembled power lead it links drive controllers to servo motors, carrying phase, earth and auxiliary cores in a factory-terminated sheath for predictable impedance and noise control. It supports decentralised drives where installation speed and routing flexibility are essential on moving gantries, pick-and-place units, and robotic wrists.

Three phase cores each with a cross-section of 2.5 mm² form the main current path, while 3 power conductors are supplemented by four auxiliary pairs sized at 1.0 mm² to feed brakes, sensors or temperature probes. The presence of 4 auxiliary conductors allows separate low-power circuits without adding extra harnesses. Installation in fixed trays is simplified by a static bending radius of 5xD, preventing jacket kinks when corners are tight and minimising mechanical stress on the copper strands.

The Basic cable model is rated for 5 million flex cycles and tolerates a dynamic bend as tight as 7.5xD, so it can run inside energy chains on continuously moving axes. Service temperature spans from -30 °C during cold starts up to 80 °C in operating zones, eliminating seasonal change-overs and ensuring constant dielectric properties. A single PE protective conductor is integrated for safety, and identical storage limits mean spare assemblies preserve performance when held in inventory.

Wake Industrial offers same-day shipping options when replacement cabling is required quickly. Quotations issued for RKL-series leads remain valid for 30 days, giving planners time to align budgets. For specification details or fault-code discussions, customers can use the free chat tool.
