Product Description:
The RKL4718 cable is produced by Bosch Rexroth Indramat and belongs to the RKL Motor Power Cables series. It functions as the primary power link between IndraDrive converters and synchronous motors, carrying three-phase energy and auxiliary signals while tolerating continuous flexing inside cable chains. In automated machining and handling cells, this dedicated motor cable streamlines installation because both the drive-side connector and motor-side terminations are predefined by the manufacturer.
The cable houses 3 power conductors each with a cross-section of 2.5 mm², providing the current-carrying capacity required by mid-range servo axes. A high-cycle design verified for 5,000,000 bending cycles supports rapid-fire motion sequences without conductor fatigue. During dynamic movement, curvature is limited to a minimum of 7.5×D, so energy chains can be specified confidently. On the drive end a keyed RLS0723 (K03) connector is moulded to the sheath, enabling direct plug-in to Rexroth power modules and eliminating field crimping.
When machines are parked or routed statically, the cable can be formed down to 5×D without violating sheath integrity. Internal control wiring is supported by 4 auxiliary conductors, allowing temperature sensors or brakes to share the same run; each auxiliary core is sized at 1.0 mm² to match low-level signal demands. At the motor end, conductors terminate inside the sealed RLK1301 terminal box, reducing on-site wiring time and preserving IP protection. The compound jacket continues to flex reliably from –30 °C up to 80 °C, covering cold-start warehouses and heated production floors alike.
Wake Industrial stocks this cable assembly, and same-day shipping is available for urgent orders. Quotations issued for the RKL4718 remain valid for 30 days. Customers benefit from knowing that the product is in stock when immediate replacement is required.
