Product Description:
The RKL4786 is a motor power cable manufactured by Bosch Rexroth Indramat within the RKL Motor Power Cables series. Designed for servo-class installations, this cable routes three-phase power and auxiliary control cores between an IndraDrive controller and a matched motor, providing a mechanically robust link that tolerates repetitive motion in cable chains and articulated carriers commonly found on industrial robots and gantry axes.
The cable is qualified for up to 5,000,000 dynamic bending cycles and may be fixed in place with a minimum radius of 5×D, while moving applications must respect a radius of 7.5×D; these limits protect conductor strands from fatigue. Overall conductor resistance is rated at 0.78 Ω/km (20 °C), assuring low voltage drop across typical machine lengths. With an outer diameter of 29.8 mm, installers can size energy-chain inserts accurately and calculate fill factors. The controller end terminates in an RLS0727 (K25) connector and the motor end in an RLK1301 (K25), allowing rapid, keyed mating without field crimping.
A flame-retardant, halogen-free PUR jacket colored RAL 2003 safeguards the cable against oils, coolants, and welding spatter. Inside, four power cores of 4×25.0 mm² handle continuous motor currents, while two shielded signal pairs and four 1.5 mm² control wires transmit temperature and brake information, keeping feedback circuits immune to drive-side switching noise. The fixed and flexible radius ratings, combined with the jacket material’s high abrasion resistance, make the assembly suitable for long-travel handling systems that demand both electrical integrity and mechanical endurance.
Wake Industrial stocks this cable and can arrange same-day shipping for urgent builds. Every purchase carries a 1-year warranty. Quotations issued for the RKL4786 remain valid for 30 days.
