Product Description:
The RKL4609 motor power cable from Bosch Rexroth Indramat is supplied in the RKL Motor Power Cables series and is intended to transfer drive power between a Rexroth controller and a moving servo motor. Its construction supports continuous flexing in cable chains so that automated axes can operate without electrical interruption. By combining series-matched connectors with finely stranded conductors, the assembly delivers stable three-phase power and auxiliary cores to dynamic machinery used in industrial automation.
Mechanical durability starts with an endurance rating of 5,000,000 bending cycles, allowing long service life in high-duty energy chains. During motion the jacket may flex down to a dynamic radius of 7.5xD, while fixed routing can tighten to 5xD without stressing the cores. Three power conductors, each sized at 10.0 mm², carry the main motor current, and additional cores of 1.0 mm² and 1.5 mm² support temperature sensors or brakes. This geometry keeps voltage drop low and avoids thermal buildup even under continuous acceleration.
Electrical behaviour is defined by the bulk cable code INK0605, which specifies insulation material, shielding and outer sheath for EMC compliance. Conductor resistance is limited to 1.91 Ω/km, restricting I²R losses over extended lengths, and a low mutual capacitance of 1.0 nF/m minimises reactive current at high switching frequencies. On the cabinet side the moulded RLS0723/K10 connector mates directly with IndraDrive or EcoDrive power terminals; at the motor end colour-coded ferrules fit into the WEF interface specified for Rexroth motors, producing a vibration-proof termination that resists loosening during rapid indexing.
Wake Industrial stocks this cable, can arrange same-day shipping when schedules are tight, and provides a 1-year warranty with every purchase.
