Product Description:
The RKL4608 is a motor power cable produced by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It serves as the fixed link between a Rexroth controller and an industrial servo or spindle, supplying mains power, auxiliary voltage, and control signals in one routed bundle. Factory-installed contacts on the cable’s drive end match the RLS0721/K10 plug, allowing direct connection to cabinet terminals without field crimping. This construction streamlines installation in automated handling equipment and helps maintain uniform impedance along the power path.
The copper power cores measure 10.0 mm², while auxiliary conductors are rated at 1.5 mm² and the separate control pair is 1.0 mm²; these cross-sections define the current-carrying capacity and allowable voltage drop for each circuit group. Cable family code INK0605 identifies the shielding, filler, and braid format used throughout the RKL line. An overall diameter of 22.2 mm balances conductor size with manageable weight for routing through energy chains. The assembly is declared halogen-free to limit corrosive gas release during an over-temperature event, and it is approved for continuous operation inside drag chains where repeated acceleration can fatigue lesser jackets. The controller end is finished with the RLS0721/K10 circular connector, providing secure locking, strain relief, and EMC continuity between the cabinet and moving axis.
Mechanical flexibility is supported by a dynamic bend radius of 7.5xD and a fixed bend radius of 5xD, enabling tight loop routing without harming conductor insulation. The outer sheath is colored Orange (RAL 2003) for easy visual identification along the machine frame, and its PUR material resists cutting oils, weld spatter, and abrasion during reciprocating travel. Because the jacket does not contain halogens, surface combustion residues remain non-corrosive, complementing the cable’s suitability for confined electrical cabinets and robotic drag chains.
