Product Description:

The RKL4629 is a motor power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. The assembly serves as the energized conduit between IndraDrive inverters and their attached servo motors, carrying drive current while maintaining signal integrity across moving machine axes. By combining mechanical flexibility with electrical shielding, the cable supports continuous cable-track operation in packaging lines, gantry loaders, and other high-duty industrial automation systems.

Durability under dynamic motion is rated for 5 million bending cycles, allowing repeated acceleration in drag chains without conductor fatigue. The cable uses 4 copper power conductors, each with a cross-sectional area of 35.0 mm², to carry the three-phase supply and protective ground. This conductor arrangement simplifies termination to standard motor connectors. During installation in moving carriers, the flexible segment may curve down to 7.5 × D, preventing undue stress on the insulation. Electromagnetic emissions are minimized through overall shielding that wraps the entire core bundle, provides a low-impedance return path, and reduces noise coupling between the motor and drive.

A mechanical safety margin remains when the cable is fixed in place, where the allowable bend is 5 × D. The sheath is molded from PUR, a thermoplastic polyurethane selected for resistance to abrasion, cuts, and microbes. Conductors may operate continuously at up to +80 °C without degrading the insulation. The jacket is halogen-free, oil-resistant, and resistant to hydrolysis in humid washdown areas. Its orange RAL 2003 color improves visibility in cable trays, while its silicone-free composition helps prevent contamination in paint shops. Two balanced pairs of 1.5 mm² control wires run alongside the power conductors to supply a brake or temperature sensors while sharing the same overall shield.
