Product Description:
The RKL4334 cable is produced by Bosch Rexroth Indramat and belongs to the RKL Motor Power Cables series. It is a motor-side power supply lead that links an Indramat drive controller to a servo or spindle motor in automated machinery, transferring three-phase power and auxiliary control signals while withstanding continuous motion inside cable tracks.
The three copper power conductors have a cross-section of 35.0 mm², enabling low-loss delivery of motor current up to the cable’s rated 600 V AC. Their DC resistance is limited to 0.554 Ω/km, which keeps voltage drop small over long runs. At the controller end, an angled hybrid plug identified as RLS0724/K35 terminates both power and control cores; the overall sheath diameter is 30.8 mm, so standard EMC glands sized for that width can be used. Inside the bundle, a separate pair with a 1.5 mm² cross-section carries brake or temperature signals, and the cable’s mutual capacitance is specified at 1.2 nF/m, a value that guides drive-side output-filter selection when long lengths are installed.
Mechanical service life is defined for up to 5,000,000 flex cycles in drag-chain applications, provided that the dynamic bend is limited to 7.5xD and static routing observes the 5xD radius. A matte, adhesion-free jacket made of PUR (adhesion-free, matte) resists cutting oils and allows tight bundle packing, while the high-visibility sheath colour is coded as RAL 2003 (orange) for quick identification in crowded control cabinets. The motor is connected through the shielded RLS1301/C35 plug, and the cable includes drain wires that maintain full EMC shielding performance even when subjected to torsion. Together, these features let the RKL4334 handle rapid axis motion, resist industrial fluids, and maintain signal integrity without compromising electrical ratings.
