Product Description:
The RKL4330 cable assembly is produced by Bosch Rexroth Indramat and belongs to the RKL Motor Power Cables series. It serves as the power link between an IndraDrive controller and a servo motor, carrying the three-phase supply as well as auxiliary lines that support feedback, brake release, or sensor functions within automated machinery.
Each of the four main conductors measures 16.0 mm², giving the cable the current-carrying capacity needed for medium-power drives. The core is manufactured from the bulk cable type INK0606, whose finely stranded copper and PVC insulation balance flexibility with abrasion resistance. During continuous motion applications the jacket can follow a dynamic bend of 7.5xD and still complete about 5000000 bending cycles before fatigue becomes critical. At the control-cabinet side the assembly terminates in an angled hybrid connector coded RLS0723/K16, matching the power module’s high-density outlet and removing the need for field wiring.
Four auxiliary conductors, each rated at 1.5 mm², run in parallel with the mains to supply low-level signals or brake power without separate cabling. When the installation is fixed, the cable can sit in a static loop of 5xD without exceeding strain limits, and the motor end is equipped with a robust bayonet connector identified as RLS1301/C16 for secure latching under vibration. The operating envelope extends from −30 °C up to 80 °C, so the same assembly can be routed through cold storage zones and warm drive cabinets without material change. Storage limits mirror this range, and the listing as a power cable confirms that its insulation and conductor layout are optimized for motor‐phase voltages rather than signal fidelity.
