Product Description:
The RKL0045 cable is produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It serves as the primary power link between an IndraDrive controller and a synchronous motor in automated axes, carrying three-phase supply and auxiliary sensor lines while tolerating continuous motion inside drag-chain assemblies. The design addresses high-cycle flexing environments often found in pick-and-place gantries, packaging units, and multi-axis machining centres.
Inside the INK0650 bulk cable core, three power conductors rated at 3 x 1.5 mm² are laid with four auxiliary cores of 4 x 0.75 mm²; this 4x1.5 + 4x0.75 mm² (StC) arrangement keeps voltage drop and control-voltage separation within accepted limits for servo feeds. The construction is sheathed in a PUR jacket that resists oils, coolants, and weld spatter, yet keeps the overall diameter to 12.2 mm so it fits standard energy-chain clamps. During reciprocating motion the cable may flex to a dynamic bend radius of 7.5 x D without exceeding conductor strain. The motor side is terminated with an RLS1301/C03 angled connector, while the controller end uses the RLS0746/K02 straight plug, allowing fast exchange without tool-based re-wiring.
Mechanical longevity is defined by a static bend radius of 5 x D for fixed routing and a tested endurance of 5 million cycles under drag-chain operation. Electrical parameters include a line-to-line capacitance of 0.8 nF/m, which limits displacement current at high PWM frequencies, and a conductor resistance of 13.3 Ω/km, which helps control I²R heating on extended runs. Together with the cable construction and connector pairing, these values support reliable torque delivery, minimal electrical noise, and predictable service intervals in high-dynamic automation tasks.
