Product Description:
The RKL4729 power lead is produced by Bosch Rexroth Indramat for the RKL Motor Power Cables series and routes three-phase drive current from controller to servomotor in automated machinery. It is specified as a pre-assembled cable set that simplifies field wiring by combining the correct conductor cross-sections, insulation system, and connector pair into one article number. Within a motion axis it transmits continuous motor current, protective earth, and feedback sensor pairs while resisting mechanical stress imposed by cable tracks and repetitive cycling.
For dynamic motion the cable can flex down to a minimum radius of 7.5 × D, whereas static routing in fixed trays may tighten to 5 × D; these limits protect the copper stranding from fatigue. The bulk material is identified as type INK0667, a designation that defines insulation thickness, shielding, and dielectric ratings for high-frequency PWM outputs. Overall geometry follows the bundle scheme [4×35.0 mm² + 2×(2×1.5 mm²)StC]C, delivering ample phase capacity for medium-power motors while including twisted signal pairs for temperature or brake wiring. Line resistance is held to 0.554 Ω/km, so voltage drop remains low over typical machine lengths, maintaining torque accuracy.
The controller end terminates with connector RLS0723/K35, and the motor end uses RLK1301, permitting tool-free attachment to Rexroth drives and MSK or MKE motors. A bright RAL 2003 (orange) PUR jacket improves visibility in cabinets and endures coolants, while the compound is certified halogen-free to minimize corrosive gases during a fire. Drag-chain suitability is confirmed, and the PUR outer sheath together with internal fillers controls torsion so the assembly meets continuous-flex life targets.
Wake Industrial stocks this cable assembly, can arrange same-day shipping for urgent orders, and supplies a 1-year warranty on every purchase; a free chat tool is available for general questions about type codes or connector pinouts.
