Product Description:
The RKL4743 cable is a motor power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It links drive controller and motor in servo machinery and endures continuous motion in gantry axes or robotic wrists. The outer jacket is PUR, adhesion-free and matte, coloured RAL 2003 orange for quick visibility, and it resists oils and abrasion in automated production lines. This mechanical resilience makes it suitable for packaging lines, material-handling gantries, and other axes that experience frequent direction changes.
The cable carries motor current through a power conductor with a cross-section of 35.0 mm²; separate auxiliary cores of 1.5 mm² serve brake or sensor circuits. Copper conductors with a resistance of 0.554 Ω/km limit voltage drop over long runs. For energy-chain use the design is rated for 5,000,000 bending cycles and remains flexible down to a radius of 7.5 × D without insulation damage. During motion the permitted conductor temperature reaches 80 °C. Such electrical parameters match synchronous servo drives operating at high peak currents while maintaining acceptable thermal limits inside cable tracks. These attributes let machine builders route the assembly alongside pneumatic hoses and sensor bundles without concern for excessive heat buildup or voltage sag.
In fixed routing the conductor can run at up to 90 °C, supporting high continuous currents. The cable’s outside diameter of 30.8 mm fits standard clamps, and a static bend radius of 5 × D is sufficient for cabinet wiring. Core-to-core capacitance is 1.2 nF/m, a value considered when selecting output filters. These mechanical and electrical parameters help the RKL Motor Power Cables series maintain predictable impedance and low leakage in precision automation.
