Product Description:
The RKL4504 is a motor power cable manufactured by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It serves as the fixed or dynamic link between a drive controller and a synchronous or asynchronous motor, carrying three-phase power, control, and auxiliary signals in industrial automation equipment. By combining multiple conductor groups under a rugged polyurethane jacket, the cable simplifies installation in control cabinets and on moving axes while maintaining electrical integrity during continuous bending or stationary routing.
Its power core consists of 4 x 10.0 mm² copper conductors that accommodate drive currents for motors up to the medium-power range. Both the power and embedded control circuits are rated for 600 VAC, permitting common supply and feedback voltages without separate cable types. A robust overall diameter of 22.2 mm limits voltage drop over long runs while withstanding mechanical stress in cable chains. Typical line-to-shield capacitance is 1.0 nF/m, a value that influences inverter-side filter design for high switching frequencies. Direct-current loop resistance is specified at 1.91 Ω/km at 20 °C, allowing designers to calculate thermal rise and verify drive protection parameters.
The signal bundle carries two twisted pairs: a control pair sized at 2 x 1.0 mm² for encoder-enable lines and an auxiliary pair of 2 x 1.5 mm² reserved for brake release or temperature sensors. A halogen-free PUR sheath resists oil, coolant, and abrasion, and it is approved for high-cycle drag-chain operation, matching the dynamic axis requirements of pick-and-place gantries. Jacket tint follows RAL 2003 orange for quick identification among other cable groups. When fixed, the conductors tolerate temperatures up to 90 °C, while repetitive motion applications are limited to the flexible rating of 80 °C, ensuring insulation stability throughout the service life.
