Product Description:
The RKL4332 cable is a motor power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It links servo drives to synchronous or induction motors, carrying three-phase power and protective earth along fast-moving axes in industrial automation equipment. By pairing with Rexroth drive systems, the assembly handles dynamic motion profiles on linear gantries, pick-and-place modules, and other machinery where continuous flexing and low electrical resistance are required for reliable torque transmission and coordinated multi-axis control.
The cable’s mechanical life is rated for 5,000,000 bending cycles, meaning it can flex this number of times in an energy chain before conductor fatigue becomes critical. During motion, a dynamic minimum loop of 7.5xD prevents core deformation, while stationary routing permits a tighter 5xD radius for cabinet wiring. A maximum permissible acceleration of 10 m/s² defines how quickly a carriage can ramp speed without overstressing the copper strands or outer jacket. System designers can run the cable on tracks up to 50 m in horizontal travel, supporting long strokes on transfer lines and gantry systems where sliding or rolling carriers guide the bundle.
For power transmission the four main conductors use a cross-section of 35.0 mm², delivering low impedance paths for phases L1, L2, L3 and the protective ground. The integrated pair of control cores is sized at 1.5 mm², enabling brake or sensor feeds without an external harness. Motor-side termination is achieved with the keyed circular connector RLS1301/C35, while the drive end mates to the compact RLS0723/K35. The assembly is built from bulk cable type INK0667, is not suited for simultaneous bending and torsion, and carries four color-coded power conductors for straightforward installation.
