RKL4630 by Bosch Rexroth Indramat

The RKL4630 is a factory-terminated motor power lead produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. Designed for servo drive packages, the assembly carries three-phase power from the inverter to the motor while maintaining consistent conductor spacing and shielding. In automated machinery, the cable provides a ready-to-install link that reduces wiring time and ensures that the electrical path follows the manufacturer's recommended impedance.

Mechanical flex performance is rated for 5,000,000 bending cycles, indicating how many repeated motion events the jacket and conductors can withstand before fatigue becomes critical. Cable routing is limited to a 7.5 × D dynamic bending radius during motion and a 5 × D static bending radius when the installation is stationary; in this case, D refers to the outer diameter, so these ratios set minimum loop sizes that help prevent core damage. Both ends arrive with ferrules and ring terminal connectors, eliminating the need for crimping and enabling direct attachment to terminal studs or clamp blocks. Because the product is supplied as a ready-made assembly, length selection and high-frequency shielding are handled at the factory, which helps avoid on-site preparation errors.

This cable is classified as a power cable, so it is intended for energy transmission rather than feedback or sensor tasks. Continuous service is allowed between a -30 °C minimum operating temperature and an 80 °C maximum operating temperature; within this range, insulation elasticity and dielectric strength remain stable under load. When the machine is idle, storage areas must maintain a -30 °C minimum storage temperature to help prevent micro-cracking of the outer sheath during later startup. These temperature limits allow installation in unconditioned panels or moving cable tracks that experience seasonal variation without reducing conductor integrity or insulation resistance.
