Product Description:
The RKL4605 power cable is produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. Designed for moving machine members, it delivers three-phase motor power from in-cabinet drives to field-mounted servomotors while withstanding tight routing inside cable tracks common to packaging, printing, and assembly equipment. Its matte, adhesion-free PUR jacket helps prevent stick-slip in bundles and resists coolants and common oils, therefore maintaining electrical continuity during prolonged service life.
It survives up to 5,000,000 dynamic bending cycles, a rating that matches long-life energy chain duty. When laid immobile it may be bent to a minimum radius of 5 x D; during reciprocating motion the limit shifts to 7.5 x D, keeping conductor strain below fatigue thresholds. The outer sheath measures 17.0 mm in diameter, so chain separators and gland fittings can be sized correctly. Four 4.0 mm² copper cores form the power group, and the loop resistance of those conductors is 4.95 Ω/km at 20 °C, a value that supports low voltage drop over typical machine runs. These mechanical and electrical limits allow the assembly to tolerate repeated acceleration without service interruptions.
Electrical behavior is defined by the INK0603 bulk construction, which matches the impedance requirements of Rexroth drive amplifiers. The motor side comes with Ferrules, and the control-cabinet side terminates in an RLS0721 connector, reducing wiring time. A distributed capacitance of 0.8 nF/m limits reactive currents during high-frequency inverter switching, keeping temperature rise in check and supporting electromagnetic compatibility. These features make the cable suitable for servo axes that combine fast motion with tight enclosure spaces.
