Product Description:

The RKL4760 cable is part of the RKL Motor Power Cables series from Bosch Rexroth Indramat. It serves as a factory-terminated link between IndraDrive controllers and servo motors, carrying three-phase power, protective earth, and auxiliary control pairs inside a PUR jacket so that machine builders can install a single assembly instead of separate loose conductors.

This model is fabricated from bulk cable type INK0603, which yields a conductor resistance of 4.95 Ohm/km for predictable voltage drop calculations over long runs. Power and control cores are rated to 600 V AC, matching drive output stages. The 5–6 control pair employs a cross-section of 1.0 mm² to handle encoder supply currents, while the controller end is finished with a RLS1202/C04 quick-lock connector that seals against dust when mated. A matte, adhesion-free PUR sheath resists oils and abrasion, and the cable’s specific capacitance of 0.8 nF/m minimises reactive loading on pulse-width-modulated drives.

The motor interface uses a rugged RLK1301 connector, and the 7–8 auxiliary pair is upsized to 1.5 mm² for brake circuits that demand higher current. Three power conductors plus PE are stranded at a cross-section of 4.0 mm², providing ample ampacity while keeping overall diameter moderate. Installation inside energy chains is supported by a fixed bend radius of 5 x D and a flexible radius of 7.5 x D; temperature limits reach +90 °C for static routing and +80 °C during dynamic motion.

Wake Industrial stocks this cable, offers same-day shipping options, and keeps quotations valid for 30 days to streamline maintenance planning.
