Product Description:

The RKL4701 cable is manufactured by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It serves as the dedicated power and control link between IndraDrive controllers and servo motors, routing three-phase supply conductors and feedback pairs through a single sheath for compact machine wiring in dynamic industrial automation systems.

During continuous motion the cable can flex safely at a minimum radius of 7.5 x D, making it suitable for cable carriers on moving axes. It is supplied as bulk type INK0653 and built with a 4×1.0 mm² power core plus two shielded twisted-pair control circuits, each 0.75 mm², to carry encoder or brake signals. The total outside diameter measures 12.0 mm (±0.5 mm), allowing routing through standard energy-chain separators, while the bright RAL 2003 (orange) jacket provides quick identification inside the cabinet.

Electrical characteristics are sized for medium-power axes. Line conductors are rated 1.0 mm² and can carry up to 300/500 V, while the control pairs operate at 300/300 V. A low discharge capacity of 0.6 nF/m helps preserve signal integrity over long runs, and conductor resistance is held to 19.5 ohm/km at 20 °C to limit voltage drop. The matte outer sheath is formed from PUR (adhesion-free, matte), resisting oils and remaining flexible after lengthy drag-chain cycles. For quick installation the reel is delivered with connector RLS0722/K01 for the controller and RLK1201 for the motor.

Wake Industrial stocks this cable and can arrange same-day shipping for time-critical orders. A 1-year warranty is provided on every purchase. Customers may use the free chat tool to ask about type codes or wiring details before ordering.
