Product Description:

The RKL4488 cable is a motor power cable manufactured by Bosch Rexroth Indramat within the RKL Motor Power Cables series. Designed for linking servo drives to synchronous motors in dynamic machinery, it carries three-phase power, protective earth, and dedicated control cores to support safe operation and feedback in automated production cells.

The cable’s mechanical endurance is rated for 5,000,000 bending cycles, so it withstands continuous drag-chain movement without early conductor fatigue. Inside the sheath, there are 4 dedicated control wires that relay brake or sensor signals independently from the power cores. Each power conductor has a cross-section of 10.0 mm², enabling high current delivery to medium-frame motors with limited voltage drop. When installed permanently, the conductors tolerate temperatures up to +90 °C, allowing proximity to warm drive cabinets. For static routing the minimum bend radius is 5xD, permitting compact loops in control panels without stressing the insulation.

During gantry motion the cable flexes; for dynamic chains the conductor temperature limit is +80 °C and the minimum bend radius tightens to 7.5xD. A robust PUR outer jacket coloured orange (RAL 2003) shields the cores from oils and welding sparks while maintaining low friction in energy tracks. Termination at the motor side is sealed through a M32 x 1.5 thread gland, and the opposite end mates with an RLS0723 (K10) controller connector to streamline cabinet wiring.

Wake Industrial offers same-day shipping options for urgent maintenance schedules. Quotations on the RKL4488 remain valid for 30 days, giving buyers time to coordinate purchase orders.
