Product Description:

The RLB3-044GDB belongs to the RLB Motor Power Cables series manufactured by Bosch Rexroth Indramat. As a dedicated power link between MS2(X) servomotors and EFC drive controllers, the cable routes three-phase supply and auxiliary conductors while withstanding continuous motion in energy-chain installations. Its basic construction and PUR outer jacket make it suitable for industrial automation cells where oil, abrasion, and vibration are present.

The four power cores have a conductor cross-section of 6 mm², allowing the assembly to carry up to 38.2 Aeff without exceeding permissible temperature rise. An overall diameter of 18.2 mm balances thermal dissipation with flexibility, and the PUR sheath adds cut resistance as well as coolant immunity. An integrated screen supports EMC compliance, terminating cleanly in the factory-molded M40 Power Connector for rapid motor exchange. Internal cabling follows a 4×L + 4×1.0 mm² + 2×1.5 mm² layout, so feedback voltage and brake lines can be carried alongside the main phases without separate conduits.

Dynamic durability is emphasised by a test rating of 5,000,000 bending cycles when the installation observes a minimum loop of 7.5xD. In static trays or vertical runs the radius may be reduced to 5xD with no compromise to insulation life. Capacitance between cores and shield remains low at 0.5 nF/m, reducing reactive current and easing the burden on drive output filters during long-distance runs. These parameters ensure predictable torque response, electromagnetic compatibility, and long service intervals in gantries, pick-and-place arms, or palletizing axes.

Wake Industrial offers international shipping options, can arrange same-day shipping for urgent orders, and keeps quotations valid for 30 days to streamline procurement scheduling.
