RKL0037/005.0 (RLK3101-INK0602-RLS0721)

The RKL0037/005.0 (RLK3101-INK0602-RLS0721) is a ready-made power cable produced by Bosch Rexroth Indramat and supplied within the Cables And Accessories series. This preassembled lead links a Rexroth servo drive to its matched motor, eliminating field termination and supporting quick installation in industrial automation cells that depend on precise power and signal routing. By combining power cores, control pairs and a composite shield in a single flex-rated jacket, the assembly delivers both mains energy and low-level control feedback through one routed line.

It is delivered at a fixed length of 5.0 m, an option chosen to span common cabinet-to-axis runs without excess slack. Inside the outer jacket, four control conductors with a cross-section of 1.0 mm² carry sequencing signals that must remain below the 100 V insulation class assigned to the control pair. To survive dynamic routing, the cable is rated for 5000000 bending cycles in a drag-chain track, and its construction is confirmed for continuous drag-chain use. The thermoplastic sheath is Halogen-Free, limiting corrosive gas release during an overload event. A total copper braid and foil shield surrounds all cores, and a molded plug coded RLS0721 mates directly with the designated drive port.

On the motor side, the keyed connector RLK3101 terminates the four power cores that each provide a cross-section of 2.5 mm² to reduce voltage drop over the installed run. These conductors support a line-to-line rating of 850 V, allowing the assembly to service IndraDrive inverters that switch high intermediate-circuit voltages. DC resistance is specified at 8 Ohm/km at 20 °C, a figure used when calculating permissible continuous current relative to thermal limits. That screen keeps high-frequency drive pulses away from the adjacent control pair, and the outer jacket preserves the cable geometry during continuous flexing.
