Product Description:
The RLB2-043GDB is a power cable manufactured by Bosch Rexroth Indramat and supplied within the RLB Motor Power Cables series. Classified under the Rexroth Cables product group, it links MS2(X) servo motors to ctrlX DRIVE controllers, transmitting main phase energy as well as brake and sensor supplies in dynamic gantry and handling equipment. The assembly integrates power conductors with auxiliary cores so that a single routed line provides both machine torque and essential feedback services.
For the primary phases the cable carries four 4x6.0 mm² copper conductors, giving an overall cross-section of 6.0 mm² and supporting a continuous load of 38.2 A at ambient conditions. Insulation ratings allow the power bundle to operate on 600/1000 V systems, while the control pairs are specified for 450/750 V. Additional 4 × 1.0 mm² and 2 × 1.5 mm² auxiliary wires are embedded in accordance with the ‘Basic’ cable design, matching the cabling code 4 × L + 4 × 1.0 mm² + 2 × 1.5 mm². A thermoplastic elastomer sheath tolerates a service window from -30 °C up to 80 °C, enabling installation in chilled warehouses and high-temperature enclosures. During continuous motion the construction accepts a minimum dynamic loop diameter of 7.5xD, preventing conductor fatigue in energy-chain applications.
Stationary runs may be laid to a bend radius of 5xD, and testing verifies endurance for 5,000,000 flex cycles, so the cable supports long-life duty in high stroke conveyors. The outer jacket is PUR (Orange RAL 2003), offering abrasion resistance and oil immunity while remaining highly visible in machine interiors. Motor terminations are accomplished through an M40 threaded connector; the opposite end can be freely prepared for drive cabinet glands. Storage limits mirror operational ones, with permissible ranges from -30 °C to 80 °C, and the assembly qualifies as a power cable type under EN definitions.
