Product Description:
The RLB2-042DBB cable is produced by Bosch Rexroth Indramat and assigned to the RLB Motor Power Cables series. It functions as a dedicated power link between MS2(X) servo motors and ctrlX DRIVE inverter systems, transferring motor phase energy while complying with installation requirements inside industrial automation cabinets and on moving machine axes.
This model uses a Basic cable design with a cabling structure of 4x L + 4x 0.75 mm², so four power conductors are paired with four smaller signal cores for brake or sensor functions. Each power core has a cross-section of 1.5 mm², allowing the assembly to carry an effective current up to 15.6 A without overheating when routed in energy chains. A measured leakage capacitance of 0.4 nF/m helps keep common-mode interference low, which is important for drive controllers that use high-frequency pulse-width modulation. When the cable is in continuous motion, its PUR sheath tolerates a minimum flexible bending radius of 7.5 × D, limiting mechanical stress on the copper conductors during repeated cycles.
For permanently routed sections, the bending limit relaxes to 5 × D, reducing space requirements inside stationary cable ducts. The external color is Orange (RAL 2003), making the assembly easily distinguishable from signal wiring, and the outer sheath is formed from PUR (orange RAL 2003) to provide abrasion resistance and coolant tolerance. Power conductors correspond to AWG 16, enabling straightforward termination with standard industrial crimp contacts. As part of the Rexroth Cables product group, the unit meets the electrical and mechanical parameters demanded by ctrlX DRIVE controllers while matching the connection geometry specified for the MS2(X) motor series.
