Product Description:
The RL2-542FBB motor power cable is produced by Bosch Rexroth Indramat within the RL2 Motor Power Cables series. As part of the Rexroth Cable product group, it links drive controllers to second-generation motors, carrying three-phase power while withstanding dynamic routing inside moving cable carriers common in automated machinery. Its construction targets mechanical endurance, chemical resistance, and dimensional stability so that power delivery remains consistent throughout extended duty cycles.
Built with a Basic cable design, the model is rated for 5 million bending cycles in energy-chain applications. Movement is further supported by a minimum dynamic bend radius of 7.5xD, preventing copper work-hardening during rapid accelerations. Each power core offers a cross-sectional area of 4.0 mm², and the entire bundle is sized at 17.0 ±0.5 mm in outside diameter, simplifying conduit selection and fill calculations. A jacket of PUR (RAL 2003) shields the conductors from coolants, oils, and welding spatter while retaining flexibility at low temperatures. These characteristics, combined with the 2nd motor generation pin assignment, allow the cable to deliver continuous current without excessive resistive heating or mechanical wear.
For fixed routing the cable permits a static bend radius of 5xD, making cabinet layouts compact. Its internal geometry follows the arrangement 4x L + 4x 0.75 mm², separating auxiliary control lines from the power cores to suppress crosstalk; remaining capacitive coupling is limited to 0.5 nF/m, which keeps drive-side displacement current low over long runs. A factory-molded size M40 connector mates directly with motor terminals, eliminating field crimping and ensuring correct shield termination. Together these features complement the dynamic ratings discussed above by streamlining installation and maintaining electromagnetic compliance in stationary sections of the wiring path.
