Product Description:
The RLB3-044ECB is a flexible power lead produced by Bosch Rexroth Indramat for the RLB Motor Power Cables series. It is intended to run directly between an MS2 synchronous motor and an EFC inverter, delivering phase power while maintaining signal integrity in dynamic cable tracks common to packaging machines and small-gantry robots. By pairing a standardized conductor set with the manufacturer’s approved plugs, the cable forms a matched component within Rexroth installation guidelines for automated axes.
A service life of 5,000,000 cycles indicates the jacket and conductors can tolerate frequent flexing before fatigue becomes critical. During motion the cable may bend around energy-chain pulleys as tight as 7.5xD; when installed permanently it may rest in loops as small as 5xD. Current is carried through copper cores sized at 2.5 mm², supporting typical continuous-duty motor currents without excessive voltage drop or heat rise. The insulation and sheath materials remain stable up to 80 °C, so the assembly can pass near drive heatsinks or inside warm machine bases without derating. These geometric and thermal ratings define the basic design envelope and ensure predictable behavior under repetitive acceleration profiles.
The cable terminates on the motor side with a plug coded V, locking to the MS2 housing without adapters, and its construction supports a direct motor-drive connection that omits junction boxes for reduced EMI risk. When coupled to controllers in the EFC family it satisfies shielding and earth-bonding rules for pulse-width modulated outputs, while compatibility with the MS2(X) motor series aligns conductor arrangement to stator current requirements. Minimum service temperature of -30 °C allows machine operation in cold-storage or unheated plants as long as dynamic motion is not impeded by ice formation.
Wake Industrial stocks this cable, offers same-day shipping options for urgent orders, and backs every purchase with a 1-year warranty.
