Product Description:
The RLB2-041FDB cable is manufactured by Bosch Rexroth Indramat and belongs to the RLB Motor Power Cables series within the Rexroth Cables product group. This basic-design power lead carries three-phase output from a drive to a synchronous motor through a direct connection layout. When installed in moving axes, it maintains electrical continuity between inverter hardware and the motor while tolerating repeated flexing.
A conductor cross-section of 4 mm² defines the allowable current density and voltage drop over the routed distance, making the assembly suitable for medium-power stages in machines. The jacket compound is qualified for 5,000,000 bending cycles, so the lead can move continuously in drag-chain applications without fatigue failure. During motion, the manufacturer prescribes a dynamic bending radius of 7.5xD, where D is the outer diameter, to prevent conductor strand damage. Thermal limits are defined by a maximum operating temperature of +80 °C and a minimum of -30 °C; within this span the insulation retains dielectric strength under load. The cable type is identified as a power cable, and its direct termination style eliminates extra plugs or field-installable housings, reducing contact resistance.
When installed in static segments of the routing path, the permissible bend tightens to the 5xD static radius, accommodating compact cabinet layouts without overstressing the copper cores. An integrated M40 motor connector on the load side mates directly with MS2(X) stator sockets, ensuring strain-relieved engagement and reliable shielding continuity. The cable is explicitly released for the ctrlX DRIVE platform, which simplifies parts selection because both ends share Rexroth locking standards. Compatibility with the MS2(X) motor series confirms phase assignment and insulation coordination, allowing the same lead to serve multiple frame sizes across that range. Identical storage and transport temperature limits of +80 °C and –30 °C mean spooled assemblies can sit in unconditioned warehouses without service life penalties.
