Product Description:
The RLB2-063KEB cable belongs to the RLB Motor Power Cables series produced by Bosch Rexroth Indramat. It is supplied as a flexible power link between MS2(X) servo motors and their associated drive modules, enabling reliable three-phase power delivery while withstanding repetitive motion in gantries, pick-and-place axes, and other automated assemblies. Its pre-terminated interface simplifies installation and maintains consistent electrical performance in demanding industrial automation layouts. The flexible construction also allows the cable to follow moving equipment without placing excessive mechanical stress on its conductors or outer jacket.
The conductor bundle has a cross-sectional area of 25 mm², giving the assembly the current-carrying capacity required for medium-frame servo motors that draw high peak currents during acceleration. On the motor side, a keyed M58 connector locks securely to the housing, while the other end is prepared for a direct connection to the drive. This arrangement avoids intermediate terminal blocks in the power path and supports an orderly connection between the motor and drive. The jacket withstands repetitive flexing at a minimum dynamic bend radius of 7.5 × D. Its internal braid and insulation stack are rated for at least 5,000,000 bending cycles in continuously moving drag-chain applications. The compact bend radius allows the cable to operate in confined carrier systems while limiting stress on the internal conductors and insulation layers.
During stationary routing, the cable can be formed to a minimum static bend radius of 5 × D, allowing compact cabinet layouts without violating the insulation system’s bending limits. The permitted temperature range extends from -30 °C to +80 °C, allowing the assembly to be routed through cold areas or near drive heat sinks without losing flexibility or dielectric strength. The cable uses A/B connector coding to match the required plug orientation and prevent accidental cross-mating with incompatible cable families. Correct observation of the dynamic and static bend radii helps prevent jacket deformation where the cable enters a carrier, cabinet, or machine housing. The broad operating temperature range also supports installations exposed to substantial temperature changes during normal machine operation.
