Product Description:

The 8BCM0025.1034C-0 cable is produced by B & R Automation as part of the 8BC ACOPOS Cables series. It serves as a combined power and signal link between ACOPOS servo drives and moving loads in automated equipment. By carrying motor power, brake wiring, and feedback conductors inside one flexible assembly, it keeps moving cable packs compact and reduces the number of separate runs that have to travel with the axis. That arrangement also helps separate stationary cabinet wiring from the moving harness, which can simplify routing through drag chains and articulated joints. It is suited to equipment where both electrical continuity and cable flexibility are important during motion.

The assembly terminates on the drive side with a Series 915 8-pin female power connector that provides eight contacts for motor voltage, brake, and feedback conductors. Power cores with a cross-section of 0.75 mm² use tinned copper stranded wire and support a continuous load current of 13 A. At that conductor size, loop resistance is limited to ≤26.7 Ω/km, which helps reduce voltage drop over longer cable routes. Two separate signal pairs use a smaller conductor area of 0.34 mm², allowing compact routing while still supporting encoder transmission. The stranded construction also helps the conductors tolerate repeated bending better than a rigid solid-core design. The insulation system withstands a 4 kV test and maintains an insulation resistance of at least 500 MΩ·km, which helps limit leakage and signal interference in electrically noisy machinery.

The outer sheath uses PUR, which resists oils and abrasion in applications with continuous movement. The cable is rated for ≥5 000 000 flex cycles, and its overall diameter of 10.1 mm ±0.3 mm supports standardized clamp sizing and dense routing through cable carriers. A consistent outer diameter also helps maintain predictable bend behavior where several axis cables share the same carrier channel. Core insulation made from PP keeps the individual conductors separated and maintains dielectric strength during repeated thermal changes. This layout suits packaging lines, pick-and-place gantries, and other automation axes where cables are exposed to repeated bending, acceleration, and close-quarters installation.
