Product Description:

8BCM0011.1034C-0 belongs to the 8BC ACOPOS Cables series from B&R Automation. It is a prefabricated combined power and signal cable for ACOPOS servo axes, allowing one cable run to replace separate motor and encoder lines. The assembly is intended for dynamic machine sections such as gantry axes, pick-and-place heads, and indexing tables where repeated movement requires high flex life. Factory-mounted connectors and color-coded conductors help simplify routing and keep cabinet layouts orderly.

The cable has a length of 11 m, so controllers can be mounted outside moving zones while still reaching the actuators. A nominal outer diameter of 10.1 mm ±0.3 mm fits common drag-chain clamps, and the internal cable set uses four 0.75 mm² power conductors plus two shielded 2 x 0.34 mm² signal pairs to reduce crosstalk. Tinned copper stranded wire supports flex performance, backed by a rating of ≥5,000,000 continuous flex cycles when the moving bend radius remains above 78 mm. The cable uses a molded 8-pin female Series 915 connector that mates with the motor socket without field crimping. A polyurethane jacket protects the bundle against cutting fluids, while an insulation resistance of ≥500 MΩ·km helps preserve feedback integrity. For washdown areas, the coupling has a sealing class of IP66/67.

Low loop resistance helps reduce drive losses. The power cores have a resistance of ≤26.7 Ω/km, while the measurement pairs have a resistance of ≤56 Ω/km. During dielectric testing, the wire-to-wire withstand voltage reaches 4 kV, which supports the use of three-phase servo power and encoder references in the same sheath. The connector is rated for fewer than 500 mating cycles, after which contact quality can degrade. At just 0.98 kg, the cable adds little mass to moving axes and helps support high acceleration without overloading carriage bearings.
