Product Description:

The 8BCM0020.3034C-0 is a prefabricated motor and drive cable produced by B & R Automation for the 8BC ACOPOS Cables series. It combines servo power conductors and low-level feedback lines in one assembly to streamline wiring between ACOPOS drive modules and associated field devices. Integrated shielding, molded ends, and a sealed outer jacket let the cable be routed quickly on factory floors while maintaining deterministic communication in automated machinery cells.

Electrical capacity starts with the composite conductor set of 4x 0.75 mm² + 2x 2x 0.34 mm², a layout that separates power pairs from differential signal pairs and keeps the outer diameter compact. A total reach of 20 m covers cabinet-to-axis distances on large production lines without intermediate junctions. Stranded tinned-copper cores support a continuous load of 8.5 A, and the eight contacts inside the molded plug allocate dedicated paths for phase, ground, and encoder lines. The gray PVC jacket resists abrasion and fits drag-chain tracks, while its sealing system meets the IP66/67 rating so the cable can operate in washdown and dusty areas. Dielectric integrity is verified by a wire-to-wire withstand test of 4 kV, limiting insulation failure when drives employ fast-switching IGBTs.

For termination, the assembly uses an 8-pin female Series 915 connector that mates directly with ACOPOS power modules and eliminates adapter loss. Power delivery in that plug uses the larger power conductors, and feedback travels on a shielded pair with a cross section of 0.34 mm² to maintain signal integrity. The cable weighs 4 kg, light enough for dynamic axis routing yet heavy enough to damp vibration. Chemical exposure is addressed by the jacket’s TM5 oil-resistance classification, and a 3 kV shield-to-jacket dielectric strength supplies an extra margin against ground faults during transients.
