Product Description:

The 8ECM0004.1031C-0 cable is supplied by B & R Automation within the ACOPOS P3 Cables series. It is a hybrid power and signal lead intended to link ACOPOS P3 servo drives to associated motor modules inside automated machinery. By combining power conductors and feedback pairs in one shielded assembly, the product simplifies cabinet wiring and supports deterministic motion control in distributed drive layouts.

The assembly ships in a fixed length of 4 m, giving predictable voltage drop and attenuation for axis runs inside standard machine frames. When the mated connector is fastened, the coupling attains an ingress rating of IP66/67, so washdown fluids or airborne dust do not reach the contacts. The PUR outer jacket withstands oils and continuous drag-chain motion, while the internal tinned copper strands handle a maximum line potential of 1000 VAC across the four power cores. Steady-state copper losses are limited by a power-conductor resistance of 26.7 Ω/km, and the separate signal pairs carry encoder data with a loop resistance of 56 Ω/km. Each power core has a 0.75 mm² cross-sectional area, and each signal wire has a 0.34 mm² cross-sectional area. Together, they use a layout of four 0.75 mm² power conductors plus two twisted pairs for feedback. Polypropylene insulation and an aluminum-laminated braid provide primary and secondary shielding between power and logic layers.

For continuous motion in energy chains, the cable is rated for 5,000,000 bending cycles without conductor breakage. The dielectric system maintains not less than 500 MΩ·km insulation resistance, helping keep leakage current below drive fault thresholds in humid environments. A factory-crimped 8-Pin Female Series 915 Power Connector provides keyed mating and strain relief, and its metal shell bonds to the overall shield for low-impedance grounding. The cable has a dielectric strength of 4 kV between the shield and cores as well as between individual wires, supporting the stated operating voltage.
