8BCH0025.1312A-0
The B & R Automation 8BCH0025.1312A-0 hybrid motor cable, part of the CM16 Motor Cables series, embodies a robust single-cable solution engineered for demanding industrial automation environments. Designed to interface seamlessly with servomotors featuring a 400 V supply, this cable supports a rated power of 785 W and a rated torque of 2.5 Nm at a rated speed of 3000 rpm, ensuring efficient power transmission for precision motion control. Featuring a hybrid motor connector with PUR insulation, the assembly integrates both power and encoder signal lines in a single sheath, simplifying installation and reducing cable clutter. The cable's outer jacket provides oil resistance and protection against microbes and coolants, while its halogen-free composition enhances safety and environmental compliance. With a circular Speedtec connector design housing 13 pins, and a copper braid plus inner foil shielding structure, the unit ensures reliable signal integrity even in high-electromagnetic-interference settings.
Performance characteristics of the 8BCH0025.1312A-0 are defined by a peak torque of 7.5 Nm and a rated current of 2.85 A, with current capacity capped at 30 A by its hybrid connector for consistent operation. Its natural convection cooling method eliminates the need for external fans, reducing maintenance and noise. The integrated encoder interface supports a singleturn, 4096 increments resolution, delivering precise feedback for high-accuracy motion applications. Mechanical robustness is further reinforced by a shaft diameter of 14 mm interface and a rotor moment of inertia of 0.68 x 10^-4 kgm², facilitating dynamic response and reduced settling times. The cable’s construction includes both foil shielding and a copper braid, providing a combined shield for both power and signal conductors to withstand up to 4 kV test voltages between wire/wire and wire/shield. Color-coded stranded tinned copper wires in supply lines simplify identification and wiring.
Engineered with an IP65 protection class, this hybrid cable resists dust ingress and water jets, ensuring reliable operation in harsh industrial settings. Its bend radius of at least 121 mm under dynamic conditions preserves cable integrity and extends service life, making it suitable for high-acceleration drag-chain applications. The flange mounting connection and UL certification for power conversion equipment guarantee straightforward integration with B & R Automation's ACOPOS multi-inverter platforms, enabling true single-cable servo motor solutions. By combining power, feedback, and shielding in a compact assembly, the 8BCH0025.1312A-0 streamlines machine architectures in packaging, CNC machining, robotics, and other precision automation systems. Its balanced design prioritizes ease of installation, signal fidelity, and long-term reliability for continuous industrial operations.
