Product Description:

The 8ECF0007.1231C-0 is a flexible motor and feedback cable supplied by B&R Automation within its ACOPOS P3 Cables series. This pre-assembled harness transfers power and low-level signals between ACOPOS P3 servo drives and field-mounted motors or I/O modules, serving as a moving link inside energy-chain assemblies. Its construction supports continuous motion while maintaining stable electrical characteristics required for precise positioning and speed control in automated machinery, especially where one cable must handle repeated travel without interrupting communication.

The assembly is factory cut to a length of 7 m, allowing direct routing from the drive cabinet to the actuator without intermediate junctions. On the motor side, it terminates in an 8-pin female M12, A-keyed connector, while the drive end uses an 8-pin male mini I/O plug; the keyed formats help prevent cross-mating. The cable has a service life of ≥3,000,000 flex cycles, so the conductors can tolerate continuous chain motion. During operation, the cable may travel up to ≤4 m/s without exceeding jacket stress limits. Additional limits include a maximum acceleration of 60 m/s² and an outside diameter of 6 mm ±0.2 mm, which helps determine cable-carrier spacing and clamp fit.

A layer of copper/tin braiding encloses the core pairs, providing 360-degree electromagnetic shielding and supporting a wire-to-shield test voltage of 0.5 kV. The insulation maintains a resistance of >40 GΩ, helping preserve signal quality in high-humidity areas and during long periods of machine operation. Dynamic routing requires a moving bend radius larger than >47 mm, while single static bends should stay above 19 mm to reduce conductor fatigue. The power conductors use a cross section of 0.34 mm², while the signal pairs use 0.14 mm² to balance current capacity with flexibility. The cable weighs 0.41 kg and withstands a 1 kV wire-to-wire test voltage.
