Product Description:

The 8ECM0020.1312C-0 is a combined power-and-signal lead produced by B&R Automation for the ACOPOS P3 Cables series. It connects ACOPOS P3 servo drives to matching motors, carrying three-phase power and low-level feedback through one routed assembly. Within industrial automation, this single-cable arrangement reduces panel wiring and simplifies installation on distributed motion axes. It also allows power and control connections to follow the same cable path, which helps keep moving assemblies more orderly.

At the drive end, the harness uses an 8-pin female speedtec motor connector. Four contacts deliver phase current, and four carry control signals, matching the cable’s eight-contact layout. Conductor sizing of 4 x 4.0 mm² + 2 x 0.75 mm² + 2 x 1.0 mm² keeps voltage drop low on the power pairs while reserving smaller cores for auxiliary circuits. These paths can carry 30 A continuously, and the insulation system tolerates 1000 VAC between conductors. A molded TPU jacket completes the outer sealing, and the cable has an IP66/67 rating. In drag-chain use, the construction endures ≥5,000,000 flex cycles without conductor breakage. The specified power-line resistance is 5.1 Ω/km or less, so added cable length introduces only limited losses.

When mounted in a drag chain, the cable is approved for traversing speeds up to 300 m/min and acceleration peaks of 50 m/s², making it suitable for fast-moving positioning systems. Even under these kinematic loads, the insulation resistance remains at ≥500 MΩ·km, which helps protect encoder signals from leakage current. The speedtec coupling is rated for fewer than 500 mating operations before replacement, which suits semi-permanent machine wiring where the assembly is installed once and then left in place. This operating profile fits applications in which the cable moves repeatedly during machine operation, but the connection points are not unplugged on a regular basis.
