Product Description:

The 8ECR0010.1121C-0 is a low-voltage motion cable produced by B&R Automation for the ACOPOS P3 Cables series. It links ACOPOS P3 servo drives to motors or decentralized I/O modules. It carries power, feedback, and auxiliary signals through a single routed line in drag-chain or articulating cable track systems commonly used in industrial automation cells.

On the drive side, the cable uses a 12-Pin Female Series 615 main connector for motor phases, encoder feedback, and protective ground, while an 8-Pin Mini I/O auxiliary plug carries separate sensor or brake conductors. Internally, it uses a 3 x 2 x 24 AWG/19 construction, which indicates three individually shielded twisted pairs made from 19-strand tinned copper for flexibility and conductor strength. The cable has an outside diameter of 6.5 mm ±0.2 mm, which helps with routing through narrow energy chains and conduit fittings. A braided foil shield provides electromagnetic compatibility with at least 90% coverage, and the polyurethane jacket resists oils and weld spatter. Electrical performance includes tinned copper resistance of 86 Ω/km or less, a wire-to-wire dielectric test of 1.5 kV, and insulation resistance above 200 MΩ·km to support stable signal transmission across the full cable length.

The cable is rated for 30 Veff or less, which aligns it with Safety Extra-Low Voltage circuits used inside machines. The jacket withstands more than 3,000,000 continuous flex cycles when the cable moves with a bend radius of 50 mm or greater. Dynamic motion is limited to 4 m/s or less in linear travel, and acceleration is limited to 6 g to help protect the conductor bundle from microcracking during rapid indexing. This makes the cable suitable for high-cycle pick-and-place axes, gantries, delta robots, and similar systems that require uninterrupted power and feedback continuity.
