Product Description:

The 8ECF0020.1231C-0 is a pre-assembled motion cable from B&R Automation's ACOPOS P3 Cables series. It connects servo drives to field devices in handling and gantry systems that need compact routing and dependable signal transfer. The cable carries power and feedback circuits in one assembly, which helps reduce wiring complexity on fast-moving axes.

Its conductor bundle uses 4 x 0.14 mm² + 4 x 0.35 mm², separating low-level signal paths from auxiliary conductors within a slim build. An outside diameter of 6 mm ±0.2 mm supports dense routing through cable carriers and crowded machine spaces. EMI control comes from copper/tin braiding with at least 85% coverage, which helps preserve signal quality near inverter-driven equipment. The field side terminates in an 8-pin female M12, A-coded connector, while the drive side uses an 8-pin male Mini I/O connection. The assembly is rated for 30 V DC operation and tolerates peak accelerations of 6 g during dynamic motion.

A PUR jacket resists cutting oils and chain abrasion while staying flexible in repetitive motion. The cable can be installed with a minimum bending radius of 19 mm in single-stroke applications, helping it fit into compact moving loops. In continuous travel, speeds up to 4 m/s support rapid-transfer axes without sacrificing cable management. Insulation resistance remains above 200 MΩ·km, which supports stable electrical performance over long service intervals. It also suits standard machine-tool chain profiles, making substitutions simpler in retrofit work.
