Product Description:

The 8ECF0025.1221C-0 cable is produced by B & R Automation within the ACOPOS P3 Cables series. It is a combined encoder and power connection designed to link ACOPOS P3 servo drives to motors in automated stations. The assembly routes differential feedback signals alongside low-current supply lines, allowing both functions to pass through a single flexible lead. Its compact geometry fits common drag-chain channels and helps reduce wiring density in packaging, material-handling, and assembly equipment. This combined layout also reduces the number of separate moving connections on the axis, which helps keep cable routing more compact in tightly spaced machines.

It uses a conductor matrix of 4x 0.14 mm² + 4x 0.35 mm², with four smaller conductors for encoder signals and four larger conductors for auxiliary power. The outer jacket measures 6 mm ± 0.2 mm in diameter, which supports routing through narrow energy tracks without excessive fill. Encoder feedback terminates in an 8-pin male Mini I/O plug that connects directly to B & R interface boards, while motor-side power is carried on a locking 12-pin female Series 615 connector for secure coupling. This arrangement keeps the cable slim while still accommodating both signal and auxiliary circuits in one jacket. Dynamic durability is rated for 30,000,000 flex cycles, and the cable requires a minimum bend radius of 19 mm to reduce conductor fatigue during repeated motion.

A molded coupling and outer sheath rated to IP66/67 block dust and high-pressure water when the connectors are mated. In dynamic service, the cable can travel at speeds up to 4 m/s and withstand accelerations of 6 g without jacket tearing or shield separation. The tinned-copper braid provides 85% optical coverage, which helps reduce emission and susceptibility so encoder signals remain stable near switching drives. The cable also supports operating voltages up to 30 V and insulation resistance above 200 MΩ·km for reliable transmission over the specified length.
