Product Description:

The 8ECR0025.1111C-0 is a motor feedback cable supplied by B & R Automation as part of the ACOPOS P3 Cables series. It links ACOPOS P3 servo drives to encoders or resolvers so position signals can return to the controller during rapid machine cycles. This supports closed-loop motion control in packaging, printing, and assembly equipment where reliable feedback is needed for accurate axis regulation. Low-voltage differential signaling helps preserve feedback quality when the cable is routed beside moving machine components. This makes it suitable for axes that require fast correction of position and speed errors during continuous motion.

The conductor layout uses 3 × 2 × 24 AWG pairs, which helps limit crosstalk between the six signal lines and maintain stable impedance along the run. The cable has an outside diameter of 6.5 mm ±0.2 mm, and the shield uses copper braid with at least 90% coverage plus a foil shield to reduce interference from inverters and nearby power cables. Its compact diameter also helps the cable fit into drag chains and tight cable tracks without taking excessive space. Copper strands have a longitudinal resistance of no more than 86 Ω/km, which helps keep voltage drop low on longer runs. The PUR outer jacket is rated for more than 3,000,000 flex cycles in energy-chain operation. Encoder data is carried through an 8-pin male Mini I/O plug, while resolver signals can be terminated on a 12-pin female Speedtec interface, and both ends use molded connectors for vibration resistance.

During operation, the cable can bend down to a radius of 50 mm and tolerate machine acceleration up to 6 g without micro-cracking. The signal pairs are intended for an effective voltage of no more than 30 Veff, and the insulation resistance is greater than 200 MΩ·km to limit leakage. When connected, the coupling hardware seals to IP66/67, which helps protect the mated interface during wash-down on conveyors or handling robots. The sealed connection points are useful where moisture and spray are present around moving equipment. The PUR jacket also resists oils, coolants, and weld spatter in industrial environments.
