Product Description:

The 8ECR0015.1121C-0 cable is built by B & R Automation as part of the ACOPOS P3 Cables series and is intended for servo-axis installations that link ACOPOS P3 drives with motors and encoders inside automated production cells. Its hybrid layout carries both feedback and power conductors. This allows one routed line to manage motor position signals and power needs while maintaining electromagnetic compatibility in moving cable chains.

The cable uses a strand arrangement of 3 x 2 x 24 AWG (19 x 0.127), a geometry that separates the three twisted signal pairs from the power cores to keep crosstalk low. Tinned copper stranded wire serves as the conductor material, giving high flexibility and corrosion resistance, while the maximum loop resistance is limited to ≤86 Ω/km to minimize voltage drop over long runs. Six dedicated signal lines carry encoder channels, and a special thermoplastic layer surrounds each conductor for thermal and dielectric stability. Overall insulation resistance is rated above 200 MΩ·km, and a braided foil with ≥90% shield coverage blocks external noise that could disturb high-resolution feedback. Between individual cores, the design withstands a 1.5 kV wire-to-wire test voltage, supporting safe separation between power and instrumentation circuits during transient events.

At the terminations, a 12-pin female springtec circular connector mates with the drive, while an 8-pin Mini I/O encoder connector attaches to the feedback device. Mechanical endurance is verified for ≥3,000,000 flex cycles in energy-chain duty at a chain velocity up to ≤4 m/s, so position repeatability is not degraded by continual motion. A tough PUR outer jacket resists cutting fluids and abrasion without sacrificing bend radius. Inside moving carriers or fixed routing, the six shielded pairs and the tinned conductors maintain low-noise transmission and reliable power delivery during sustained factory operation.
