Product Description:

The 8ECF00X4.1241C-0 is a flexible servo-drive link manufactured by B&R Automation for its ACOPOS P3 Cables series. This preterminated assembly transports control signals and auxiliary power between an ACOPOS P3 drive and distributed I/O hardware, simplifying installation and ensuring reliable motion commands in industrial automation cells. By combining fine-gauge pairs and shielded supply leads in a single, drag-chain-ready jacket, it reduces panel space and assembly time. It is intended for moving cable applications where signal stability and flexibility are both required.

Mechanical endurance is rated for 30,000,000 flex cycles, allowing continuous operation in energy chains. An overall braid provides 85% shield coverage, and the cable has a 6 mm ±0.2 mm outside diameter that fits standard strain-relief bushings. Conductors may not be bent tighter than a 19 mm single bend radius, protecting copper strands during reciprocating travel. Inside, four 0.14 mm² signal pairs and four 0.35 mm² supply cores provide the required cross section while keeping weight low. Static loop values are limited to a signal resistance of 134 Ω/km and a supply resistance of 55 Ω/km, so voltage drop remains low on long runs. Insulation resistance is greater than 200 MΩ·km, helping prevent leakage to ground. A dielectric strength of 0.5 kV between wire and shield and a 1 kV wire-to-wire test voltage verify insulation integrity. The PUR outer jacket material resists oils, coolants, and weld spatter.

For dynamic carriages, the assembly withstands up to 6 g acceleration without conductor fatigue. The drive end uses a 9-pin female DSUB that screws into standard controller brackets. Field modules connect through an 8-pin male Mini I/O with a push-pull latch to help prevent vibration loosening. These matched connectors maintain signal integrity across the full motion range without additional ferrules.
