Product Description:

The 8ECH0003.1B41C-0 is a hybrid power-and-signal cable manufactured by B&R Automation and assigned to the ACOPOS P3 Cables series. It is intended for drive assemblies where a single harness supplies motor power and encoder feedback. Using one cable for both functions reduces separate routing paths between the drive and the motor. The combined layout also reduces the number of individual cable runs across moving axes and machine joints. That arrangement helps conserve panel space in automated cells and modular machine frames.

The conductor package is arranged as 4x 1.5 mm² + 2x 0.75 mm² + 2x 24 AWG, so the four larger cores transfer phase current while the smaller pairs carry control and differential encoder signals. In fixed routing, the cable can carry up to 20.2 A, and that load reaches the drive through a pre-molded 8-pin female Speedtec hybrid connector. A separate 8-pin male Mini I/O plug on the encoder side preserves signal quality and supports a compact feedback connection. This connector arrangement keeps power transmission and feedback termination organized at their respective connection points. When both connectors are mated, the assembly reaches IP66/67 protection, and insulation between conductors withstands up to 4 kV in electrically noisy environments.

The PUR outer sheath is formulated for cable-carrier operation and repeated movement in dynamic routing. It tolerates up to 3,000,000 continuous flex cycles, chain accelerations of 50 m/s², and horizontal carrier speeds of 300 m/min without cracking. Power conductors exhibit a maximum loop resistance of 13.3 Ω/km, helping minimize voltage drop on long axes. Overall insulation resistance stays above 500 MΩ·km for consistent signal quality during continuous machine operation. Fewer than 500 mating cycles are recommended for the Speedtec interface to preserve locking torque and sealing ring integrity.
