Product Description:

The 8BCH0004.1111A-0 is a hybrid motor cable manufactured by B&R Automation as part of the 8BC ACOPOS Cables series. Designed for dynamic machine axes, it conveys drive power, auxiliary supply, and feedback signals between an ACOPOS servo drive and its motor through one sheath to simplify routing inside moving assemblies. By combining these functions in one cable, it helps keep cable runs organized where repeated motion and limited installation space make separate leads less practical. This arrangement also reduces the number of individual connections that must pass through the same moving path.

Its mechanical construction centers on a 13 mm ±0.4 mm overall diameter that fits standard drag-chain clips while protecting the conductors during continuous motion. The chain-rated design is verified for at least 3,000,000 flex cycles, enabling high-speed indexing without conductor fatigue. A PUR sheath resists oils, coolants, and abrasion, and the power cores use a 1.5 mm² cross-section to carry motor phase current. Separate 0.75 mm² supply cores energize the holding brake, while two twisted signal groups, 2 × 0.30 mm² and 4 × 0.15 mm², handle encoder, temperature, and identification lines. The orange jacket improves cable visibility and helps distinguish motion wiring from neighboring harnesses.

The cable terminates on the motor side with a 13-pin female Speedtec hybrid motor connector that groups phase, brake, and sensor paths. The drive end uses a 9-pin male DSUB connector for feedback conductors, while nine auxiliary contacts complete the hybrid interface so no separate encoder cable is required. When mated, the assembly attains an IP66/67 protection level against dust and high-pressure water. Each core sustains a dielectric stress of 4 kV in the wire-to-wire test, and overall insulation remains above 200 MΩ·km after flex testing. These electrical properties help maintain stable signal transmission and dependable motor power in servo systems exposed to continuous motion.
