Mini-FAKRA 4-in-1 | The High-Speed and Miniaturization Challenge

With the rapid development of intelligent connected vehicles, connectors face higher requirements — especially in miniaturization, high-frequency high-speed transmission, and reliability. The widespread adoption of LiDAR, 8MP high-definition cameras, autonomous driving systems, and in-vehicle Ethernet is gradually replacing traditional automotive architectures.

Due to their larger size and limited bandwidth, conventional FAKRA connectors can no longer meet the high data-transmission standards of next-generation smart vehicles. To address this shift, we began developing the Mini-FAKRA 4-in-1 connector. Using a micro-coaxial cable (MCA) solution, it is more compact in structure, significantly reduces signal loss, and is better suited to high-density cabling environments.

Mini-FAKRA already meets the stringent communication performance requirements of L3-and-above autonomous driving — fully aligned with the “higher frequency, higher speed, smaller size” direction of automotive electronics.

Traditional FAKRA remains a mature, cost-effective choice for low- and mid-frequency applications: its standardized design reduces development complexity, minimizes signal interference, and prevents mis-insertion, with standardized maintenance and replacement processes.

Beijida’s Mini-FAKRA 4-in-1 retains these core advantages while cutting volume by more than 80% — with stronger performance that fully supports L3+ autonomous driving, making it the preferred connection solution in the miniaturization trend.

TE-compatible version. Our BJD Mini-FAKRA 4-in-1 solution adopts a differentiated structural technology path while remaining compatible with mainstream standards, building an independent technology system.

Rosenberger-interface-compatible version. Our BJD Mini-FAKRA 4-in-1 solution features independently optimized key structures while remaining compatible with mainstream standards. Geometric optimization compensates for manufacturing tolerances, and a one-piece outer conductor simplifies the structure and eliminates assembly interfaces, delivering enhanced performance.

BJD’s Mini-FAKRA production covers the entire process in-house — from precision stamping, injection molding, and assembly to testing.

• Professional harness equipment: fully automatic jacket stripping, terminal crimping, and copper crimping.
• Seven CCD inspection systems: 360° all-around harness inspection with no blind spots, ensuring product consistency and reliability.
• 30 operators → 1 machine: work that previously required 30 people is now completed directly by a single harness machine — one harness every 5.5 seconds, adaptable to multiple models and specifications.
