Heilind Electronics has added the Molex High-Speed FAKRA-Mini (HFM) Interconnect System to its automotive connectivity portfolio, supporting modern vehicle electronics, including electric vehicle (EV) platforms. Compact, high-bandwidth interconnects are increasingly required as vehicle architectures consolidate compute resources, increase sensor density, and rely on higher data throughput.
The Molex HFM system supports data rates up to 28 Gbps and frequencies up to 20 GHz in a miniaturized form factor designed for space-constrained automotive environments.
Compared to traditional FAKRA connectors, HFM offers up to an 80% reduction in footprint, allowing higher device density without increasing wiring harness volume or PCB area, which is particularly relevant in platforms with limited packaging margin.
As vehicles integrate additional cameras, sensors, displays, and telematics modules, engineers face increasing challenges related to bandwidth, signal integrity, and reliable operation under vibration and temperature extremes. The HFM interconnect system is designed to support these requirements while maintaining mechanical robustness suitable for automotive applications.
The system supports automotive communication protocols including Ethernet, MIPI A-PHY, GMSL2/3, FPD-Link III/IV, APIX, and HDBase-T. These interfaces are commonly used in ADAS, autonomous driving functions, and centralized vehicle architectures that depend on real-time data from cameras, radar, lidar, and other sensors.
HFM connectors are available in single, dual, dual-stack, and quad configurations, providing flexibility for evolving vehicle network topologies. Integrated secondary locks, optional connector position assurance, and EMI shielding are intended to support long-term performance and assembly reliability.
The HFM interconnect system is applicable to automotive use cases including ADAS, autonomous driving systems, infotainment and high-resolution displays, in-vehicle networks, radar systems, sensor connections, and telematics. While not directly related to powertrain or charging systems, the technology aligns with the data-intensive electronic architectures used across current and advanced EV platforms.
