HFM® - High-Speed FAKRA-Mini

Rosenberger HFM® is the next generation and best performing system of Mini-Coax coaxial connectors for the automotive industry. For frequencies up to 20 GHz, the intelligent modular system ensures fast transmission of high data rates up to 28 Gbps. Its innovative design addresses the growing requirement for cost savings as well as reduced weight and size. Delivering space savings of up to 80 % compared to conventional FAKRA connectors, the Rosenberger HFM® connector system allows various modules to be accommodated in the smallest possible footprint. 

The priority of autonomous driving and driver assistance systems is to ensure safety. It is required to determine exact positions, to continuously calculate routes and to detect and classify objects. High data volumes from several cameras, diverse sensors and navigation sources must be combined and transported for this purpose – in real time.

Compliant to global automotive standards USCar & LV 214.

Product Portfolio

  • CPA versions (Connector Position Assurance)

Connector Position Assurance –  CPA prevents the mated connectors from accidental unmating

High-speed data connectors are more and more used in safety applications like driver assistance and autonomous driving systems. In this consequence the mounting process must be more reliable. An improvement is the new additional CPA - Connector Position Assurance.
The CPA can not be activated, if connector is not complete mated, when mated, the operator has to close the CPA, if this is possible, the mating process was correct and safe.
