HFM® - High-Speed FAKRA-Mini
Rosenberger HFM® is the best performing system of coaxial โMini-Coaxโ 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. Best cost is based on fully stamped and formed manufacturing processes and automated connector mounting and cable assembly. With HFM® the customer can count on an interface that accommodates future vehicle networks, applications and protocols.
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 โ in real time.
Rosenberger HFM® is compliant to all common automotive standards.

Connector Position Assurance - CPA prevents accidental disconnection of mated connectors
High-speed data connectors are being used more and more in driver assistance and autonomous driving systems.
As a result, the mating process must be more reliable and avoid accidental or uncontrolled disconnection of connectors. An improvement is the new additional CPA - Connector Position Assurance.
The CPA on the coupler side can be locked only, when the connector pair is fully mated. Accidental unlocking and disconnection is therefore impossible.
- The additional CPA enables reliable connection to be verified during the mating process
- The closed CPA prevents uncontrolled disconnection of the mated connector pair
- The new CPA is available as an option
