In the complex web of automotive technology, few components work as quietly yet critically as FAKRA connectors. Born from a collaboration between engineering experts at BMW, Huber-Suhner, and Rosenberger (with Huber-Suhner’s connector business merging into Rosenberger in 2010), FAKRA has evolved from a solution for car radio antennas to a universal standard in automotive RF connectivity. Let’s dive into why FAKRA connectors are indispensable in modern vehicles—and how they’ve shaped the future of in-car communication.
FAKRA, short for FAchKReis Automobil (a nod to its origins in a team of automotive specialists), began as a response to BMW’s need for reliable radio antenna connections. Today, it’s the go-to RF connector standard for automakers worldwide, thanks to its durability, ease of use, and adaptability.
Rosenberger, a key player in its development, has driven FAKRA’s evolution:
- 2000 (1st Generation): Built on the SMB interface, these early FAKRA connectors added a plastic housing to enable quick, stable assembly in vehicles—solving the challenge of secure in-car connections.
- 2004 (2nd Generation): Refined with standardized performance specs, later codified in ISO 20860-1. Machined via turning, these connectors set the bar for reliability.
- 2007 (3rd Generation): Cost-optimized without sacrificing performance. Made via stamping (or drawing, in some cases), they’re perfect for fully automated production—ideal for high-volume automotive manufacturing.
FAKRA connectors are engineered to meet strict ISO 20860 standards, making them a trusted choice for critical automotive systems:
- Electrical Specs: Handles frequencies from 0 to 4GHz, with a 50-ohm characteristic impedance and a 1A maximum current—perfect for high-frequency signals.
- Mechanical Strength: Boasts a locking force of ≥100N (ensuring connections stay tight) and a misinsertion resistance of ≥40N (preventing costly errors).
From classic car functions to cutting-edge tech, FAKRA connectors power it all:
- Wireless Signals: AM/FM radio, GPS navigation, vehicle-to-everything (V2X) communication (2–4GHz, including transmission), and remote controls.
- Video Signals: A star in advanced driver-assistance systems (ADAS), where they transmit high-quality video from cameras—critical for features like lane-keeping and parking assist.
- Dual Locking Mechanism: A secondary lock (usually purple) ensures terminals are fully seated and boosts retention—no loose connections here.
- Color-Coded & Mechanical Coding: 14 unique coding options (with matching colored housings) prevent misalignment during assembly. This “color + mechanical” safeguard eliminates costly mistakes.
- Waterproof Options: Waterproof harness-side connectors achieve IPX7/IPX9K ratings at the mating interface—ideal for harsh undercarriage or exterior camera setups.
- Cable Compatibility: Works seamlessly with popular cables like RG174, RTK 031, RG59, RG179, and RG58.
FAKRA connectors adhere to global benchmarks, including:
- Design Standards: ISO 20860, USCAR18
- Validation Standards: LV214, USCAR2, USCAR17
As cars grow smarter—with more sensors, connectivity, and ADAS features—reliable signal transmission becomes non-negotiable. FAKRA connectors deliver that reliability, combining decades of engineering expertise with adaptability for future tech. Whether you’re building EVs, luxury vehicles, or budget-friendly models, FAKRA ensures your in-car systems communicate flawlessly.
