Guide to Buying FAKRA Plugs for Automotive Wiring Connector Types – Professional B2B Guide (2026)
Intro: The Right FAKRA Plug Ensures Reliable GPS, Radio, and Camera Performance
FAKRA (Fachkreis Automobil) plugs are the industry standard for automotive RF and high‑speed data connections. They are used in GPS antennas, satellite radio (SDARS), backup cameras, 4G/5G telematics, infotainment, and Bluetooth systems. With colour‑coded housings (14 colours), secondary locking, and 50Ω impedance, FAKRA plugs prevent mismating and ensure signal integrity. This guide covers FAKRA plug types, selection criteria, installation, maintenance, and common questions. For pre‑terminated, ready‑to‑install FAKRA cables, LEADSIGN offers custom lengths and full colour coding.
1. What Are FAKRA Plugs? – Purpose and Applications
Application | FAKRA colour | Frequency | Purpose |
|---|---|---|---|
GPS / GNSS antenna | Amber | 1.575 GHz | Navigation, positioning |
Backup camera (1080p/4K) | Blue | 1.5‑6 GHz | Rearview video |
SDARS (satellite radio) | White | 2.3 GHz | SiriusXM, DAB |
4G/5G telematics | Violet | 0.7‑6 GHz | Cellular connectivity, eCall |
AM/FM radio antenna | Bordeaux | 0.1‑108 MHz | Analogue radio |
USB / infotainment | Green | – | (not common, HSD used) |
Key features: Colour coding + mechanical keying prevent mismating (e.g., blue FAKRA will not fit amber socket). Secondary lock / CPA ensures vibration‑proof connection. IP67 sealing optional for exterior/underbody.
2. Types of FAKRA Plugs – Colour Codes and Styles
Colour | FAKRA code | Typical application |
|---|---|---|
Amber | C or H | GPS / GNSS antenna |
Blue | D or Z | Backup camera (AHD, CVBS, LVDS) |
White | K | SDARS (satellite radio) |
Violet | A | 4G/5G telematics |
Bordeaux | E | AM/FM radio antenna |
Green | I | USB / infotainment (rare) |
… plus 8 more colours | Various manufacturer‑specific |
Connector styles:
Straight – standard, for direct connection.
Right‑angle – for tight spaces behind dashboards or in mirror housings.
No‑load (dummy) – for sealing unused ports, no electrical connection.
Waterproof (IP67) – for underbody, roof antennas, exterior mirrors.
LEADSIGN offers pre‑terminated FAKRA cables in all 14 colours, any length (0.3m – 20m), straight or right‑angle, with IP67 optional.
3. How to Choose the Right FAKRA Plug – Selection Criteria
Factor | What to evaluate | Example |
|---|---|---|
Vehicle system | GPS → amber; camera → blue; telematics → violet | Blue FAKRA for backup camera |
Environment | Exterior/underbody → IP67 sealed | Roof GPS antenna → IP67 amber FAKRA |
Frequency | Up to 6 GHz (standard) or up to 20 GHz (Mini FAKRA) | 4K camera long run → Mini FAKRA blue |
Locking | Secondary lock required for vibration | All FAKRA have secondary lock |
Cable type | 50Ω coax (RG‑174, RG‑58, low‑loss) | Use low‑loss for >5m runs |
Installation method | Pre‑terminated (recommended) vs. field crimp | LEADSIGN pre‑terminated cables |
Pro tip: For field repairs, always use pre‑terminated FAKRA cables from LEADSIGN – field crimping FAKRA is difficult and often results in impedance mismatch.
4. Installation and Maintenance Tips
✅ Installation (using pre‑terminated cable)
Select correct colour – match function (amber=GPS, blue=camera).
Route cable – avoid sharp bends, heat, and moving parts.
Remove dust cap from connector (if present).
Push plug into socket until audible click and secondary lock engages.
Perform tug test – connector should not separate.
✅ Maintenance
Inspect periodically – look for corrosion, cracked housing, damaged seals.
Clean with contact cleaner – do not use water or WD‑40.
Replace damaged cables – do not attempt to repair centre pin.
Common installation mistakes:
Forcing mismatched colour – blue plug will not fit amber socket.
Leaving dust cap off – allows dirt ingress.
Field crimping without proper tool – causes impedance mismatch, signal loss.
5. 2026 Trends – Mini FAKRA and Higher Frequencies
Trend | Implication |
|---|---|
4K/8K cameras | Mini FAKRA (20 GHz) required – standard FAKRA’s 6 GHz may be insufficient for long runs. |
5G telematics | Mini FAKRA violet with low‑loss coax – field repair impossible; use pre‑terminated. |
Space‑constrained designs | Mini FAKRA is 80% smaller – fits thin dashboards, mirror housings. |
Pre‑terminated cables | Shops prefer LEADSIGN plug‑and‑play FAKRA – no crimping, guaranteed impedance. |
