Intro: Reliable Coaxial Connections Are the Backbone of Modern Vehicle Electronics
From GPS navigation to backup cameras, from satellite radio to ADAS sensors – coaxial connectors are everywhere in today’s vehicles. They carry high‑frequency signals with minimal loss and excellent noise immunity. As car systems become more data‑intensive (4K cameras, 5G telematics, real‑time diagnostics), the demand for high‑performance coaxial connectors is growing rapidly.
In this guide, you will learn:

Why LEADSIGN FAKRA connectors are the professional choice for automotive applications

FAKRA (Fachkreis Automobil) is the standardized coaxial connector system for automotive RF applications. The Z‑type is one of the 14 colour‑coded variants, typically used for specific antenna or sensor connections.
Feature | FAKRA Z‑Type (and FAKRA family) |
|---|---|
Impedance | 50Ω |
Frequency range | DC – 6 GHz (standard), DC – 20 GHz (Mini FAKRA) |
Mating cycles | ≥ 25 |
Operating temperature | -40°C to +105°C |
Sealing | IP67 optional |
Locking | Secondary lock + audible click |
Colour coding | 14 colours (Z‑type has a specific colour – typically light blue or according to application) |
Design features:
Plastic housing with mechanical keying – prevents mismating.
High‑quality materials (copper alloy terminals, gold or tin plating) for durability.
Robust lock mechanism – withstands vibration.
Faster data transfer: Supports high‑frequency signals (6‑20 GHz) needed for GPS, SDARS, 4K cameras, and 5G.
Low signal loss (attenuation): Coaxial construction (centre conductor, dielectric, shield) minimises signal degradation over long cable runs (5‑15 metres).
High return loss (low VSWR): Less signal reflection – cleaner data.
Vibration resistance: Secondary lock and colour‑coded keying keep connectors engaged even on rough roads.
EMI / RFI rejection: Double shielding (foil + braid) prevents interference from alternators, wipers, EV motors.
Corrosion resistance: Gold or tin plating on terminals protects against moisture, salt, and chemicals.
Temperature range: -40°C to +105°C – engine bay and exterior compatible.
Sealed options (IP67): For underbody and exterior antenna/camera connections.
Application | Coaxial connector type | Why |
|---|---|---|
GPS / GNSS antenna | FAKRA amber | 50Ω, low loss, colour‑coded |
Backup camera (AHD, CVBS) | FAKRA blue | Video signal, 6 GHz |
4K surround view camera | Mini FAKRA blue | 20 GHz, small form factor |
SDARS (satellite radio) | FAKRA white (or bordeaux) | 2.3 GHz |
4G/5G telematics antenna | FAKRA violet / Mini FAKRA violet | Low attenuation, double shielding |
Space‑saving design:
Standard FAKRA is already compact; Mini FAKRA is 80% smaller.
PCB‑mount and in‑line versions allow integration into tight dashboards, mirror housings, and small sensors.
Trend | Implication |
|---|---|
4K cameras on trucks, buses, and SUVs | Mini FAKRA (20 GHz) required – standard FAKRA’s 6 GHz may cause image loss over long runs. |
5G C‑V2X (cellular vehicle‑to‑everything) | 5G antennas need Mini FAKRA (violet) with low‑loss, double‑shielded coax. |
EV / hybrid | High EMI environment – coaxial shielding is critical for noise immunity. |
Pre‑terminated cables | Shops prefer LEADSIGN pre‑terminated FAKRA cables – no field crimping, guaranteed impedance. |
Multi‑port FAKRA modules | Integration of multiple antennas (GPS, 4G, SDARS) into one connector housing. |
