Coaxial cables used in vehicles are mainly for transmitting high-frequency signals such as those for automotive cameras (especially HD cameras), radar, GPS navigation, wireless antennas, satellite antennas, vehicle communication (V2X), and in-car entertainment systems.
Common Types of Automotive Coaxial Cables:
| Name | Description | Features |
|---|---|---|
| FAKRA Coaxial Cable | The most common automotive coax cable with a plastic locking housing | Waterproof, vibration-resistant, widely used for GPS, antennas, cameras, and radios |
| HSD (High-Speed Data) Coaxial Cable | For high-speed data transmission like LVDS video, USB, Ethernet | 4-shielded coaxial design, excellent shielding, and anti-interference |
| Mini-FAKRA | A miniaturized version of FAKRA | Smaller and lighter, ideal for ADAS, HD cameras, and space-constrained areas |
| FAKRA SMB | FAKRA connector with an internal SMB interface | Compact size for tight spaces |
| Rosenberger HFM | Next-generation high-speed coaxial connector | Supports up to 20 Gbps, used in autonomous driving cameras and radar |
| RG Series (e.g., RG174) | Used in older or low-speed signal transmission | Cost-effective, suitable for low-frequency signals |
Automotive Coaxial Cable Standards:
- LVDS (Low-Voltage Differential Signaling) – For HD cameras
- Ethernet over Coax (EoC) – Ethernet transmission via coaxial cable
- MOST, GVIF, APIX – For multimedia and video data transmission in vehicles
Typical Applications:
- GPS Antenna – FAKRA to RG174 coax
- Backup/Rear Cameras – HSD or Mini-FAKRA
- Millimeter-Wave Radar – Rosenberger HFM
- Vehicle 5G Antenna – Mini-FAKRA or high-frequency FAKRA
- HD Surround View Systems – HSD 4-core coaxial cables
