Wire‑to‑wire | Direct wire joining (lights, sensors) | Simple, secure | TE, Delphi, Molex |
Wire‑to‑board | Connecting wires to PCBs (ECUs, controllers) | Space‑saving, reliable | Molex, TE, JST |
Board‑to‑board | Linking two PCBs (ADAS, infotainment) | High density, fast data | TE, Molex, Hirose |
Special (FAKRA, HSD) | High‑speed data (camera, GPS, USB, Ethernet) | Impedance‑controlled, shielded | LEADSIGN |
4. 2026 Trends – What’s Changing in Connector Selection
Trend | Implication |
|---|---|
4K cameras on trucks and SUVs | Mini FAKRA (20 GHz) required – LEADSIGN is a key supplier. |
5G telematics (C‑V2X) | Mini FAKRA violet with low‑loss coax – pre‑terminated cables essential. |
EV / hybrid | High‑voltage (orange) connectors (do not touch). Low‑voltage data lines need extra EMI shielding. |
Pre‑terminated cables | Shops prefer LEADSIGN plug‑and‑play FAKRA/HSD cables – no field crimping, guaranteed impedance. |
5. How to Choose the Best Connector – Selection Criteria
Factor | What to consider | Preferred brand |

Weather conditions (heat, moisture, dust) | Sealed (IP67/IP69K) for engine bay/underbody | TE, Amphenol, Delphi |
Power requirements (current, voltage) | Match connector rating to circuit load | TE, Molex, Yazaki |
Data speed | 50Ω (FAKRA) for video/GPS; 100Ω (HSD) for USB/Ethernet | LEADSIGN |
Space constraints | Compact or miniature connectors | Molex, LEADSIGN (Mini FAKRA) |
Vibration | Secondary lock / CPA required | TE, Amphenol, FAKRA/HSD |
6. Why LEADSIGN – Your High‑Speed Data Connector Partner
