1. What are HSC and HSL Connectors?
HSC and HSL are compact shielded high-speed data connector systems found in automotive camera, display, and infotainment applications. They are not universal 50 Ω coaxial connectors like FAKRA. Instead, they are shielded interconnect systems that can support multiple protocols — LVDS, USB 2.0, GVIF, IEEE 1394, and camera serial links — depending on the exact supplier, part number, and vehicle platform specification.
Key characteristics that apply to both systems:
- Compact form factor: Small connector bodies suitable for camera modules, mirror housings, and tight infotainment spaces
- Fully shielded: Metal shielding for EMC performance in the vehicle environment
- Mechanical coding: Keyed housings to prevent mismating on the assembly line
- High-speed data: Support for digital data rates typically up to 1 Gbps or higher, depending on the specific connector series
Despite the similar names, HSC and HSL are different connector systems from different suppliers. Understanding which one you are dealing with requires checking the exact part number, not assuming based on appearance.
2. HSC Connector System (Amphenol)
HSC (High-Speed Connector) is Amphenol's shielded automotive interconnect system, typically using 0.50mm square terminals. It is designed for high-speed data applications in vehicles including:
- LVDS camera links
- USB 2.0 connectivity
- IEEE 1394 (FireWire) — legacy infotainment
- Digital camera serial interfaces
HSC connectors feature a fully shielded metal body, mechanical keying/coding to prevent mismating, and support data rates of 1 Gbps and above depending on the specific connector series. The exact pin count, terminal arrangement, and supported protocol vary by part number.
3. HSL Connector System (TE Connectivity)
HSL (High Speed Link) is TE Connectivity's 0.50mm pitch high-speed data connector system. Key features include:
- 0.50mm pitch terminals: Compact design for space-constrained applications
- Mechanical coding: Keyed housings to prevent mismating on the assembly line (number of codes varies by series — check supplier datasheet)
- Supported protocols: USB 2.0, LVDS, GVIF (Gigabit Video Interface) — depending on the specific connector variant
- Data rate: Up to 1 Gbps, depending on the connector series and cable assembly design
HSL connectors are commonly found in automotive camera, display, and infotainment wiring. Available pin configurations vary by part number — 4-position connectors are common for camera and display LVDS links, but other configurations exist.
All trademarks and connector family names are used for identification and compatibility reference only.
4. HSC / HSL vs FAKRA: Different Connector Ecosystems
HSC/HSL and FAKRA are different connector ecosystems, not substitutes for each other. FAKRA is a standardized 50 Ω RF coaxial connector (DIN 72594-1) with a center pin and outer shell. HSC/HSL are compact shielded high-speed data connector systems using 0.50mm terminals — they do not have a coaxial center pin.

5. How to Identify an HSC or HSL Connector
Visual identification alone is unreliable. The most reliable method is to find the connector part number molded into the housing and compare against the supplier datasheet (Amphenol for HSC, TE Connectivity for HSL).
For a step-by-step identification process and pin assignment lookup, see HSC / HSL Pinout Guide: Why Customer Drawings Matter.
When in doubt, send us a clear photo of the connector face, housing markings, and the mating connector for identification.
6. How to Specify an HSC / HSL Cable Assembly
To request a cable assembly quote, you will need: the mating connector part number, pin assignment or sample cable, signal type, cable type and length, sealing level, and test requirements.
For a detailed specification checklist, see HSC / HSL Pinout Guide: Why Customer Drawings Matter.
Frequently Asked Questions
Q: What are HSC and HSL connectors?
A: Compact shielded automotive high-speed data connector systems for camera, display, USB, LVDS, GVIF, and similar in-vehicle links. Not universal 50 Ω coax connectors. Pinout, impedance, and protocol depend on the exact supplier and part number.
Q: What is the difference between HSC and HSL?
A: Different suppliers — Amphenol HSC typically uses 0.50mm square terminals (LVDS, camera, USB, IEEE 1394). TE HSL uses 0.50mm terminals with up to 6 codings (USB 2.0, LVDS, GVIF). They are not variants of each other.
Q: Are HSC and FAKRA the same type?
A: No. FAKRA is a 50 Ω RF coaxial connector (DIN 72594-1) with center pin + shell. HSC/HSL are shielded high-speed data interconnect systems. They are different connector ecosystems — do not assume interchangeability.
Q: How do I identify an HSC or HSL connector?
A: Find the part number molded into the housing. Compare against the supplier datasheet. Check for terminal type — 0.50mm square/blade terminals vs. coax center pin. When in doubt, send us a photo of the connector face and markings.
Q: Can Veycord make HSC / HSL cable assemblies?
A: Yes. Send the mating connector part number, pin assignment or sample cable, cable length, and application. We will confirm feasibility, connector availability, and lead time for your specific requirement.
