RJ45 connectors with integrated LEDs are common in Ethernet ports across routers, switches, industrial controllers, and embedded systems. These LEDs, driven by the Ethernet PHY, provide quick visual feedback for:
⚠ Note: Behavior is highly dependent on PHY configuration and may vary by design. Always consult the PHY datasheet for specific LED control logic.
| LED State | Common Interpretation |
|---|---|
| Solid Green | Link at 100 Mbps (typical) |
| Blinking Yellow | Data activity present |
| Solid Orange | Often used to denote 1 Gbps |
| Off | No link or power issue |
LINK-PP supports full LED customization, including:
Example: Industrial-grade connectors may use Orange/Green to clearly distinguish 100 Mbps and 1 Gbps links in high-noise environments.
Custom codes like E-G/Y, W-G/G, Bi-color, or N/N (no LED) are embedded in the part number suffix for quick identification.
(e.g., LPJG0933HENL = Green/Yellow LED combo)
For optimal hardware integration, ensure:
| Benefit | Description |
|---|---|
| Quick Troubleshooting | LED indicators simplify link and activity diagnostics |
| Reduced BOM | No need for external LEDs and routing |
| Better Aesthetics | Clean integration with product design |
| Customization | Match your application’s logic and visual needs |
Integrated LEDs are more than cosmetic—they are essential for visibility, diagnostics, and efficient deployment. With LINK-PP’s flexible customization, you can define the LED behavior, color, and positioning to match your system’s requirements precisely.
