What is the difference between MDR and SDR camera link?
The difference between MDR (Micro-D Ribbon) and SDR (Standard Density Ribbon) in CameraLink cables primarily lies in their connector types, pin configurations, and usage scenarios. Here’s a detailed breakdown:
1. MDR (Micro-D Ribbon) Connector
Full Name: Micro-D Ribbon (MDR-26).
Pins: 26-pin (standard for CameraLink).
Design:
Compact, high-density connector.
Uses a ribbon cable with shielded twisted pairs (STP).
Usage:
Most common connector for standard CameraLink (Base/Medium/Full configurations).
Found in industrial cameras (e.g., Basler, FLIR) and frame grabbers.
Pros:
✅ Robust shielding for EMI resistance.
✅ Secure locking mechanism (screws or latches).
Cons:
❌ Bulkier than SDR in some cases.
2. SDR (Standard Density Ribbon) Connector
Full Name: Standard Density Ribbon (SDR-26).
Pins: 26-pin (same as MDR, but different physical layout).
Design:
Uses a flatter, more flexible ribbon cable.
Less dense than MDR, but still shielded.
Usage:
Older CameraLink systems or specific OEM applications.
Less common today (largely replaced by MDR or HD-26).
Pros:
✅ More flexible cable for tight spaces.
Cons:
❌ Less robust against EMI compared to MDR.
❌ Rare in modern systems.
Key Differences Summary
| Feature | MDR-26 (Micro-D Ribbon) | SDR-26 (Standard Density Ribbon) |
|---|---|---|
| Pin Count | 26-pin | 26-pin |
| Density | High-density (compact) | Standard density (flatter cable) |
| Shielding | Excellent (STP design) | Good, but less robust than MDR |
| Common Use | Industrial cameras, frame grabbers | Older/OEM systems |
| Locking | Screws/latches for secure fit | Less secure |
| Flexibility | Stiffer due to shielding | More flexible |
Which One Should You Use?
For modern CameraLink systems: MDR-26 is the default choice (better shielding and reliability).
Legacy systems: SDR-26 might appear in older setups, but replacements are often MDR.
HD-26 Alternative: Some newer systems use HD-26 (even higher density than MDR).
Practical Notes
MDR-26 Camera link cable is backward-compatible with SDR-26 in terms of pinout, but the physical connectors differ.
Always check your camera/frame grabber specs—most industrial cameras today use MDR.
