The **10226-R20CS** refers to a high-performance, high-density I/O connector, specifically part of the **3M™ Mini Delta Ribbon (MDR)** series. These components are widely used in industrial automation, telecommunications, and medical imaging for high-speed data transmission. --- ### 1. Technical Specifications The part number follows a specific nomenclature used by 3M to define its physical and electrical characteristics. | Feature | Specification | | :--- | :--- | | **Connector Type** | Receptacle (Solder Plug) | | **Series** | Mini Delta Ribbon (MDR) | | **Number of Positions** | 26 Pins | | **Pitch** | 0.050" (1.27 mm) | | **Mounting Type** | Board Mount / Through Hole (Right Angle) | | **Contact Material** | Copper Alloy | | **Contact Plating** | Gold over Nickel | | **Current Rating** | 1 Ampere | --- ### 2. Key Physical Components The 10226-R20CS is engineered for durability in harsh environments. * **Ribbon Contacts:** Unlike standard pin headers, MDR connectors use a "ribbon" contact system. This design provides multiple points of contact, reducing signal noise and increasing mechanical stability. * **Shielded Shell:** The "R" series typically features a metal shroud or EMI (Electromagnetic Interference) shielding, which is critical for maintaining signal integrity at high frequencies. * **Board Locks:** The "CS" suffix often indicates specific mounting hardware, such as board locks or screws, designed to secure the connector to a PCB (Printed Circuit Board) during the soldering process and throughout the product's lifecycle. --- ### 3. Common Applications Due to its reliability and high pin density, this part is found in several professional-grade electronic systems: 1. **Camera Link Standard:** Most high-end industrial cameras use 26-pin MDR connectors to transmit massive amounts of image data to frame grabbers. 2. **Servo Drives:** Used in motion control systems for feedback signals between motors and controllers. 3. **Medical Equipment:** Found in ultrasound and MRI machines where compact, shielded cabling is required to prevent interference. 4. **Networking:** High-speed data links in routers and switches. --- ### 4. Comparison: MDR vs. Standard SCSI | Feature | MDR (10226-R20CS) | Standard SCSI | | :--- | :--- | :--- | | **Size** | Ultra-Compact | Bulky | | **Density** | High (1.27mm pitch) | Low/Medium | | **Speed** | Optimized for High-Speed | Standard Low-Speed | ---
