The **M2RS1-50-R** is a specific electronic component, typically categorized as a **Surface Mount (SMT) Header or Connector**, often associated with manufacturers like *Sullins Connector Solutions*. It is part of a high-density interconnect system designed for PCB (Printed Circuit Board) applications. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and electrical characteristics. | Parameter | Specification | | :--- | :--- | | **Series** | M2RS (Micro-miniature/High Density) | | **Pitch** | 2.00 mm (0.079") | | **Number of Pins** | 50 Positions | | **Row Configuration** | Single Row | | **Mounting Type** | Surface Mount (SMT), Right Angle | | **Plating** | Gold Flash or Full Gold (indicated by 'R' suffix variants) | | **Current Rating** | Typically 1A - 2A per contact | | **Termination** | Right Angle Solder Tails | --- ### 2. Key Electronic Components & Materials To understand the "electronic parts" of this connector, we must look at the materials that dictate its performance: * **Contact Material:** Usually a Copper Alloy (Phosphor Bronze or Brass). This ensures high conductivity and mechanical spring resilience. * **Insulator (Housing):** High-temperature Thermoplastic (e.g., Nylon 6T or LCP). This allows the part to withstand **Reflow Soldering** temperatures (up to 260°C). * **Contact Plating:** The "R" usually denotes a specific RoHS compliance and plating finish (Gold). Gold is used to prevent oxidation and ensure a low-resistance electrical path over time. --- ### 3. Functional Role in a Circuit The M2RS1-50-R acts as a **Passive Interconnect**. Its primary electronic functions include: 1. **Signal Integrity:** Providing a stable path for low-voltage data signals between two PCBs. 2. **Board-to-Board Connection:** Often used in a "Mother-Daughter" board configuration where one board sits at a 90-degree angle to the other. 3. **Low Profile:** The 2.00mm pitch makes it smaller than standard 2.54mm (0.1") headers, saving board space in compact electronics like IoT devices or handheld controllers. --- ### 4. Common Applications * **Industrial Controls:** Connecting PLC modules. * **Medical Devices:** Compact imaging or monitoring equipment. * **Consumer Electronics:** Internal connections for displays or peripheral modules. * **Automotive:** Low-current signal routing in dashboard electronics. ---
