Based on the model number provided, the **M2PHS2L-2D-R2** typically refers to a high-speed, high-density **M.2 (NGFF) Connector** designed for industrial and computing applications. These components are critical for interfacing SSDs, wireless modules, and other expansion cards to a motherboard. --- ## 🛠️ Technical Specifications & Electronic Characteristics The "R2" usually indicates a specific revision or a "Right Angle" orientation with specific height clearances. Below are the typical electronic and physical attributes for this type of connector: | Feature | Specification | | :--- | :--- | | **Connector Type** | M.2 (Next Generation Form Factor - NGFF) | | **Pin Count** | 67-Pin / 75-Position | | **Pitch** | 0.50 mm | | **Keying** | Likely **B-Key** or **M-Key** (specific to the '2D' designation) | | **Mounting Type** | Surface Mount (SMT), Right Angle | | **Voltage Rating** | 50V AC/DC | | **Current Rating** | 0.5A per pin | | **Operating Temperature** | -40°C to +85°C | --- ## ⚡ Key Electronic Parts & Design Features ### 1. Contact Material and Plating * **Base Material:** Usually a high-performance copper alloy (Phosphor Bronze or Beryllium Copper). * **Plating:** Gold plating is standard on the contact area (often 15µ" to 30µ") to ensure low contact resistance and prevent oxidation over high-speed data transmission. ### 2. High-Speed Signal Integrity * Designed to support **PCIe Gen 3 or Gen 4**, SATA 3.0, and USB 3.0. * The internal geometry is engineered to maintain **impedance control** (typically 85Ω or 100Ω) to minimize signal reflection and crosstalk. ### 3. Solder Tabs (Anchors) * The "R2" series often includes metallic "nails" or solder tabs on the sides of the housing. These provide mechanical strain relief to ensure the connector does not rip off the PCB during the insertion or removal of the M.2 card. ### 4. Housing Material * Made of High-Temperature Thermoplastic (LCP - Liquid Crystal Polymer). This allows the part to withstand **Reflow Soldering** temperatures (up to 260°C) without warping. --- ## 🔍 Part Number Breakdown (Typical) While manufacturers vary, the code usually breaks down as follows: * **M2:** M.2 Series. * **PH:** Plug/Header (Female Connector). * **S2L:** Likely refers to a "Slim" profile or a specific height (e.g., 2.3mm or 3.2mm). * **2D:** Dual-sided or specific Keying configuration. * **R2:** Revision 2 or Right-Angle orientation. ---
