The **M2AS1-6122-R** is a specific part number typically associated with high-performance **M.2 (NGFF) Connectors**, often manufactured by companies like **UDE (Universal Microelectronics)**. These components are critical in modern computing for interfacing SSDs, Wi-Fi modules, and LTE/5G cards with motherboards. --- ### 1. Key Technical Specifications Based on the standard nomenclature for this series, here are the primary electrical and physical characteristics: | Feature | Specification | | :--- | :--- | | **Connector Type** | M.2 (Next Generation Form Factor / NGFF) | | **Orientation** | Right Angle / Surface Mount (SMT) | | **Number of Pins** | 67-Pin (Standard for M.2) | | **Pitch** | 0.50 mm | | **Keying** | Typically "M-Key" (for PCIe x4 SSDs) or "B-Key" | | **Height** | 4.2mm - 6.0mm (varies by specific sub-dash number) | | **Data Rates** | Supports PCIe Gen 3, Gen 4, and SATA 3.0 | --- ### 2. Electronic Components & Construction The "electronic" part of this connector consists of several high-precision elements designed for signal integrity: 1. **Contact Base Material:** Usually a **Copper Alloy** for high conductivity and flexibility. 2. **Plating:** * **Contact Area:** Gold plating (typically 15μ" or 30μ") to prevent oxidation and ensure low contact resistance over multiple mating cycles. * **Solder Tail Area:** Matte Tin over Nickel to ensure high-quality solder joints during the SMT Reflow process. 3. **Housing:** High-temperature Liquid Crystal Polymer (LCP) or Nylon, capable of withstanding the heat of lead-free soldering. 4. **Grounding:** Integrated metal "ears" or tabs that are soldered to the PCB ground plane to reduce EMI (Electromagnetic Interference). --- ### 3. Application Use Cases The M2AS1-6122-R is commonly found in the following hardware: * **Laptops & Ultrabooks:** Main storage interface for NVMe SSDs. * **Industrial PCs:** Compact storage or communication module expansion. * **Networking Gear:** Used for pluggable LTE or 5G modem modules. * **Edge Computing Devices:** High-speed data buffering interfaces. --- ### 4. Part Number Breakdown (Typical) While manufacturers vary slightly, the code generally follows this logic: * **M2:** M.2 Series Connector. * **AS1:** Product sub-category (Angle/SMT type). * **6122:** Dimensional code (referring to pin count and height). * **R:** Packaging indicator (usually "Reel" for automated pick-and-place assembly).
