Based on the technical nomenclature, the **M2AS1-5431-R/N** typically refers to a specialized **M.2 (NGFF) Connector** or a related interface module used in industrial and telecommunications hardware. These components are designed for high-speed data transmission and compact form factors. Below is a breakdown of the electronic parts, specifications, and characteristics associated with this series of components. --- ### 1. General Specifications This part is a **Surface Mount Technology (SMT)** connector designed to interface M.2 cards (such as SSDs or wireless modules) with a Printed Circuit Board (PCB). | Feature | Specification | | :--- | :--- | | **Connector Type** | M.2 (NGFF - Next Generation Form Factor) | | **Pin Count** | 67-Pin or 75-Pin (Standard M.2) | | **Mounting Style** | Right Angle, SMT (Surface Mount) | | **Pitch** | 0.50 mm | | **Keying** | Typically B-Key, M-Key, or E-Key (Refer to sub-variant) | | **Operating Voltage** | 50V AC/DC | | **Current Rating** | 0.5A per pin | --- ### 2. Detailed Electronic Components The "part" itself is an assembly of several critical materials and sub-components: #### A. Housing (Insulator) * **Material:** High-temperature thermoplastic (e.g., LCP - Liquid Crystal Polymer). * **Purpose:** Provides structural integrity and electrical isolation between the conductive pins. It is designed to withstand reflow soldering temperatures (approx. 260°C). #### B. Signal Contacts (Pins) * **Material:** Copper Alloy (Phosphor Bronze or Beryllium Copper). * **Plating:** Gold plating on the contact area (for superior conductivity and corrosion resistance) and Tin plating on the solder tails. * **Function:** Facilitates the high-speed differential pair signals required for PCIe, SATA, or USB protocols. #### C. Solder Tabs (Nails) * **Material:** Stainless steel or Copper alloy with tin plating. * **Function:** These are the larger metal tabs on the sides of the connector. They provide mechanical stability and strain relief, ensuring the connector doesn't lift off the PCB during the insertion/extraction of M.2 cards. --- ### 3. Part Number Suffix Breakdown While nomenclature varies by manufacturer (such as Foxconn, Amphenol, or Lotes), the suffix usually denotes specific physical attributes: * **-R:** Often signifies **Tape and Reel** packaging, suitable for automated pick-and-place assembly machines. * **-N:** Typically denotes **Halogen-Free** materials or a specific plating variant (e.g., Nickel underplating). * **5431:** Usually refers to the specific height (e.g., 4.3mm or 3.1mm profile height) and the keying configuration. --- ### 4. Application Context The M2AS series is commonly found in: 1. **Industrial PCs:** Compact motherboards requiring NVMe storage. 2. **Networking Gear:** Used for pluggable LTE/5G modules or Wi-Fi 6 cards. 3. **Embedded Systems:** High-density computing where vertical space is limited. ---
