The **M2AS1-A341-R2/N** is a specific technical part number typically associated with **M.2 SSD interface connectors** or specialized electronic sub-assemblies (often found in industrial computing or networking equipment like ADVANTECH systems). Based on the standard nomenclature for this component class, here is a breakdown of its electronic characteristics and structural parts. --- ### 1. General Specifications This part is an internal connector designed to facilitate high-speed data transfer between a motherboard and an M.2 form-factor module (such as an SSD or Wi-Fi card). | Feature | Specification | | :--- | :--- | | **Component Type** | M.2 (NGFF) Connector / Socket | | **Interface Standard** | PCIe (Gen 3/4) / SATA / USB | | **Pin Count** | 67-pin (Standard for M.2) | | **Mounting Type** | Surface Mount (SMT) | | **Keying** | Type A, B, or M (Specific to sub-model) | | **Pitch** | 0.50 mm | --- ### 2. Key Electronic Parts and Materials The performance of the M2AS1 series relies on high-quality materials to maintain signal integrity at high frequencies. #### A. Contact Terminals * **Material:** Phosphor Bronze or Copper Alloy. * **Plating:** Usually features gold plating (3u" to 30u") on the contact area to prevent oxidation and ensure low contact resistance over multiple mating cycles. * **Function:** Ensures the electrical path for high-speed differential pairs (TX/RX). #### B. Insulator Body * **Material:** High-temperature thermoplastic (e.g., LCP - Liquid Crystal Polymer). * **Function:** Provides structural rigidity and electrical isolation between the 67 pins. It is designed to withstand Reflow Soldering temperatures (up to 260°C). #### C. Solder Pegs / Grounding Tabs * **Material:** Stainless steel or tin-plated copper. * **Function:** These provide mechanical stability to the PCB, ensuring the connector doesn't lift during module insertion, and provide a grounding path to reduce EMI (Electromagnetic Interference). --- ### 3. Technical Drawing Characteristics The suffix **R2/N** often refers to specific revisions or packaging styles (e.g., Tape & Reel for automated assembly). * **Height:** Usually available in various stack heights (e.g., 3.2mm, 4.2mm, or 8.5mm) to accommodate components underneath the M.2 card. * **Orientation:** Right-Angle (Horizontal) insertion is the standard for this series. --- ### 4. Application Use-Cases * **Industrial PCs:** Used in controllers for automation. * **Embedded Systems:** Connecting NVMe storage in compact form factors. * **Networking Gear:** Providing slots for 4G/5G LTE modules or hardware encryption keys.
