The **M2AS1-6414-R/N** is a specific model of an **M.2 (NGFF) Connector**, typically used in computing and embedded systems to interface SSDs, wireless modules (Wi-Fi/Bluetooth), and other peripheral cards. --- ### 1. General Specifications The part number follows the industry standards for M.2 connectors, focusing on height, keying, and mounting style. | Feature | Specification | | :--- | :--- | | **Component Type** | M.2 (Next Generation Form Factor) Connector | | **Pitch** | 0.50 mm | | **Number of Positions** | 67 Pins | | **Mounting Type** | Surface Mount (SMT), Right Angle | | **Keying** | Key A (Commonly for Wireless/Combo modules) | | **Height** | 4.2mm (Nominal Profile) | --- ### 2. Breakdown of Electronic Parts & Materials The connector is composed of three primary electronic material groups: #### A. Contact Pins (The Conductive Path) * **Material:** Usually a Copper Alloy (Phosphor Bronze or Beryllium Copper). * **Plating:** Gold plating is applied to the contact area (usually 3µ" to 15µ") to ensure low contact resistance and prevent oxidation. The solder tails are often plated with Matte Tin for better solderability. * **Function:** Transfers high-speed signals (PCIe, USB, SATA) between the motherboard and the module. #### B. Insulator Body (The Housing) * **Material:** High-Temperature Thermoplastic (e.g., LCP - Liquid Crystal Polymer). * **Properties:** Must withstand reflow soldering temperatures (up to 260°C). It provides electrical isolation between the 67 pins. #### C. Solder Pegs / Hold-downs * **Material:** Stainless steel or Brass with tin plating. * **Function:** These are mechanical tabs on the sides that are soldered to the PCB. They provide structural integrity so that inserting/removing an M.2 card does not tear the signal pins off the board. --- ### 3. Electrical Performance Characteristics When integrating this part into a circuit, the following electrical limits apply: | Parameter | Rating | | :--- | :--- | | **Current Rating** | 0.5A per pin (Maximum) | | **Voltage Rating** | 50V AC/DC | | **Contact Resistance** | 55 mΩ Max | | **Insulation Resistance** | 500 MΩ Min | | **Dielectric Strength** | 300V AC for 1 minute | --- ### 4. Keying and Compatibility The **"Key A"** designation in this specific series means the notch is located at pins 8-15. This is electrically configured to support: * **PCIe x2** * **USB 2.0** * **I2C** * **UART** *Note: It is generally used for Wi-Fi, Bluetooth, and NFC cards rather than high-speed NVMe storage (which typically uses Key M).*
