The **M2AS1-5112-R2** is a specialized high-speed connector, typically classified as an **M.2 (Next Generation Form Factor / NGFF)** socket. These components are fundamental 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 part series (often manufactured by vendors like **Lotes** or **Foxconn**), the technical breakdown is as follows: | Parameter | Specification | | :--- | :--- | | **Connector Type** | M.2 (NGFF) | | **Keying** | Likely **A-Key** or **E-Key** (Common for Wireless/IoT modules) | | **Mounting Type** | Surface Mount (SMT) / Right Angle | | **Number of Positions** | 67-75 Pins (Standard for M.2) | | **Height** | 4.2mm - 5.2mm (Series dependent) | | **Pitch** | 0.50 mm | | **Data Rates** | Supports PCIe Gen 3/4, USB 3.0, and SATA 3.0 | --- ### 2. Physical Construction The part consists of several critical electronic and mechanical elements: * **Housing:** High-temperature thermoplastic (UL94V-0 rated) designed to withstand reflow soldering temperatures. * **Contacts:** Copper alloy with selective **Gold Plating** on the contact area to ensure low electrical resistance and prevent corrosion over high-frequency signals. * **Solder Tabs:** Large metal "ears" on the sides provide mechanical stability, ensuring the connector doesn't rip off the PCB during module insertion or vibration. --- ### 3. Pinout and Signal Integrity The "Electronic" nature of this part revolves around its ability to handle high-speed differential pairs: 1. **Differential Pairs:** Specifically routed to handle impedance-controlled signals (usually 85Ω or 100Ω) for PCIe lanes. 2. **Power Delivery:** Dedicated pins for 3.3V rail supply to the module. 3. **Grounding:** Multiple ground pins are interspersed between signal pins to minimize **Crosstalk** and **EMI (Electromagnetic Interference)**. --- ### 4. Common Applications This specific part number is frequently found in: * **Laptops/Notebooks:** For Wi-Fi 6/6E cards. * **Industrial PCs:** For M.2 communication modules. * **IoT Gateways:** To interface with LoRa or Zigbee M.2 expansion cards.
