The **M2AS1-5222-R** is a specific part number typically associated with high-performance **M.2 (NGFF) connectors**, often manufactured by companies like **Foxconn** or similar electronic component vendors. These connectors are designed to interface M.2 cards (such as SSDs or Wi-Fi modules) with a motherboard or PCB. --- ### 1. Technical Specifications Below are the general technical parameters for this type of component: | Feature | Specification | | :--- | :--- | | **Interface Type** | M.2 (Next Generation Form Factor - NGFF) | | **Keying** | Typically **M-Key** (Common for PCIe/NVMe SSDs) | | **Pin Count** | 67-Pin or 75-Position | | **Pitch** | 0.50 mm | | **Mounting Type** | Surface Mount (SMT) | | **Orientation** | Right Angle / Horizontal | | **Operating Voltage** | 50V AC/DC | | **Current Rating** | 0.5A per pin | --- ### 2. Physical Characteristics * **Standoff Height:** The "R" or specific suffix often denotes a specific height (e.g., 2.25mm or 3.2mm) to provide clearance for components located on the underside of the M.2 module. * **Material:** High-temperature thermoplastic housing (LCP) capable of withstanding lead-free reflow soldering processes. * **Plating:** Gold plating on contact areas to ensure high conductivity and prevent oxidation over high-speed data cycles. --- ### 3. Application Use Cases The M2AS1 series is primarily used in computing hardware to facilitate high-speed data transfer: 1. **Storage:** Connecting NVMe or SATA M.2 Solid State Drives. 2. **Connectivity:** Housing Wi-Fi, Bluetooth, or WWAN (4G/5G) modules. 3. **Industrial PCs:** Used in compact embedded systems where space is at a premium. --- ### 4. Mounting & Footprint The part is designed for **Automated Optical Inspection (AOI)** and pick-and-place assembly. It features: * **Solder Pegs:** Mechanical tabs that provide structural integrity to the PCB, ensuring the connector doesn't rip off during module insertion/extraction. * **Alignment Bosses:** Small plastic pegs on the bottom to ensure the connector is perfectly centered on the PCB pads before soldering. ---
