The **M2AS1-5132-R** is a specific part number typically associated with high-speed interface connectors, most commonly found in **M.2 (NGFF) SSD slots** or similar modular interface applications. These components are critical for establishing reliable electrical connections between a motherboard and peripheral modules. --- ### 1. Component Overview The M2AS series generally refers to **M.2 Card Edge Connectors**. These are surface-mount (SMT) components designed to accept M.2 cards (SSDs, Wi-Fi modules, etc.). | Feature | Specification Details | | :--- | :--- | | **Connector Type** | M.2 (Next Generation Form Factor - NGFF) | | **Mounting Type** | Surface Mount (SMT) / Right Angle | | **Pitch** | 0.50 mm | | **Keying** | Typically "M" Key (PCIe x4/SATA) or "B" Key | | **Height** | Usually 3.2mm (indicated by the "32" in the suffix) | --- ### 2. Technical Characteristics These connectors are engineered to handle high-frequency signals while maintaining a small footprint. * **Signal Integrity:** Designed to support PCIe Gen 3, Gen 4, and SATA 3.0 protocols with minimal crosstalk. * **Contact Material:** Typically copper alloy with gold plating on the contact area to prevent oxidation and ensure low contact resistance. * **Pin Count:** Usually 67 pins (standard for M.2). * **Mechanical Durability:** Rated for approximately 60 to 100 mating cycles. --- ### 3. Pinout Logic and Keying The M2AS series uses "Keys" (notches in the connector) to prevent the wrong type of card from being inserted. | Key | Interface Supported | Common Usage | | :--- | :--- | :--- | | **B Key** | SATA / PCIe x2 | Older SSDs, WWAN modules | | **M Key** | PCIe x4 / NVMe | High-speed NVMe SSDs | | **E Key** | PCIe / USB / SDIO | Wi-Fi and Bluetooth modules | --- ### 4. Circuit Integration Example In a PCB layout, the M2AS1-5132-R requires a specific landing pattern for its 0.5mm pitch pins. ```c // Conceptual pin grouping for M.2 M-Key (Simplified) Pins 1-11: Ground / 3.3V Power Pins 12-19: Reserved / Config Pins 21-33: PCIe Lane 3 & 2 (Differential Pairs) Pins 35-49: PCIe Lane 1 & 0 (Differential Pairs) Pins 51-57: Clock Signals (REFCLK) Pins 59-66: 3.3V Power ``` --- ### 5. Common Applications * **Laptops/Ultrabooks:** Primary storage slots for NVMe SSDs. * **Industrial PCs:** Compact data logging modules. * **IoT Gateways:** Housing for cellular or Wi-Fi communication cards.
