The part number **M2AS1-6322-R2/Q** refers to a high-performance **M.2 (SATA/PCIe) SSD Connector** manufactured by **Lotes**. These components are critical in modern computing hardware, providing the interface between the motherboard and the storage module. --- ### 1. Component Specification Overview | Feature | Specification Details | | :--- | :--- | | **Manufacturer** | Lotes | | **Connector Type** | M.2 (Next Generation Form Factor - NGFF) | | **Keying** | M-Key (Typically for PCIe x4 NVMe SSDs) | | **Mounting Type** | Surface Mount (SMT), Right Angle | | **Pitch** | 0.50 mm | | **Height** | 3.20 mm (H3.2) | | **Pin Count** | 67 Pins | --- ### 2. Breakdown of the Part Number The alphanumeric string follows a specific coding logic used by Lotes for their connector series: * **M2AS1**: Refers to the M.2 Series (SATA/PCIe) product line. * **6322**: Specifies the physical dimensions and pin configuration (63 signifies the pin grouping, and 22 often refers to the connector height or revision). * **R2**: Indicates the revision level (Revision 2), often involving minor improvements in signal integrity or mechanical durability. * **Q**: This suffix usually refers to the packaging type (e.g., Tape & Reel for automated pick-and-place assembly) or specific plating requirements (Gold/Nickel). --- ### 3. Key Electronic Functions The M2AS1-6322-R2/Q serves as a bridge for several high-speed electronic protocols: 1. **High-Speed Signal Integrity**: Designed to support PCIe Gen 3 and Gen 4 speeds, ensuring minimal cross-talk and impedance mismatch across the 0.5mm pitch pins. 2. **Power Delivery**: The connector includes dedicated pins for 3.3V power supply to the SSD, along with multiple ground (GND) pins for stability. 3. **M-Key Architecture**: The physical notch (keying) prevents the insertion of incompatible modules, specifically ensuring that only M-Key compatible NVMe or SATA drives are utilized. --- ### 4. Common Applications * **Laptops/Ultrabooks**: Used as the primary storage slot to save vertical space. * **Motherboards**: Found in desktop PC motherboards (Z790, X670, etc.) for NVMe expansion. * **Industrial Computing**: Integrated into SBCs (Single Board Computers) for rugged storage solutions.
