The part number **M2AS1-6424-R2/N** typically refers to a high-speed, high-density mezzanine connector, often associated with **Amphenol** or similar manufacturers in the telecommunications and server hardware industry. These components are designed for high-performance computing (HPC) environments where board-to-board connectivity requires high signal integrity. --- ### Technical Specifications Overview | Feature | Specification Details | | :--- | :--- | | **Component Type** | Mezzanine Connector (Board-to-Board) | | **Pin Configuration** | 64 Pins (standardized layout) | | **Mounting Type** | Surface Mount (SMT) | | **Orientation** | Vertical / Straight | | **Application** | High-speed data transfer (PCIe Gen 4/5, Ethernet) | | **Plating** | Gold over Nickel (standard for reliability) | --- ### Key Electronic Features #### 1. Signal Integrity The "R2" designation often refers to a specific revision or performance tier optimized for **Return Loss** and **Crosstalk** reduction. These connectors are engineered to handle differential signaling at speeds exceeding 25-56 Gbps per channel. #### 2. Mechanical Design * **Plug/Receptacle:** This part functions as either the male or female half of a mezzanine system. * **Stack Height:** The dimensions of this part dictate the physical gap between two parallel Printed Circuit Boards (PCBs). * **Polarization:** The housing is keyed to prevent incorrect mating, which protects the sensitive pins from mechanical damage. #### 3. Material Composition * **Insulator:** High-temperature thermoplastic (capable of withstanding Reflow Soldering). * **Contacts:** High-conductivity Copper Alloy. * **Suffix "/N":** This usually denotes a specific packaging type (e.g., Tape & Reel) or a lead-free/RoHS compliant version. --- ### Typical Use Cases * **Server Blades:** Connecting CPU boards to I/O expansion modules. * **Networking Gear:** Used in high-speed switches and routers. * **Medical Imaging:** Transferring large data sets between sensor boards and processing units. * **Storage Systems:** SSD controller board interfaces. ---
