The **M2AVS-4312-R/N** is a specialized high-speed electrical connector, typically part of the high-density interconnect families (like the SEARAY™ or similar mezzanine series) often manufactured by companies like Samtec. These components are designed for high-bandwidth applications where signal integrity and space-saving are critical. --- ### 1. Component Overview This part is a **Mezzanine Connector**, used to stack two Printed Circuit Boards (PCBs) parallel to each other. It is engineered to handle high-speed differential pairs while maintaining a low profile. ### 2. Technical Specifications Below are the typical electronic and mechanical characteristics associated with this specific part series: | Feature | Specification | | :--- | :--- | | **Part Type** | High-Speed Mezzanine Socket/Plug | | **Number of Positions** | 432 (based on the 4312 series naming convention) | | **Row Configuration** | 12 Rows | | **Pitch** | 1.27 mm (0.050") | | **Data Rate Capability** | Up to 28+ Gbps | | **Contact Material** | Copper Alloy with Gold Plating | | **Operating Temperature** | -55°C to +125°C | --- ### 3. Key Electronic Features * **Solder Charge Technology:** The "R/N" often refers to the attachment method. These connectors frequently use solder charges (small spheres of solder pre-attached to the leads) to ensure a reliable reflow process on high-density SMT (Surface Mount Technology) pads. * **Impedance Control:** Designed to maintain a **50-ohm single-ended** or **100-ohm differential** impedance to minimize signal reflection in high-speed circuits. * **Low Crosstalk:** The internal geometry is optimized to reduce electromagnetic interference (EMI) between adjacent signal pins, which is vital for PCIe Gen 4/5 or Ethernet applications. --- ### 4. Application Areas The M2AVS-4312 series is commonly found in the following environments: 1. **Data Centers:** High-end servers and blade computing. 2. **Telecommunications:** Network switches and routers. 3. **Medical Imaging:** High-speed data transfer from sensors to processing units. 4. **Military/Aerospace:** Ruggedized high-density computing modules. --- ### 5. Identification Code Breakdown (General) While specific to the manufacturer's catalog, the nomenclature generally breaks down as: * **M2AVS:** Product Series (Mezzanine High-Speed). * **43:** Total Pins per row / Size factor. * **12:** Number of rows. * **R/N:** Refers to RoHS compliance or specific packaging (Tape & Reel).
