The part number **M2AVS-15316-R** refers to a high-speed, high-density backplane connector, specifically from the **AirMax VS** (Virtual Shielding) series originally developed by FCI (now part of Amphenol Communications Solutions). These connectors are designed for telecommunications, data networking, and server applications where high signal integrity and modularity are required. --- ### 1. Technical Specifications The AirMax VS system is unique because it achieves high speeds without the need for interleaved metal shields between differential pairs, reducing weight and cost. | Feature | Specification | | :--- | :--- | | **Series** | AirMax VS (Virtual Shielding) | | **Type** | Right-Angle Header / Receptacle | | **Column Count** | 10 to 15 Columns (Variant dependent) | | **Data Rate** | Up to 12.5 Gbps (per pair) | | **Impedance** | 100 Ohms (Differential) | | **Pitch** | 2.0mm or 3.0mm (depending on configuration) | | **Termination** | Press-fit (Eye-of-the-needle) | --- ### 2. Key Design Features * **Virtual Shielding:** Uses unique insert molding technology to control impedance and minimize crosstalk without heavy metal shields. * **Flexibility:** The "R" suffix typically denotes a specific orientation (Right Angle) or a RoHS-compliant revision. * **Scalability:** Allows for easy migration from 2.5 Gbps to 12.5 Gbps by maintaining the same footprint. * **Low Insertion Force:** Designed for easy assembly of large backplanes. --- ### 3. Pinout and Construction The connector is organized into **Differential Pairs**. A typical "15316" series part usually follows this internal logic: * **Signal Pins:** Optimized for low skew. * **Ground Pins:** Strategically placed to provide the "Virtual Shielding" effect. * **Housing:** High-temperature liquid crystal polymer (LCP). --- ### 4. Typical Applications 1. **Blade Servers:** Connecting blade units to the main chassis backplane. 2. **Switches/Routers:** High-speed data path connections. 3. **Medical Equipment:** High-resolution imaging data transfer. 4. **Storage Arrays:** Connecting drive arrays to controllers. --- ### 5. Part Number Breakdown (Generic) While internal manufacturer codes vary, the breakdown generally follows this logic: * **M2A:** Product Category (AirMax Series). * **VS:** Virtual Shielding Technology. * **15316:** Specific physical configuration (Number of positions/rows). * **-R:** Right-angle orientation / RoHS compliant.
