The **M2AS1-6244-R2** is a specialized high-speed connector component, typically part of the **M-Series** or high-density interconnect systems used in enterprise networking and telecommunications. These parts are engineered to facilitate high-signal integrity for blade servers, switches, and backplane applications. --- ### Technical Specifications and Overview | Feature | Specification Details | | :--- | :--- | | **Component Type** | High-Density Mezzanine/Backplane Connector | | **Series** | M2AS / High-Speed Interconnect | | **Pin Configuration** | Multi-row high-density arrangement | | **Mounting Type** | Surface Mount (SMT) or Press-fit (depends on sub-variant) | | **Contact Material** | Copper Alloy with Gold over Nickel Plating | | **Signal Integrity** | Optimized for Differential Pairs (High Gbps support) | --- ### Key Electronic Attributes #### 1. Signal Integrity (SI) Design The "6244" configuration is specifically designed to minimize **crosstalk** and **insertion loss**. In high-speed electronics, these connectors use a specific shielding geometry to ensure that data rates (often exceeding 10-25 Gbps per channel) remain stable without electromagnetic interference. #### 2. Physical Architecture * **Pitch:** Usually features a fine pitch (e.g., 1.27mm or 1.00mm) to maximize I/O density in a small PCB footprint. * **Durability:** Rated for high mating cycles, ensuring the physical gold-plating layer does not wear down, which would increase resistance. #### 3. Lead-Free Compliance (R2 Suffix) The **-R2** suffix generally denotes a revision or compliance standard: * **RoHS Compliance:** Indicates the part is lead-free and meets environmental safety regulations. * **Revision 2:** May indicate a physical improvement in the housing material (Liquid Crystal Polymer) to withstand higher reflow soldering temperatures. --- ### Common Applications 1. **Blade Servers:** Connecting CPU modules to a common backplane. 2. **Networking Switches:** Interfacing line cards with the main switching fabric. 3. **Industrial Computing:** Used in ruggedized environments where high-vibration resistance and high data throughput are required simultaneously. --- ### Example Footprint Logic (Pseudocode representation) While specific pinouts depend on the manufacturer's datasheet (e.g., Molex, Amphenol, or Tyco), the footprint generally follows this logic: ```json { "part_number": "M2AS1-6244-R2", "pin_mapping": { "Rows": ["A", "B", "C", "D", "E", "F"], "Columns": 40, "Signal_Types": ["Differential Pair", "Ground Plane", "Power"] } } ```
