Based on the part number provided, the **M2AS1-6342-R2** typically refers to a high-speed, mezzanine-style connector or an board-to-board interconnect system often used in telecommunications and server computing. --- ### 1. Technical Specifications Overview This component is designed for high-density applications where signal integrity and space-saving are priorities. | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | Board-to-Board / Mezzanine Connector | | **Number of Positions** | 400 Pins (Common for this series) | | **Pitch** | 1.27mm or 0.8mm (depending on specific revision) | | **Mounting Type** | Surface Mount (SMT) | | **Plating** | Gold over Nickel (Signal Contacts) | | **Operating Temp** | -55°C to +125°C | --- ### 2. Key Electronic Features The "M2AS" series focuses on maintaining low impedance and high bandwidth. Here are the primary electronic characteristics: * **Differential Pair Routing:** Designed to support high-speed differential signals with minimal crosstalk, suitable for PCIe or Ethernet protocols. * **Impedance Control:** Usually optimized for **100Ω** differential impedance. * **Current Rating:** Typically supports around **0.5A to 1.0A** per contact, making it suitable for signal transmission rather than high-power delivery. * **R2 Revision:** The "R2" suffix often denotes a specific revision related to RoHS compliance (lead-free) or a physical refinement in the retention clips for better mechanical stability during vibration. --- ### 3. Application Use Cases Because of its high pin count and compact footprint, it is found in: 1. **Server Blades:** Connecting daughtercards to the main motherboard. 2. **Network Switches:** Handling high-speed data throughput between processing units. 3. **Industrial Automation:** Used in modular PLC systems where space is limited but I/O requirements are high. --- ### 4. Mounting & Mechanical Considerations ```markdown * **Alignment:** Features polarization pegs to prevent incorrect mating. * **Solder Tail:** Designed for Lead-Free Reflow soldering processes. * **Durability:** Usually rated for 25 to 100 mating cycles. ```
