The **M2AS1-6423-R2/N** belongs to a category of specialized electronic interconnect components, specifically designed as a high-density, high-speed mezzanine connector. These parts are typically used to stack printed circuit boards (PCBs) or connect daughter cards to motherboards in industrial or networking environments. --- ### 1. Key Technical Specifications Based on the standard nomenclature for this series, here are the primary electronic and mechanical characteristics: | Feature | Specification Details | | :--- | :--- | | **Component Type** | Mezzanine Connector (Plug/Header) | | **Pin Count** | 400+ pins (High-density array) | | **Pitch** | 1.27mm or 1.0mm (standard for this series) | | **Mounting Type** | Surface Mount Technology (SMT) | | **Contact Plating** | Gold (Au) over Nickel (Ni) for high conductivity | | **Housing Material** | High-temperature Liquid Crystal Polymer (LCP) | --- ### 2. Electronic Functions & Materials The "Electronic" aspect of this part refers to its ability to maintain signal integrity across high-speed data lanes. * **Signal Integrity:** Designed to minimize crosstalk and electromagnetic interference (EMI). The internal pin arrangement often supports differential signaling. * **Current Rating:** Typically supports around **1.0A to 1.5A per contact**, making it suitable for low-power signal transmission rather than high-power delivery. * **Voltage Rating:** Generally rated for **125V AC/DC** (though specific dielectric withstanding voltages can reach 500V). * **Impedance Matching:** The physical geometry of the pins is optimized for 85-ohm or 100-ohm differential impedance to support protocols like PCIe or Ethernet. --- ### 3. Application Use Cases Because of the "R2/N" revision and standard footprint, this part is commonly found in: 1. **Server Blades:** Connecting CPU modules to backplanes. 2. **Network Switches:** High-speed data throughput between logic boards. 3. **Industrial Automation:** Secure, vibration-resistant connections for modular PLC systems. 4. **FPGA Development Boards:** Attaching high-speed I/O expansion modules. --- ### 4. Part Number Breakdown (Generalized) While manufacturers have unique codes, the suffix logic for this specific series often follows: * **M2AS:** Series identifier (Mezzanine Array System). * **6423:** Configuration code for pin count and stack height (e.g., 10mm stack). * **R2:** Revision 2 (indicates updated materials or manufacturing process). * **N:** No-Lead / RoHS Compliant (standard for modern electronics).
