The **M2AS1-4231-R2/N** is a specific part number typically associated with high-density, multi-layer printed circuit board (PCB) assemblies or backplane connectors used in industrial networking and telecommunications. Below is a breakdown of its technical characteristics and typical specifications. --- ### 1. Component Overview This component is generally categorized as a **Backplane Connector** or a **High-Speed Mezzanine Connector**. It is designed to facilitate the connection between a daughtercard and a motherboard in rack-mounted systems. ### 2. Technical Specifications The following table highlights the common parameters for this series of electronic parts: | Feature | Specification | | :--- | :--- | | **Connector Type** | Mezzanine / Board-to-Board | | **Pitch** | Typically 1.0mm or 1.27mm | | **Pin Configuration** | Multi-row (often 4 rows) | | **Mounting Type** | Surface Mount (SMT) or Through-Hole | | **Material** | High-temperature Thermoplastic (UL 94V-0) | | **Contact Plating** | Gold over Nickel | | **Current Rating** | 0.5A to 1.0A per contact | ### 3. Key Electronic Characteristics * **Signal Integrity:** Designed for high-speed differential signaling to minimize crosstalk and electromagnetic interference (EMI). * **Impedance Matching:** Usually rated for 85Ω or 100Ω differential impedance to match standard communication protocols. * **Durability:** Rated for high mating cycles (typically 100–500 cycles) due to the robust plating on the contact pins. ### 4. Part Number Decoding (Typical) While manufacturers vary, the suffix and prefix usually denote specific mechanical variations: * **M2AS:** Series identifier (Mezzanine 2-row/4-row Assembly). * **4231:** Internal configuration code (Pin count or physical dimensions). * **R2:** Revision 2 or Tape and Reel packaging. * **N:** "No peg" or specific environmental compliance (e.g., Lead-Free/RoHS). --- ### Common Applications 1. **Telecommunications:** Base stations and switching centers. 2. **Data Servers:** High-density blade servers for inter-board communication. 3. **Industrial Automation:** Modular PLC (Programmable Logic Controller) systems.
