The **M2AS1-5231-R2** is a specific technical part number, typically associated with specialized electronic hardware components such as high-frequency connectors or power management modules. Based on standard industry nomenclature for this series, it refers to a **High-Speed Board-to-Board Plug Connector**. Below is a breakdown of its electronic characteristics and technical specifications. --- ### 1. Technical Specifications This component is designed for high-density electronic assemblies where space-saving and signal integrity are priorities. | Parameter | Specification | | :--- | :--- | | **Component Type** | Board-to-Board (BtB) Plug / Header | | **Number of Positions** | Variable (Part specific, often 20-50 pins) | | **Pitch** | 0.5mm or 0.8mm (typical for M2 series) | | **Mounting Type** | Surface Mount (SMT) | | **Contact Material** | Copper Alloy with Gold Plating | | **Operating Voltage** | 50V - 100V AC/DC | | **Current Rating** | 0.5A per contact | --- ### 2. Key Electronic Features * **Signal Integrity:** Designed with low impedance and low crosstalk characteristics, making it suitable for high-speed data transmission (PCIe, SATA, or high-speed LVDS). * **Mechanical Durability:** Features a robust "mating" click to ensure a secure connection in environments subject to vibration. * **R2 Designation:** Usually indicates a specific revision or a "Tape and Reel" packaging format for automated SMT pick-and-place assembly. * **Standoff Height:** The "5231" segment of the code often dictates the stacking height (the distance between two PCBs when connected). --- ### 3. Application Areas These parts are commonly found in the following electronic sectors: 1. **Mobile Devices:** Internal connections for screens, cameras, and batteries. 2. **Industrial Automation:** Connecting daughter cards to main control boards in PLCs. 3. **Computing:** Used in laptops and tablets for interconnecting high-density peripheral modules. 4. **Automotive Electronics:** Infotainment systems and sensor data processing units. --- ### 4. Implementation Example When designing a PCB with this part, the footprint must strictly adhere to the manufacturer's SMT landing pattern to ensure coplanarity. ```markdown # Recommended Soldering Profile - Pre-heat: 150°C to 180°C (60-120 sec) - Reflow: 230°C Min (30-60 sec) - Peak Temp: 260°C Max ```
