The **M2AS1-A341-R2** is a specialized high-speed connector component, typically part of the **M2AS Series** manufactured by companies like **JAE (Japan Aviation Electronics)**. These connectors are primarily designed for high-speed differential signal transmissions, such as those found in automotive infotainment, ADAS (Advanced Driver Assistance Systems), and telecommunications hardware. --- ### 1. Key Technical Specifications The part number follows a specific nomenclature related to its mechanical and electrical characteristics: | Feature | Specification | Description | | :--- | :--- | :--- | | **Connector Type** | Board-to-Board / High-Speed | Designed for mezzanine or perpendicular PCB connections. | | **Number of Pins** | Variable (Series dependent) | Specifically engineered for multi-lane data transfer. | | **Signal Integrity** | 10+ Gbps | Capable of handling USB 3.0, PCIe, and SATA signaling speeds. | | **Impedance** | 100 $\Omega$ (Differential) | Optimized for differential pair routing to minimize reflections. | | **Mounting Style** | Surface Mount (SMT) | Designed for automated pick-and-place assembly. | --- ### 2. Functional Electronic Components The "parts" or internal construction of this connector are engineered to maintain signal integrity in harsh environments: 1. **Contact Material:** Usually a copper alloy with gold plating over nickel. The gold plating prevents oxidation and ensures low contact resistance over thousands of mating cycles. 2. **Insulator/Housing:** High-temperature liquid crystal polymer (LCP). This allows the part to withstand the high heat of lead-free reflow soldering. 3. **Shielding Shell:** A metal outer casing (often stainless steel or brass) that provides EMI/EMC protection, preventing the high-speed signals from interfering with nearby wireless modules (GPS, LTE). 4. **Grounding Springs:** Integrated "fingers" that ensure a consistent ground path between the male and female connectors to reduce "crosstalk." --- ### 3. Application Use Cases This specific series is often found in the following electronic architectures: * **Automotive ECU:** Connecting the main processing board to the camera/sensor interface board. * **Networking Gear:** Used in routers and switches for daughter-card connections. * **Industrial Automation:** High-resolution display interfaces where signal noise must be strictly controlled. --- ### 4. Part Number Breakdown (General Pattern) While manufacturer-specific, the suffix **-R2** typically denotes: * **R:** Tape and Reel packaging (standard for SMT production lines). * **2:** A specific revision or the quantity per reel (e.g., 2000 units).
