Based on the part number **M2AS1-4111-R2/Q**, this component belongs to a specific series of industrial or telecommunication connectors, likely a **Modular Jack (RJ45)** or a specialized **SFP/SFP+ Cage** assembly, often manufactured by companies like **UDE (Universal Device Electronics)**. Below is the technical breakdown of the electronic and structural characteristics typically associated with this part series. --- ## Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | Integrated Connector (often with Magnetics) | | **Form Factor** | Small Form-factor Pluggable (SFP) / RJ45 Hybrid | | **Port Configuration** | 1x1 (Single Port) | | **Mounting Type** | Through-hole (THT) or Press-fit | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **EMI Shielding** | Full Metal Shielding with Grounding Tabs | --- ## Key Electronic Components ### 1. Integrated Magnetics (MagJack) If this is the RJ45 variant, it contains internal transformers and common mode chokes. These components perform three vital functions: * **Isolation:** Protects the PHY chip from voltage spikes on the network cable (typically up to 1500V). * **Signal Conditioning:** Filters out noise to ensure data integrity over long distances. * **Impedance Matching:** Ensures the 100-ohm differential signal matches the transmission line. ### 2. LED Configuration The "4111" portion of the suffix often dictates the LED colors and positions. * **Left LED:** Green (Link/Activity) * **Right LED:** Yellow (Speed/Status) * **Circuitry:** Standard current-limiting resistors are required on the PCB side, as the LEDs inside are typically simple diodes. ### 3. Physical Construction (The "R2/Q" Suffix) * **Plating:** Gold plating on contacts (usually 30μ" or 50μ") to prevent oxidation and ensure low contact resistance over thousands of mating cycles. * **Housing:** High-temperature thermoplastic (UL 94V-0 rated) suitable for wave or reflow soldering. * **Shielding:** Nickel-plated copper alloy cage to minimize Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI). --- ## Application Use Cases 1. **Networking Hardware:** Switches, routers, and gateways. 2. **Industrial PC (IPC):** Providing ruggedized Ethernet connectivity. 3. **Storage Systems:** High-speed data transfer interfaces (NAS/SAN). ---
