The **M2AS1-5222-R** is a specific electronic component typically categorized as a **Modular Jack (RJ45)** connector. These parts are fundamental in networking hardware for Ethernet connectivity. Below is a detailed breakdown of its specifications and electronic characteristics. --- ### 1. General Specifications This part is a high-performance integrated connector designed for telecommunications and data networking. | Feature | Specification | | :--- | :--- | | **Component Type** | RJ45 Modular Jack | | **Configuration** | 1x1 (Single Port) | | **Orientation** | Side Entry (Right Angle / Horizontal) | | **Mounting Type** | Through-Hole (THT) | | **Shielding** | Fully Shielded with EMI Tabs | | **LEDs** | Integrated (Typically Green/Yellow) | --- ### 2. Electronic & Material Composition The "electronic" performance of the connector is defined by its internal pins and shielding capabilities. #### A. Contact Interface * **Gold Plating:** The contact pins are usually plated with gold (often 30u" or 50u") to prevent oxidation and ensure low contact resistance over thousands of mating cycles. * **Material:** Phosphor Bronze is the standard base material for the pins due to its excellent elasticity and conductivity. #### B. Integrated Magnetics (MagJack) Most parts in this series are **MagJacks**. This means they contain internal circuitry to handle: * **Isolation Transformers:** Protects the equipment from voltage spikes on the network line. * **Common Mode Chokes:** Filters out electromagnetic interference (EMI) to ensure data integrity. * **Signal Conditioning:** Matches impedance for Ethernet standards (10/100/1000 Base-T). #### C. Shielding and Grounding The outer "metal can" (shield) is made of a copper alloy nickel-plated finish. This acts as a Faraday cage, preventing external radio frequency interference (RFI) from disrupting the signal and reducing the device's own emissions. --- ### 3. Pinout and Circuit Schematic While specific schematics vary by manufacturer (often brands like **UDOO**, **Belfuse**, or **HanRun**), the typical internal electronic layout follows this logic: ```cpp // Typical 10/100 Base-TX Internal Circuitry (RJ45 Side) (PCB Side) Pin 1 (TX+) <--- Transformer ---> Pin 1 (TD+) Pin 2 (TX-) <--- Transformer ---> Pin 2 (TD-) Pin 3 (RX+) <--- Transformer ---> Pin 3 (RD+) Pin 6 (RX-) <--- Transformer ---> Pin 4 (RD-) Pins 4,5,7,8 <--- Bob Smith Termination ---> Common Ground ``` --- ### 4. Application Use Cases * **Networking Gear:** Switches, routers, and hubs. * **Industrial PC:** Motherboards and embedded systems requiring Ethernet. * **IoT Gateways:** Providing wired internet stability for smart devices.
