The **M2CEC-11502-R** is a specific electronic component typically categorized as a **Modular Jack (RJ45)** connector. These parts are integral to telecommunications and networking hardware. ### Product Overview The M2CEC series generally refers to integrated connector modules that often include internal magnetics (MagJack technology). These are used to provide the physical interface for Ethernet connections while handling signal conditioning and EMI suppression. --- ### Technical Specifications (Estimated) | Feature | Specification | | :--- | :--- | | **Connector Type** | RJ45 (8P8C) | | **Orientation** | Right Angle (Horizontal) | | **Number of Ports** | Single Port (1x1) | | **Magnetics** | Integrated (Transformers/Chokes) | | **LED Configuration** | Typically Dual (Left: Green/Yellow, Right: Green) | | **Shielding** | Metal Shield with EMI Tabs | | **Mounting Type** | Through-Hole (THT) | --- ### Key Electronic Components Inside the M2CEC-11502-R, several sub-components work together to ensure data integrity: 1. **Isolation Transformers:** Provides electrical isolation between the Ethernet cable and the PHY (Physical Layer) chip, protecting the device from static and surges. 2. **Common Mode Chokes:** Filters out electromagnetic interference (EMI) and noise from the differential signal pairs. 3. **Bob Smith Termination:** A resistor/capacitor network used to terminate unused wire pairs and the common mode signal to ground, reducing EMI emissions. 4. **Integrated LEDs:** Built-in status indicators that signify "Link" and "Activity" states directly on the connector face. ### Common Applications * **Networking Gear:** Routers, switches, and hubs. * **Industrial PC:** Motherboards and embedded systems. * **IoT Gateways:** Devices requiring a wired 10/100/1000 Base-T Ethernet connection. --- ### Example Schematic Implementation When designing a PCB for this part, the pinout typically separates the **Cable Side** (facing the RJ45 plug) from the **PHY Side** (facing the microchip). ```c // Typical Pin mapping for MagJack Connectors Pin 1: TD+ (Transmit Data Plus) Pin 2: TD- (Transmit Data Minus) Pin 3: RD+ (Receive Data Plus) Pin 4: NC (Termination) Pin 5: NC (Termination) Pin 6: RD- (Receive Data Minus) ```
