### WJFK-6C2-R: Electronic Parts & Specifications The **WJFK-6C2-R** is a high-performance, shielded **RJ45 Jack (Connector)** commonly used in networking hardware. It is specifically designed for high-speed data transmission and PCB (Printed Circuit Board) mounting. --- ### 1. Key Technical Specifications Below are the primary electronic and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Connector Type** | RJ45 (8P8C) | | **Mounting Type** | Through-hole (PCB Mount) | | **Orientation** | Right Angle (Side Entry) | | **Shielding** | Fully Shielded (Metal Shell) | | **Contact Plating** | Gold over Nickel | | **Performance Category** | Typically Cat5e or Cat6 compatible | | **Number of Ports** | 1 Port | --- ### 2. Internal Components & Materials The assembly of the WJFK-6C2-R consists of several critical electronic and structural parts: 1. **Housing:** Made of high-temperature thermoplastic (usually UL94V-0 rated) to withstand wave soldering processes. 2. **Contact Pins:** Phosphor bronze base material with selective gold plating. The gold ensures low contact resistance and prevents oxidation over time. 3. **Shielding (EMI/RFI):** A copper alloy or stainless steel outer shell that provides grounding and protects the signal from electromagnetic interference. 4. **LED Indicators:** (Depending on the specific sub-model variant) Often includes integrated Green/Yellow LEDs for link and activity status. 5. **Internal Magnetics (Transformers):** In many "JFK" series connectors, there are internal "MagJack" components (isolation transformers and common mode chokes) to filter noise and provide electrical isolation between the cable and the PHY chip. --- ### 3. Pin Configuration (Typical 8P8C) For standard Ethernet applications, the pins are utilized as follows: | Pin Number | Function (T568B Standard) | | :--- | :--- | | 1 | Transmit + (TX+) | | 2 | Transmit - (TX-) | | 3 | Receive + (RX+) | | 4 | Reserved / DC | | 5 | Reserved / DC | | 6 | Receive - (RX-) | | 7 | Reserved / DC | | 8 | Reserved / DC | --- ### 4. Application Areas * **Networking Gear:** Routers, Switches, and Hubs. * **Industrial PC:** Motherboards and Interface cards. * **Telecom:** Modems and VoIP devices. * **Embedded Systems:** Single-board computers (SBCs) requiring wired internet connectivity. ---
