### Y-CONC-R402S-RJ2U-2000-C: Technical Overview The **Y-CONC-R402S-RJ2U-2000-C** is a specialized electronic component, typically classified as a high-performance **Industrial RJ45 Connector Assembly** or an **Industrial Ethernet Interface**. These parts are designed for rugged environments where standard consumer-grade RJ45 connectors would fail due to vibration, EMI, or mechanical stress. --- ### 1. Component Specification Table | Feature | Description | | :--- | :--- | | **Product Category** | Industrial Ethernet Connector / PCB Mount RJ45 | | **Series** | Y-Con (Yamaichi Electronics) | | **Configuration** | Shielded RJ45 with integrated Power Contacts | | **Data Rate** | Up to Cat 5e (1000 Base-T depending on specific wiring) | | **Mounting Type** | Through-hole / PCB Mount | | **Shielding** | Full Metal Shielding (Nickel/Tin plated) | | **IP Rating** | Usually IP20 (Internal) or IP67/68 when used with Y-Con cover | --- ### 2. Key Electronic Parts & Features #### A. Integrated Power Contacts Unlike standard RJ45 connectors that only handle 8 pins for data, the **Y-Con** series often features **additional power pins**. This allows for the transmission of power (up to 2.1A or more) separately from the data lines, reducing noise and increasing power delivery capabilities compared to standard PoE. #### B. Shielding and Grounding * **EMI Protection:** The "RJ2U" designation often refers to the specific shielding configuration, designed to ground high-frequency noise to the PCB chassis. * **Material:** The housing is typically made of high-temperature thermoplastic (UL94V-0) with a copper alloy shield. #### C. Contact Architecture * **Plating:** The contacts are generally gold-plated (often 30μ" or 50μ") to prevent oxidation and ensure low contact resistance over thousands of mating cycles. * **Mechanical Stability:** The "R402S" suffix usually denotes a specific physical orientation (e.g., 90-degree right angle) and locking mechanism style to ensure the cable remains seated under vibration. --- ### 3. Application Use Cases 1. **Industrial Automation:** Connecting PLCs (Programmable Logic Controllers) to factory networks. 2. **Robotics:** Handling data and power transmission in robotic arms where movement is constant. 3. **Vision Systems:** High-speed data transfer for industrial cameras that require a stable power source. --- ### 4.
