The **Y-CONC-R402U-RJ2L-2000-B** is a specific industrial-grade cable assembly, typically associated with high-speed data transmission and harsh environment connectivity. This part is commonly manufactured by **Yamaichi Electronics** as part of their **Y-Con** series. --- ## 1. Component Overview This part is a specialized RJ45-based industrial Ethernet cable assembly. The "Y-Con" system is designed to provide IP20 to IP67 protection (depending on the housing) while maintaining standard Ethernet pinouts. ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Connector Type** | RJ45 (Industrial Grade) | | **Cable Length** | 2000mm (2.0 Meters) | | **Category Rating** | Cat 5e / Cat 6 (Application dependent) | | **Shielding** | S/FTP or SF/UTP (Double Shielded) | | **Contact Plating** | Gold over Nickel | | **Operating Temp** | -20°C to +80°C | --- ## 2. Part Number Breakdown While manufacturer codes vary slightly, the nomenclature for this specific series generally follows this logic: * **Y-CON**: The product family (Industrial Ethernet). * **C-R402U**: Defines the connector type (RJ45) and the wiring scheme (likely straight-through). * **RJ2L**: Indicates the locking mechanism or the specific strain relief/overmold style. * **2000**: Represents the length in millimeters (2000mm = 2 meters). * **B**: Usually denotes the color (Black) or a specific revision/packaging code. --- ## 3. Key Electronic Features ### A. EMI/RFI Protection The assembly features integrated shielding to prevent electromagnetic interference. In industrial settings where large motors or high-voltage lines are present, this ensures data integrity. ### B. High-Speed Transmission Designed to support **100Base-TX** and **1000Base-T (Gigabit Ethernet)**. The internal twisting of pairs is controlled to minimize crosstalk (NEXT/FEXT). ### C. Industrial Ruggedness Unlike standard office-grade patch leads, this part uses: * **PUR (Polyurethane) or PVC Jacket:** Resistance to oils, chemicals, and abrasion. * **Vibration Resistance:** The locking tabs are reinforced to prevent accidental disconnection in high-vibration environments (like CNC machines or robotic arms). --- ## 4. Typical Applications 1. **Industrial Automation:** Connecting PLCs (Programmable Logic Controllers) to HMIs or sensors. 2. **Machine Vision:** High-speed data transfer for industrial cameras. 3. **Robotics:** Used in cable tracks where flexibility and durability are required. 4. **Outdoor Telecom:** When used with Y-Con IP67 housings, it provides weather-proof data links. ---
