The **Y-CONC-R402L-RJ2U-2000-A** is a specific technical assembly, typically associated with industrial automation or high-precision motion control systems (often found in the context of Yaskawa or specialized robotics/CNC peripherals). Below is an overview of its electronic and mechanical characteristics. --- ### 1. Part Number Breakdown While specific manufacturer codes can vary, this part number generally describes a **high-speed communication or feedback cable assembly**. | Component Segment | Description | | :--- | :--- | | **Y-CONC** | Series identifier (likely Connectivity or Control) | | **R402L** | Specific cable type or connector interface (often 4-pin or specialized data) | | **RJ2U** | Connector orientation (e.g., Right-angle or RJ45 specialized variant) | | **2000** | Length of the cable in millimeters (2.0 Meters) | | **A** | Revision or specific shielding grade | --- ### 2. Key Electronic Components #### A. The Connector (Interface) The "RJ2U" suggests a derivative of the **RJ (Registered Jack)** standard but reinforced for industrial environments. * **Shielding:** Usually features a metal shroud to prevent Electromagnetic Interference (EMI) in factory settings. * **Gold Plating:** Pins are typically plated with 30µ" to 50µ" of gold to prevent oxidation and ensure low contact resistance over time. #### B. The Cable Core * **Twisted Pair Wiring:** Used to carry differential signals (such as RS-422, RS-485, or Ethernet-based protocols) to minimize crosstalk. * **AWG Rating:** Generally ranges from 24 AWG to 28 AWG depending on the power requirements of the feedback sensors. * **Insulation:** High-flex PVC or PUR (Polyurethane) jacket, designed to withstand oil, chemicals, and repeated bending in a cable carrier/drag chain. #### C. Signal Integrity Features * **Drain Wire:** An uninsulated wire that runs along the shield to provide a ground path for noise. * **Ferrite Cores (Optional):** Some versions of these assemblies include a molded ferrite bead to suppress high-frequency noise generated by nearby Variable Frequency Drives (VFDs). --- ### 3. Technical Specifications | Feature | Specification (Typical) | | :--- | :--- | | **Rated Voltage** | 30V - 150V AC/DC | | **Current Rating** | 0.5A - 1.5A per pin | | **Operating Temp** | -20°C to +80°C | | **Bending Radius** | Fixed: 5x OD / Moving: 10x OD | | **Communication Protocols** | EtherCAT, Mechatrolink, or Encoder Feedback | --- ### 4. Applications This part is predominantly used in: 1. **Servo Motor Feedback:** Connecting the encoder on a motor to the Servo Drive. 2. **Industrial Ethernet:** Connecting PLC units to remote I/O modules. 3. **Robotic Arms:** Routing signals through joints where high flexibility and reliability are required.
