The part number **Y-CONC-R40CU-RJ2L-2000-A** typically refers to a high-performance industrial cable assembly, most commonly associated with **Yaskawa** robotics or motion control systems. Below is a breakdown of the electronic and mechanical characteristics of this component. ### 1. Component Overview This cable is a specialized **Feedback or Encoder Cable** used to connect a servo motor to a drive (servopack). It is designed to transmit high-speed data signals while maintaining signal integrity in electrically noisy environments. --- ### 2. Technical Specifications | Feature | Details | | :--- | :--- | | **Type** | Encoder / Feedback Cable | | **Connector A** | Industrial Rectangular Connector (typically for motor side) | | **Connector B** | RJ45 or specialized 1394-style connector (for drive side) | | **Length** | 2.0 Meters (indicated by the "2000" in the part number) | | **Cable Material** | High-flex Copper (CU), often oil-resistant and flame-retardant | | **Shielding** | Braided Shielding (to prevent Electromagnetic Interference) | --- ### 3. Key Electronic Characteristics #### A. Signal Integrity and Shielding Because this cable carries encoder pulses (feedback), any electromagnetic interference (EMI) can cause positioning errors or "noise" in the motor control system. * **Twisted Pair Wiring:** Internally, wires are twisted to cancel out electromagnetic interference between pairs. * **360° Shielding:** The outer jacket contains a tinned copper braid connected to the connector shells to provide a continuous ground path. #### B. Data Transmission * **Low Capacitance:** The insulation material is chosen to have low dielectric constants, allowing for high-frequency signal transmission without significant attenuation over the 2-meter length. * **Voltage Rating:** Usually rated for low voltage signal levels (typically 5V to 24V DC). #### C. Durability (Mechanical/Electronic Hybrid) * **Flex Life:** These cables are often "High-Flex" rated, meaning the internal copper strands are thinner and more numerous to prevent the wires from breaking due to the repetitive motion of a robotic arm or CNC stage. * **Contact Plating:** The pins are typically gold-plated to ensure low contact resistance and prevent oxidation over time. --- ### 4. Application Usage This specific cable is primarily used in: 1. **Sigma Series Servo Drives:** Linking the feedback port of the drive to the motor's encoder. 2. **Robotic Arms:** Routing through cable tracks where flexibility and signal reliability are critical. 3. **Industrial Automation:** In environments with high VFD (Variable Frequency Drive) noise.
