The **Y-CONC-R406M-RJ6P-2000-C** is a specialized industrial cable assembly often utilized in high-precision motion control systems, specifically designed for use with **Yaskawa** AC Servo systems. --- ### 1. Technical Specifications Breakdown The part number follows a specific nomenclature that defines its electronic and physical characteristics: | Parameter | Specification | Description | |:---|:---|:---| | **Cable Type** | Encoder Cable | Transmits feedback signals from motor to drive. | | **Connector A** | 6-Pin Circular | Connects to the motor-side encoder port. | | **Connector B** | RJ45 (or specialized) | Connects to the Servo Drive/Controller. | | **Length** | 2000mm (2 Meters) | Standard short-run connection length. | | **Wiring** | Shielded Twisted Pair | Reduces Electromagnetic Interference (EMI). | | **Application** | Yaskawa Sigma Series | Compatible with R-Series and similar servos. | --- ### 2. Core Electronic Components #### A. Shielded Conductors To maintain signal integrity over high-frequency switching environments, the cable uses **braided copper shielding**. This prevents "noise" from the power cables from corrupting the encoder data (position/velocity). #### B. Twisted Pair Geometry The data lines are twisted to ensure **Differential Signaling** (RS-422/RS-485 standard). This allows the system to cancel out common-mode noise, which is critical for high-resolution 20-bit or 24-bit encoders. #### C. Gold-Plated Contacts The pins within the R406M and RJ6P connectors are typically gold-plated to: * Minimize contact resistance. * Prevent oxidation in industrial environments. * Ensure reliable low-voltage signal transmission. --- ### 3. Usage Context This cable is primarily used to connect a **Yaskawa Sigma-7 or Sigma-5** motor to a controller. It handles the feedback loop that tells the drive exactly where the motor shaft is positioned. #### Electrical Ratings: * **Voltage Rating:** Usually 30V - 50V DC (Signal level). * **Temperature Range:** -20°C to +80°C (Standard industrial grade). * **Bending Radius:** Often designed for "fixed" or "limited flex" installation unless specified as a "High-Flex" variant. ---
