The **A-KAB-RJ45-4S-1M-R** is a specific industrial-grade interface cable assembly. Below is a breakdown of its electronic and physical components based on standard industrial naming conventions (typically associated with manufacturers like ASSMANN WSW or similar industrial component suppliers). ### Product Specification Overview | Feature | Specification | | :--- | :--- | | **Connector Type A** | RJ45 Male (8P8C) | | **Connector Type B** | RJ45 Male (8P8C) | | **Cable Length** | 1.0 Meter (~3.28 feet) | | **Shielding** | S/FTP or SFTP (Screened Foiled Twisted Pair) | | **Category Rating** | Cat5e or Cat6 (Application dependent) | | **RoHS Compliant** | Yes (Indicated by the "-R" suffix) | --- ### Component Breakdown #### 1. The Connectors (RJ45 4S) The "4S" in the part number typically refers to the shielding and internal wiring configuration: * **Gold Plating:** The contact pins are usually plated with 30μ" to 50μ" of gold to prevent oxidation and ensure low contact resistance over long-term use. * **Shielded Housing:** The RJ45 plugs feature a metal shell (usually nickel-plated brass) to provide a continuous ground path from the cable shield to the device port. #### 2. The Cable Structure * **Twisted Pairs:** 4 pairs of copper conductors. The twisting reduces electromagnetic interference (EMI) and crosstalk between lines. * **Shielding (S):** The "S" signifies an overall braid shield or individual foil shields. This is critical in industrial environments where high-voltage machinery or power lines might cause data corruption. * **AWG (Gauge):** Typically uses 26 AWG or 24 AWG stranded copper wire, balancing flexibility with electrical conductivity. #### 3. Material Properties * **Jacket:** Usually PVC or LSZH (Low Smoke Zero Halogen), depending on the specific environmental rating. * **Molding:** The "boot" at the end of the connector is injection-molded to provide strain relief, preventing the internal copper wires from snapping during repeated bends. ### Typical Applications * **Industrial Ethernet:** Connecting PLC (Programmable Logic Controllers) to HMIs or Switches. * **Server Racks:** Short-distance patching where high-speed data integrity is required. * **Medical Equipment:** Due to the shielded nature, it minimizes RF emissions and susceptibility. ---
