The part number **W2AC-A4CA-R2** typically refers to a specialized AC power cable or power entry module component, often associated with industrial computing, networking hardware, or server rack equipment (frequently used in brands like IEI Integration or similar industrial PC manufacturers). --- ### Technical Specifications Breakdown The alphanumeric code represents specific physical and electrical characteristics. Based on standard industrial nomenclature, here is the breakdown of its electronic parts: | Component Feature | Description | | :--- | :--- | | **Product Type** | AC Power Cable / Power Connector Assembly | | **Voltage Rating** | Typically 125V - 250V AC | | **Current Rating** | Generally rated for 10A to 15A (depending on wire gauge) | | **Connector A** | Standard 3-pin AC Plug (e.g., NEMA 5-15P or Schuko) | | **Connector B** | Industrial-grade 4-pin or Circular Power Connector | | **Cable Length** | Usually 1.8 meters to 2 meters (standard R2 revision) | | **Compliance** | RoHS, UL, or CE certified for industrial environments | --- ### Key Electronic Sub-components 1. **Conductive Core**: High-purity copper wiring, usually 18 AWG or 16 AWG, designed to minimize resistance and heat buildup during continuous operation. 2. **Insulation (Jacket)**: Heavy-duty PVC or SJT-rated shielding. This provides abrasion resistance and protection against electrical leakage in harsh industrial cabinets. 3. **Terminations**: * One end features a molded AC wall plug. * The "A4CA" designation often points to a **4-pin circular aviation-style connector** or a specific locking terminal used to prevent accidental disconnection in high-vibration environments. 4. **Strain Relief**: Reinforced molded plastic at both connection points to prevent internal wire breakage from bending. --- ### Common Applications * **Industrial PCs (IPC):** Powering embedded systems that require a secure, locking power input. * **Medical Equipment:** Reliable power delivery where standard IEC C13 cables might be too loose. * **Automation Controllers:** Providing AC mains power to DIN-rail power supplies or control boxes. ---
