The **F2VS-04W-R** is a specific electronic component typically categorized as a **Board-to-Wire Connector**, often part of the automotive or industrial specialized series manufactured by companies like **JST** (Japan Solderless Terminals) or similar high-reliability connector brands. Below is a detailed breakdown of its electronic and physical characteristics. --- ## 1. Component Overview The F2VS series is designed for compact, high-vibration environments. The "04W" designation typically indicates a **4-position (4-pin)** configuration in a **dual-row** or specific wire-to-board layout. ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Series** | F2VS Series | | **Number of Positions** | 4 Pins | | **Pitch** | Typically 2.0mm or 2.5mm (varies by sub-series) | | **Current Rating** | 1.0A - 3.0A (depending on wire gauge) | | **Voltage Rating** | 100V - 250V AC/DC | | **Operating Temperature** | -40°C to +125°C (Automotive grade) | | **Contact Resistance** | Max 30mΩ | --- ## 2. Key Electronic Features ### A. Mechanical Locking Mechanism The "-R" in the part number often signifies a **Reinforced** or **Side-Lock** mechanism. This ensures that the connector does not decouple under physical stress or high-frequency vibration, which is critical for electronic control units (ECUs) in vehicles. ### B. Contact Material * **Base Material:** Copper alloy for high conductivity. * **Plating:** Usually **Tin-plated** or **Gold-plated** to prevent oxidation and ensure stable signal transmission over the component's lifespan. ### C. Housing Structure * **Material:** High-temperature Thermoplastic (PBT or Nylon). * **Polarization:** The housing is keyed to prevent "mismating" (plugging the connector in backward), which protects the sensitive electronic circuits from reverse polarity damage. --- ## 3. Practical Applications This component is widely used in peripheral electronics where space is limited but reliability is paramount: * **Automotive Electronics:** Airbag sensors, LED lighting modules, and dashboard displays. * **Industrial Automation:** Sensor-to-PCB connections. * **Consumer Robotics:** Internal wiring for motor controllers and logic boards. --- ## 4. Mounting Styles The F2VS-04W-R is generally the **Header** (Male) side of the connection, designed for: 1. **Through-Hole Technology (THT):** Soldered directly through the PCB holes for maximum mechanical strength. 2. **Right-Angle Orientation:** Often indicated by the "W" in Japanese connector nomenclature (Side-entry), allowing the cable to run parallel to the PCB to save vertical space.
