The **F2VS-5WD-R** is a specific electronic component typically categorized as a **Vibration Sensor** (often used in security, automotive, or industrial machinery monitoring). Below is a detailed breakdown of its electronic characteristics and specifications. --- ## 1. Core Technical Specifications The F2VS series is designed to detect physical movement or mechanical shock. | Feature | Specification | | :--- | :--- | | **Component Type** | Vibration / Shock Sensor | | **Model Code** | F2VS-5WD-R | | **Mounting Type** | Through-hole or Lead wire (depending on housing) | | **Detection Principle** | Mechanical/Spring-contact or Piezoelectric | | **Directionality** | Omni-directional (detects vibration from multiple axes) | | **Operating Voltage** | Low voltage (typically < 24V DC) | | **Contact Resistance** | Low (initial state) | --- ## 2. Pinout and Internal Electronics While internal designs vary slightly by manufacturer, the "5WD" variant generally follows this logic: * **Switch Mechanism:** It acts as a "Normally Closed" (NC) or "Normally Open" (NO) switch. When a vibration exceeds a specific G-force threshold, the internal contact vibrates, momentarily breaking or making the circuit. * **Sensitivity:** The "5" in the model name often refers to a specific sensitivity rating or a 5V logic compatibility. * **Termination:** The "-R" suffix usually denotes "RoHS Compliant" or a specific Lead-free coating on the terminals. --- ## 3. Key Electronic Characteristics ### A. Sensitivity Threshold This part is tuned to ignore minor environmental noise (like a nearby fan) but trigger when a specific impact occurs. This is achieved through the tension of an internal spring or the mass of a suspended element. ### B. Signal Output The output is typically a **digital pulse**. In a microprocessor circuit (like Arduino or ESP32), you would treat this as a digital input. * **Resting State:** High (if using a pull-up resistor). * **Trigger State:** Low (when vibration disrupts the contact). ### C. Typical Circuit Integration To use the F2VS-5WD-R effectively, the following components are usually added: 1. **Pull-up Resistor (10kΩ):** To ensure a stable logic signal. 2. **Debouncing Capacitor:** Because the mechanical contact "bounces" during a vibration event, a small capacitor (0.1µF) is often used to smooth the signal. --- ## 4. Common Applications * **Anti-Theft Devices:** Detecting if a window is broken or a vehicle is moved. * **Industrial Maintenance:** Monitoring motors for excessive shaking that indicates bearing failure. * **Consumer Electronics:** "Wake-up" functions (device turns on when picked up). ---
