The **F2VS-FWE-R** is a specific model within the **F2VS Series** of electronic components, primarily manufactured by companies like **SMC** or **Fujikura** (depending on the specific industrial application, though most commonly associated with flow sensors or pressure switches). Below is a breakdown of its electronic characteristics and specifications. --- ## 1. Component Overview The F2VS series typically represents a **Digital Flow Switch** or a **Flow Sensor** designed for use with water or specific fluids. The suffix codes denote specific electronic output types and connection methods. ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Model Type** | Digital Flow Switch (Remote Type) | | **Output Method** | NPN or PNP Open Collector (Depending on specific wiring) | | **Power Supply** | 12 to 24 VDC | | **Current Consumption** | $\le$ 50 mA | | **Response Time** | $\le$ 1.5 seconds (Integrated) | | **Protection Class** | IP65 (Waterproof/Dustproof) | --- ## 2. Electronic Parts & Functions ### A. The Sensor Unit (FWE) The "FWE" designation usually refers to the **Flow Element** or the wet part of the sensor. * **Impeller/Karman Vortex:** Uses a mechanical or sonic element to detect flow speed. * **Transducer:** Converts the mechanical movement or pressure differential into a low-voltage electrical signal. ### B. Output Characteristics (-R) The **-R** suffix is critical for electronic integration. It typically signifies a **Remote Type** or a specific **Connector Lead**: * **Switching Output:** Provides a digital signal (High/Low) when flow reaches a predefined set point. * **Analog Output (Optional):** Some variations provide a 1-5V or 4-20mA signal proportional to the flow rate for PLC monitoring. --- ## 3. Wiring Configuration For the electronic integration of the F2VS-FWE-R, the following wiring logic is standard: ```yaml Wiring Guide: Brown: DC (+) 12-24V Power Supply Blue: DC (-) 0V / Common Black: OUT1 (Main Switch Output) White: OUT2 (Sub-Switch or Analog Output) ``` --- ## 4. Key Electronic Features * **Hysteresis Mode:** Prevents "chattering" (rapid switching) when the flow rate fluctuates near the set point. * **Integrated Display:** Most models feature a 2-color LED display (Red/Green) to indicate the output status and numerical flow value. * **Reverse Polarity Protection:** Protects the internal circuitry if the DC power leads are accidentally swapped. ---
