The **F2VS-C2-R/Q** is a specific model within the series of high-precision **Static Sensors (Electrostatic Sensors)** typically manufactured by companies like **Panasonic (formerly SUNX)** or specialized industrial sensor providers. These devices are designed to measure the surface potential (static electricity) of objects on a production line without making physical contact. --- ### 1. Key Technical Specifications The "R/Q" suffix usually denotes specific output configurations or cable types (such as NPN/PNP logic or specific connector types). | Feature | Specification | | :--- | :--- | | **Measurement Type** | Non-contact electrostatic potential | | **Detection Range** | Typically ±20.0 kV (Distance dependent) | | **Operating Voltage** | 12 to 24V DC (±10% ripple) | | **Output Type** | Analog Voltage (e.g., 1-5V) and Digital Control Outputs | | **Response Time** | < 100ms (High speed) | | **Resolution** | Approx. 0.1 kV | --- ### 2. Core Electronic Components The internal architecture of the F2VS-C2-R/Q consists of several sophisticated electronic stages: #### A. The Sensing Head (Vibrating Electrode) Unlike simple voltmeters, these use a **vibrating capacitor** or an **induction electrode**. * **Function:** It converts the static DC field from the target object into an AC signal. This prevents the sensor from becoming "saturated" or biased by its own internal charge. #### B. Signal Conditioning Circuitry * **Preamplifier:** High-impedance FET-input operational amplifiers are used to amplify the tiny induced currents from the sensing head. * **A/D Converter:** Converts the analog voltage into a digital signal for processing by the onboard MCU (Microcontroller). #### C. Microcontroller (MCU) * The "brain" of the unit. It performs distance compensation calculations (since the voltage reading changes based on how far the sensor is from the object) and manages the display. #### D. Output Interface * **Analog Output:** Provides a linear voltage proportional to the detected static charge, allowing integration with PLCs or Data Loggers. * **Digital Outputs (R/Q Logic):** Transistor outputs that trigger alarms if the static charge exceeds a user-defined threshold. --- ### 3. Connection Pinout (General) While you should always consult the specific wiring diagram on the housing, the standard configuration for this series is: ```yaml Brown: +V (12-24V DC) Blue: 0V (GND) Black: Control Output 1 (Static high) White: Analog Output (1-5V DC) Gray: Zero-adjustment input / Reset ``` --- ### 4. Typical Applications 1. **Semiconductor Manufacturing:** Ensuring wafers are not carrying charges that could cause ESD (Electrostatic Discharge) damage. 2. **Film/Plastic Processing:** Monitoring static buildup on rollers to prevent dust attraction or electric shocks to operators. 3. **Labeling/Packaging:** Preventing labels from sticking to machinery due to static.
