The **F1SP-R100-FT** is a specialized fiber optic sensing component, typically associated with high-precision industrial automation systems (often processed by manufacturers like **Panasonic/Sunx** or similar high-end sensor providers). It is primarily a **Liquid Level Fiber Optic Sensor Head**. --- ## 1. Technical Specifications Below are the key electrical and physical attributes of the F1SP-R100-FT: | Feature | Specification | | :--- | :--- | | **Component Type** | Fiber Optic Sensor Head (Liquid Level) | | **Sensing Method** | Refractive Index / Liquid Contact | | **Fiber Length** | 100cm (Standard 1m) | | **Bending Radius** | R10 mm (High flexibility) | | **Material (Tip)** | Fluorine resin (Teflon) or SUS304 (Varies by sub-model) | | **Ambient Temperature** | -40 to +70°C | --- ## 2. Electronic Operating Principle The F1SP-R100-FT does not contain active electronics (like transistors) within the head itself. Instead, it functions as an **optical waveguide**: 1. **Light Transmission:** Infrared or Red light is emitted from an external amplifier (e.g., FX-100 or FX-500 series). 2. **Refractive Index Detection:** The tip of the fiber uses a prism or a specific cut. * **In Air:** Light reflects off the tip surface and returns to the receiver. * **In Liquid:** Light refracts into the liquid due to the change in refractive index, causing the returning light intensity to drop. 3. **Signal Processing:** The external amplifier detects this drop in intensity and converts it into an electrical output (NPN/PNP). --- ## 3. Key Electronic Advantages * **EMI/RFI Immunity:** Since the sensing head is purely optical (no copper wires at the tip), it is completely immune to electromagnetic interference, making it ideal for high-noise industrial environments. * **Intrinsic Safety:** There is no electrical current at the point of sensing, making it safe for use in explosive or flammable liquid reservoirs (Ex-proof compatibility). * **Corrosion Resistance:** The "FT" designation often refers to a Fluorine-coated (Teflon) tip, allowing the sensor to be submerged in harsh chemicals or acids without short-circuiting. --- ## 4. Typical Connection Setup To use this part, it must be integrated into a larger circuit: 1. **Emitter Fiber Port:** Connects to the light-out port of the amplifier. 2. **Receiver Fiber Port:** Connects to the light-in port of the amplifier. 3. **Amplifier Output:** Typically a 3-wire DC system (Brown: V+, Blue: Ov, Black: Signal). ---
