The **FUD-16-R.SLASHQ** (often referenced as FUD-16-R/Q) is a high-performance **Fiber Optic Sensor Amplifier** manufactured by **TAKEX** (Takenaka Sensor Group). It is designed for precision industrial automation, utilizing fiber optic cables to detect small or fast-moving objects in environments where standard sensors cannot fit. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Output Type** | NPN / PNP (Depending on specific wiring configuration) | | **Response Time** | Ultra-high speed (approx. 20μs to 500μs depending on mode) | | **Display** | Dual Digital Display (Threshold and Current Value) | | **Supply Voltage** | 12 - 24V DC | | **Light Source** | Red LED (Visible) | | **Sensitivity Adjustment** | Teaching (Auto/Manual/Full Auto) | --- ### 2. Core Electronic Components & Features #### A. Dual Digital Display The device features two distinct 4-digit LED displays. - **Green Display:** Shows the set threshold (the value at which the sensor triggers). - **Red Display:** Shows the real-time intensity of the received light. #### B. Internal Circuitry (ASIC) The "SLASHQ" variant utilizes an advanced ASIC (Application-Specific Integrated Circuit) that allows for: * **High Resolution:** Capable of detecting minute changes in light intensity. * **Mutual Interference Prevention:** Allows multiple sensors to be mounted side-by-side without optical cross-talk. #### C. Output Protection The electronic output stage is equipped with: * **Short-circuit protection:** Prevents damage if the output wires are crossed. * **Reverse polarity protection:** Safeguards the unit if the power supply leads are swapped. --- ### 3. Connection and Wiring The sensor typically uses a standard 4-wire configuration: ```yaml Brown: +V (12-24V DC) Blue: 0V (GND) Black: Control Output (Load) White: External Input (Remote Teaching or Bank selection) ``` --- ### 4. Operational Modes The electronic logic of the FUD-16-R series allows for several "Teaching" modes: 1. **Full Auto Teaching:** Calibrates sensitivity while the production line is moving. 2. **Two-point Teaching:** Calibrates based on the presence and absence of a target. 3. **Positioning Teaching:** Specifically for high-accuracy edge detection.
