The **F2TS-N3-R/Q** is a specific model within a series of industrial sensors, typically categorized as a **Fiber Optic Amplifier** or a **Photoelectric Sensor**. These devices are used in automation to detect the presence, absence, or distance of objects using light transmitted through fiber optic cables. --- ## 1. Technical Specifications Below are the primary electronic and operational characteristics for this component: | Feature | Specification | | :--- | :--- | | **Sensor Type** | Fiber Optic Amplifier | | **Output Type** | NPN / PNP (Model dependent, typically Open Collector) | | **Control Output** | Max 100mA (Short-circuit protected) | | **Supply Voltage** | 12 - 24V DC (±10% ripple) | | **Response Time** | High-speed (Standard < 500μs, Fine mode varies) | | **Light Source** | Red LED (typically 660nm) | | **Display** | Dual Digital Display (Threshold and Current Value) | | **Connection** | M8 Connector (Q suffix) or Pre-wired (R suffix) | --- ## 2. Key Electronic Components & Functions ### A. The Optical Engine (Transceiver) * **Emitter:** A high-intensity Red LED that pulses light into the fiber optic cable. * **Receiver:** A photodiode or phototransistor that converts returning light into an electrical signal. ### B. Signal Processing (ASIC) The "brain" of the F2TS-N3 involves an Application Specific Integrated Circuit (ASIC) that performs: 1. **Threshold Comparison:** Compares the intensity of received light against a user-defined set point. 2. **Hysteresis Control:** Prevents "chattering" (rapid switching) when an object is at the edge of the sensing range. 3. **Mutual Interference Prevention:** Allows multiple sensors to be mounted side-by-side without their light beams interfering with one another. ### C. Output Circuitry The device uses a **Transistor Output**. * **NPN:** Switches the Load to the negative (0V) rail. * **PNP:** Switches the Load to the positive (24V) rail. * **Protection:** Includes reverse polarity protection and overcurrent protection to prevent damage from wiring errors. --- ## 3. Suffix Breakdown (R/Q) The suffix in the part number indicates the electrical connection style: * **-R:** Refers to a **Robot Cable** or highly flexible cable. It is pre-wired (usually 2 meters) and designed for applications where the sensor head moves frequently. * **-Q:** Refers to an **M8 Quick-Disconnect Connector**. This allows for easy replacement without re-routing long cable runs. --- ## 4.
