The **F2TS-2D-R/Q** is a high-performance, dual-channel photoelectric safety sensor (often categorized under safety light curtains or multi-beam sensors) typically manufactured by brands like **Panasonic (formerly SUNX)** or specialized safety component OEMs. It is designed for perimeter guarding and point-of-operation protection in industrial automation. --- ### ## Technical Specifications Overview The following table summarizes the primary electronic and physical characteristics: | Feature | Specification | | :--- | :--- | | **Type** | Dual-beam Safety Photoelectric Sensor | | **Operating Voltage** | 24V DC (±10%) | | **Output Type** | PNP or NPN (Model dependent, typically "R" signifies Relay/PNP) | | **Sensing Range** | 0.2m to 5m (Standard) / Up to 10m (Long range) | | **Response Time** | < 20ms | | **Protection Rating** | IP67 (Dust-tight and Water-resistant) | | **Connection** | M12 Connector or Hard-wired cable | --- ### ### Key Electronic Components & Functionality #### 1. Infrared Emitter and Receiver The system consists of two separate units: * **Emitter (T):** Contains Gallium Arsenide (GaAs) infrared LEDs that pulse at a specific frequency to avoid interference from ambient shop light. * **Receiver (R):** Contains phototransistors tuned to the emitter's frequency. It processes the light signal and converts it into an electrical status. #### 2. Control Logic (The "Q" suffix) The "Q" in the part number often refers to the **Quick-connect** or specific **Control Logic** integration. * **Self-Diagnosis:** The internal circuitry performs a continuous "Self-Check." If an internal component (like a transistor) fails, the device automatically enters a "Safe State" (OFF). * **Dual-Channel Redundancy:** It uses two independent outputs. If one circuit fails, the other ensures the machine still stops. #### 3. Output Circuits The device typically utilizes **OSSD (Output Signal Switching Device)** outputs. * These outputs are monitored for short circuits to the power supply or between the two outputs. * The "R" variant often indicates a specific **Control Relay** compatibility, allowing it to interface directly with safety relays or safety PLCs. --- ### ### Wiring Configuration (Typical) Standard M12 5-pin or 8-pin wiring is common for this series: ```yaml Pin 1: Brown (+24V DC) Pin 2: White (Output 2 / Diagnostic) Pin 3: Blue (0V / GND) Pin 4: Black (Output 1 / Control) Pin 5: Gray (Test / Reset Input) ``` --- ### ### Common Applications * **Robotic Cells:** Ensuring the robot stops if a human enters the workspace. * **Palletizers:** Detecting body entry into hazardous areas. * **Power Presses:** Providing point-of-operation guarding to prevent finger/hand injuries.
