The **FRTS-HA-R/Q** series refers to a specific line of **Fiber Optic Retro-Reflective Sensors** (often associated with industrial automation brands like Panasonic/Sunx or similar precision sensor manufacturers). These sensors are designed for high-accuracy detection of transparent or opaque objects. Below is a breakdown of the electronic components and technical characteristics of this series. --- ### 1. Core Electronic Components | Component | Function | | :--- | :--- | | **GaAs / AlGaInP LED** | The internal light source that emits a visible red beam or infrared pulse. | | **Photodiode/Transistor** | The receiving element that converts returning light into an electrical signal. | | **ASIC (Integrated Circuit)** | Processes the signal, handles noise suppression, and manages response time. | | **Sensitivity Potentiometer** | An analog or digital adjustment tool used to set the threshold for detection. | | **Fiber Optic Core** | Multicore glass or plastic fibers that transport the light to the sensing head. | --- ### 2. Technical Specifications The "R" and "Q" designations often refer to the lens type or the shape of the sensing head (e.g., Rectangular or Square/Compact). | Feature | Specification (Typical) | | :--- | :--- | | **Sensing Method** | Retro-reflective (Requires a reflector) | | **Light Source** | Red LED (Visible) | | **Operating Voltage** | 12 to 24V DC | | **Output Type** | NPN or PNP (Open Collector) | | **Response Time** | < 1ms | | **Enclosure Rating** | IP67 (Dust and Water resistant) | --- ### 3. Key Electronic Features * **Polarized Filters:** The electronic assembly often includes polarizing filters. This ensures that the sensor only "sees" light reflected back from the specific corner-cube reflector, ignoring reflections from shiny metal objects. * **M8/M12 Connector or Cable:** The electronic interface usually terminates in a 3-wire or 4-wire configuration (Brown: V+, Blue: 0V, Black: Output). * **Operation Indicators:** * **Green LED:** Stability indicator (flashes if the signal is too weak). * **Orange/Red LED:** Operation indicator (lights up when the output is triggered). --- ### 4.
