The **FUD-FW5-R/Q** is a high-performance optical sensor component, typically categorized as a **Fiber Optic Cable unit** used in industrial automation. These units are designed to work in conjunction with a fiber optic amplifier (like the Keyence FS series) to detect objects in challenging environments. Below is a breakdown of its electronic and physical characteristics. ### 1. Key Technical Specifications | Parameter | Description | | :--- | :--- | | **Model Type** | Fiber Optic Sensor Head (Tough-Flex) | | **Detection Method** | Through-beam (Requires a transmitter and receiver) | | **Fiber Diameter** | Standard 2.2 mm (Core: Ø 1.0 mm) | | **Minimum Bend Radius** | R5 mm (High flexibility) | | **Ambient Temperature** | -40 to +70 °C | | **Material** | Stainless Steel (Head), Polyethylene (Cable sheath) | --- ### 2. Core Electronic Components & Operation The FUD-FW5-R/Q does not contain active silicon electronics (like microchips) inside the head. Instead, it functions as a **passive optical transmission line**. * **Optical Fiber Core:** High-purity plastic or glass fiber that carries modulated light signals from the amplifier to the sensing point. * **The "R" and "Q" Designations:** * **R (High Flex):** Indicates the use of multi-core fibers which prevent light loss even when the cable is bent sharply. * **Q (Area Detection):** Often signifies a specific lens or array configuration that creates a "screen" or "area" of light rather than a single point, making it ideal for detecting falling objects or inconsistent positions. * **Light Modulation:** While the cable is passive, it is designed to handle high-frequency pulsed light (Red or Infrared) emitted by the amplifier to filter out ambient light interference. --- ### 3. Structural Features The "FW" series is part of the **Tough-Flex** family, which features specific structural enhancements: 1. **Stainless Steel Housing:** The sensing tip is encased in SUS303 or similar metal to protect the fiber end from mechanical impact and chemical exposure. 2. **Hex-Shaped Head:** The "FW" often denotes a flat-bracket or hex-shaped mounting style, allowing for easy installation in tight spaces without additional mounting hardware. 3. **Beam Alignment:** As a through-beam sensor, the "R/Q" variant is optimized for long-range detection (up to several meters depending on the amplifier power). --- ### 4. Application Use-Cases * **Vibratory Feeders:** Detecting small parts moving at high speeds. * **Wafer Detection:** Used in semiconductor manufacturing due to the slim profile. * **Robotic Arms:** The "R" (High Flex) rating allows the cable to be routed through joints that undergo constant motion without the fiber snapping.
