The **FT-R60Y** is a high-performance **Fiber Optic Sensor Unit** manufactured by Keyence. It belongs to the "Tough Fiber" series, designed for industrial automation and precise object detection. --- ### 1. Key Technical Specifications The FT-R60Y is a **Thrubeat (Through-beam)** type sensor, meaning it consists of a separate transmitter and receiver. | Feature | Specification | | :--- | :--- | | **Model Type** | Thrubeat (Through-beam) | | **Fiber Diameter** | Ø 2.2 mm | | **Fiber Length** | 2 meters (Free-cut) | | **Minimum Bend Radius** | R1 mm (High-flexibility) | | **Operating Temperature** | -40 to +70 °C | | **Enclosure Rating** | IP67 (Water/Dust resistant) | --- ### 2. Electronic & Structural Components #### A. Optical Fiber Core The "electronic" functionality of this part is actually based on **Optoelectronics**. The core is made of high-quality plastic or glass fibers that transmit light pulses from a main amplifier unit (such as the Keyence FS-N series). * **Small Beam Spot:** Designed for detecting very small targets or operating in tight spaces. * **Sensing Head:** The tip is encased in a stainless steel housing to protect the fiber termination. #### B. The "Tough Fiber" Technology Unlike standard fibers that break when bent, the FT-R60Y uses a multi-core or specialized cladding structure. * **Flexibility:** Allows for a bend radius of 1mm without losing signal intensity. * **Durability:** Resists repeated mechanical stress in moving parts (like robotic arms). #### C. Connector Interface The ends of the fibers are "free-cut," meaning they are inserted into a fiber optic amplifier. * **Transmitter Side:** Converts electrical signals into light (usually LED). * **Receiver Side:** Captures the light and converts it back into an electrical signal (Phototransistor/Photodiode) inside the amplifier base. --- ### 3. Application Use Cases * **Small Part Detection:** Identifying tiny components on a conveyor. * **Positioning:** Ensuring a robotic arm has reached a specific XYZ coordinate. * **Harsh Environments:** Since the "head" (FT-R60Y) has no active electrical circuits (only light), it is immune to Electrical Magnetic Interference (EMI). ---
