The **FVS-A10-R** is a specific electronic component, typically categorized as a **Fiber Optic Sensor Head** (specifically a diffuse reflective type) often manufactured by brands like **Keyence** or similar automation providers. These parts are critical in industrial automation for detecting the presence, position, or color of objects using light. --- ### 1. Key Technical Specifications The "A10" usually refers to the sensing distance or a specific physical dimension, while "R" often denotes a right-angle or side-view orientation. | Feature | Description | | :--- | :--- | | **Type** | Fiber Optic Sensor Head | | **Detection Method** | Diffuse Reflective (Emitter and Receiver in one head) | | **Fiber Material** | Plastic (typically high-flex or standard) | | **Sensing Direction** | Right-angle / Side-view (R) | | **Ambient Temperature** | -40 to +70 °C (typical industrial range) | | **Minimum Bend Radius** | R10 to R25 (depends on specific fiber core) | --- ### 2. Functional Electronic Design The FVS-A10-R is a "passive" optical component that must be connected to an **Electronic Fiber Amplifier** (such as the FS-N series) to function. #### Internal Composition: * **Emitter Core:** Transmits a modulated light beam (usually Red LED or Infrared) generated by the amplifier. * **Receiver Core:** Captures reflected light from the target object and sends it back to the amplifier's photodiode. * **Optical Fiber:** Bundled plastic or glass strands that guide light via total internal reflection. #### How it works: 1. **Light Source:** The amplifier sends an electrical pulse to an internal LED. 2. **Transmission:** The light travels through the "Emitter" side of the FVS-A10-R. 3. **Reflection:** The light hits a target and bounces back. 4. **Conversion:** The "Receiver" side of the head picks up the reflection; the amplifier converts this light back into an electrical signal and triggers an output (PNP/NPN). --- ### 3. Application Use Cases Because of its small form factor and right-angle design, the FVS-A10-R is used in specific electronic assembly environments: * **Wafer Detection:** Detecting the presence of silicon wafers in thin slots. * **PCB Alignment:** Sensing the edge of a printed circuit board. * **Lead Frame Inspection:** Checking for bent pins on IC chips. * **Tight Spaces:** The "R" (Right-angle) design allows it to be mounted where there is no clearance for a straight sensor head. --- ### 4.
