The **FVS-54-R** is a specific electronic component often categorized within the field of optical sensors or specialized connector assemblies, frequently associated with **Takex (Takenaka Sensor Group)** or similar industrial automation brands. It is primarily a **Fiber Optic Cable/Sensor head** designed for high-precision detection. --- ### 1. Technical Specifications The "R" suffix typically denotes a "Retro-reflective" or "Right-angle" configuration depending on the specific series, but most commonly, this part belongs to the fiber optic sensor accessory category. | Feature | Specification (Typical) | | :--- | :--- | | **Type** | Fiber Optic Sensor Head | | **Sensing Method** | Reflective / Diffuse Reflective | | **Housing Material** | Stainless Steel or Nickel-plated Brass | | **Fiber Core** | Plastic (PMMA) or Glass (multi-core) | | **Minimum Bending Radius** | R10 to R25 mm | | **Operating Temperature** | -40°C to +70°C | --- ### 2. Key Electronic & Mechanical Components #### A. Fiber Optic Core The internal "wires" are actually optical fibers. The FVS-54-R uses a high-transparency core to transmit light from an amplifier to the sensing point. Because it is non-electrical at the tip, it is immune to **Electromagnetic Interference (EMI)**. #### B. The Sensing Head The "54" designation usually refers to the physical dimensions or the thread size (e.g., M4 or M5 threading). - **Threaded Tip:** Allows for secure mounting in industrial machinery. - **R-Configuration:** Usually indicates a **Right-Angle** beam exit, allowing the sensor to "see" at a 90-degree angle to the cable, which is essential for tight spaces. #### C. Protective Sheathing The electronic signal is protected by a flexible sleeve (often Polyethylene or Stainless steel spiral) to prevent mechanical damage and light leakage. --- ### 3. Application Use Cases Because this part is a passive optical component, it must be paired with an **Electronic Fiber Amplifier** (like the FX or F70 series). 1. **Object Detection:** Counting small parts on a high-speed conveyor. 2. **Positioning:** Detecting the edge of a wafer or circuit board. 3. **Hazardous Environments:** Since there is no electricity at the sensing head, it is safe for use in explosive or wet environments. --- ### 4.
