The **VOS2T-R-3104** is a specialized precision potentiometer, typically categorized as a **Single-Turn Wirewound Precision Potentiometer**. These components are designed for industrial applications requiring high reliability, durability, and accurate linear positioning. --- ### 1. Key Technical Specifications Based on the standard nomenclature for the VOS series, here are the primary electronic characteristics: | Parameter | Specification (Typical) | | :--- | :--- | | **Resistance Value** | 10k $\Omega$ (indicated by the '104' code) | | **Resistance Tolerance** | $\pm 5\%$ to $\pm 10\%$ | | **Linearity** | $\pm 0.5\%$ to $\pm 1.0\%$ | | **Power Rating** | 1.0W to 2.0W at 70°C | | **Electrical Travel** | 340° $\pm 5°$ | | **Mechanical Travel** | 360° (Continuous rotation) | | **Temperature Range** | -55°C to +125°C | --- ### 2. Breakdown of the Part Number The alphanumeric code provides specific details about the construction of the unit: * **VOS2T**: Refers to the series type (Standard precision wirewound) and physical frame size (often size 20 or similar diameter). * **R**: Generally signifies the mounting style (e.g., Rear-mount or specific shaft configuration). * **3104**: * **3**: Manufacturing/Series revision or specific mechanical feature. * **104**: The resistance code. $10 \times 10^4 = 100,000$ Ohms ($100k \Omega$), or in some specific legacy formats, it translates directly to $10k \Omega$ depending on the manufacturer's base multiplier. --- ### 3. Internal Components & Materials * **Wirewound Element**: The resistance track consists of a precision-drawn alloy wire wound tightly around a non-conductive ceramic or plastic mandrel. This provides excellent thermal stability. * **Wiper Assembly**: Usually made of precious metal alloys (such as Gold or Palladium) to ensure low contact resistance and minimize electrical noise during adjustment. * **Housing**: Typically an aluminum or high-grade plastic shell designed to shield the internal elements from EMI (Electromagnetic Interference). * **Bearings**: High-quality stainless steel ball bearings are often used to ensure smooth rotation and a long rotational life (often exceeding 1 million cycles). --- ### 4. Common Applications Due to its high precision and rugged nature, the VOS2T-R-3104 is commonly found in: 1. **Industrial Controls**: Used as a feedback sensor for valve positioning. 2. **Medical Equipment**: Fine-tuning settings in diagnostic machinery. 3. **Avionics**: Flight control surface monitoring. 4. **Robotics**: Joint angle sensing and positioning.
