The part number **48AV-2RV6-R** refers to a specific series of **Rotary Potentiometers** or **Encoders**, typically manufactured by companies like **Bourns** or similar industrial component brands. Based on standard electronic nomenclature for this series, here is the technical breakdown: ### 1. Component Overview This component is an electromechanical device used to adjust electrical signals or sense mechanical rotation. | Feature | Specification | | :--- | :--- | | **Component Type** | Rotary Potentiometer / Control | | **Mounting Type** | Through-hole (PCB Mount) | | **Adjustment Type** | Top Adjust | | **Termination** | Radial Pins | | **Material** | Cermet or Carbon Composition | --- ### 2. Part Number Breakdown While manufacturer codes vary slightly, the "48AV" series generally follows this logic: * **48**: Represents the series size (often 9mm or 12mm square body). * **AV**: Indicates the mechanical configuration (Horizontal/Vertical mount with specific pin spacing). * **2RV**: Often denotes a specific taper (Linear or Audio) and a high-rotation life cycle. * **6**: Usually refers to the shaft length or the resistance value code. * **R**: Indicates compliance with **RoHS** (Reduction of Hazardous Substances) standards. --- ### 3. Key Technical Characteristics ### A. Mechanical Specifications * **Rotational Life**: Often rated for 10,000 to 50,000 cycles. * **Shaft Style**: Typically a "D-type" or "Flatted" shaft to prevent knob slippage. * **Detents**: May feature center-clicks or multiple detents for tactile feedback. ### B. Electrical Specifications * **Resistance Range**: Commonly available from $1k\Omega$ to $500k\Omega$. * **Tolerance**: Usually $\pm10\%$ or $\pm20\%$. * **Power Rating**: Low power, typically $0.05W$ to $0.1W$ (suitable for signal processing, not power regulation). --- ### 4. Typical Applications These parts are widely used in the following sectors: 1. **Consumer Electronics**: Volume controls, tone adjustment in amplifiers, and radio tuning. 2. **Industrial Controls**: Speed settings on motor controllers or timers. 3. **Medical Equipment**: Calibration points on diagnostic interfaces. 4. **Pro-Audio**: Mixing consoles and guitar pedal effects. ---
