The **48SV2-RV0SRR** appears to be a specific model or sub-component within the category of **High-Precision Potentiometers** or **Rotary Sensors**, often associated with industrial automation and precision control systems (frequently manufactured by brands like Sakae or similar precision component specialists). Below is a breakdown of the electronic and mechanical characteristics typical of this part series. --- ### 1. Component Overview The 48SV series is generally a **Multi-turn Helical Potentiometer** or a high-durability rotary sensor. These are used to translate mechanical rotation into a precise electrical signal (resistance change). | Feature | Specification Details | | :--- | :--- | | **Type** | Precision Wirewound or Hybrid Potentiometer | | **Turns** | Typically 10-turn (though "SV" can denote variations) | | **Resistance Tolerance** | ±5% to ±1% (Precision grade) | | **Linearity** | ±0.25% to ±0.1% (Independent linearity) | | **Power Rating** | Approximately 2.0W at 40°C | ### 2. Technical Breakdown * **Rotary Life:** Designed for long life cycle (often 1 to 5 million shaft revolutions). * **Housing:** Usually constructed with a rugged metal or high-impact plastic casing for industrial environments. * **Terminals:** Gold-plated or silver-plated terminals to prevent oxidation and ensure stable electrical contact. * **Shaft Style:** The "RV" in the suffix often indicates a specific shaft configuration (e.g., slotted, round, or flatted) and "0SRR" likely defines the specific electrical travel and resistance taper. ### 3. Pinout & Connection Most high-precision potentiometers follow a standard 3-terminal configuration: | Terminal No. | Function | Description | | :--- | :--- | :--- | | **1** | CW/CCW End | Fixed end of the resistor element | | **2** | Wiper | The moving contact providing variable voltage/resistance | | **3** | CW/CCW End | Opposite fixed end of the resistor element | ### 4. Common Applications Due to its precision, this part is found in: 1. **Servo Systems:** Used as feedback sensors to determine the exact position of a motor shaft. 2. **Medical Equipment:** For fine-tuning control interfaces on imaging or surgical devices. 3. **Industrial Joysticks:** Providing high-resolution input for heavy machinery. 4. **Calibration Tools:** Used in laboratory instruments where high-resolution resistance adjustment is required. ---
