The **48SV2-RV6SRR** is a specific model identifier typically associated with **Nidec Copal Electronics** (or sometimes linked to industrial automotive/sensor components). This part belongs to the **SV2 series**, which consists of high-precision, contactless magnetic rotary sensors. --- ### 1. Key Technical Specifications Based on the standard nomenclature for this series, here are the primary specifications: | Feature | Specification | | :--- | :--- | | **Part Series** | SV2 Series (Contactless Rotary Sensor) | | **Technology** | Hall Effect (Magnetic) | | **Supply Voltage** | 5V DC ± 0.5V | | **Rotational Angle** | Usually 360° (Continuous) or specific effective angles | | **Output Type** | Ratio-metric Analog (often 10% to 90% of Vcc) | | **Linearity** | ±1% to ±2% (Full Scale) | | **Service Life** | > 50 million cycles (due to contactless design) | --- ### 2. Breakdown of Part Number Nomenclature While exact manufacturer datasheets can vary slightly by region, the code generally breaks down as follows: * **48**: Refers to the outer diameter of the housing (approx. 48mm). * **SV2**: The product family (Super-mini Vertical/Rotary series). * **RV6**: Often indicates the specific output characteristics or the internal IC configuration (e.g., Redundant Dual Output). * **SRR**: Typically denotes the mounting style, shaft shape, or environmental sealing rating (IP rating). --- ### 3. Core Components and Operation The internal "parts" of this electronic component include: 1. **Permanent Magnet**: Mounted on the rotating shaft. 2. **Hall Effect IC**: A specialized semiconductor that detects the change in the magnetic field as the shaft turns. 3. **Signal Processing Circuit**: Converts the raw magnetic flux data into a linear voltage output. 4. **Housing**: Usually made of high-grade plastic or aluminum with ball bearings to ensure smooth rotation. --- ### 4. Advantages & Applications Because this is a **contactless** sensor, it does not suffer from the mechanical wear found in traditional potentiometers (which use a "wiper" on a resistive track). #### Common Applications: * **Electronic Throttle Control**: Measuring pedal or valve positions. * **Industrial Robots**: Determining joint angles. * **Medical Equipment**: Precise positioning of moving limbs or beds. * **Agricultural Machinery**: Steering angle detection. --- ### 5. Wiring Diagram (General) Standard analog versions typically utilize a 3-pin or 6-pin (for redundancy) configuration: ```text Pin 1: Vcc (+5V) Pin 2: Output (0.5V - 4.5V) Pin 3: Ground (GND) ```
