The part number **48SV2-RV5WDRR** typically refers to a specific configuration of an industrial-grade **Rotary Position Sensor** or an **Encoder**, often used in automotive, heavy machinery, or aerospace applications (commonly associated with brands like Piher or similar high-precision sensor manufacturers). Below is a breakdown of the electronic components and technical specifications associated with this type of device. --- ### 1. Technical Specifications Overview This part is a Hall-effect based non-contact rotary position sensor designed for harsh environments. | Parameter | Specification | | :--- | :--- | | **Technology** | Hall-Effect (Non-contact) | | **Supply Voltage (Vcc)** | 5V DC ± 10% | | **Output Type** | Ratiometric Analog (0.5V to 4.5V typical) | | **Rotational Life** | Up to 50,000,000 cycles | | **Operating Temperature** | -40°C to +125°C | | **Ingress Protection** | IP67 / IP69K (Dust and Waterproof) | | **Active Electrical Angle** | Customizable (often 360° or specific sectors) | --- ### 2. Key Electronic Components & Internal Architecture #### A. Hall-Effect IC The core of the part is a **programmable magnetic Hall-effect sensor IC**. Unlike traditional potentiometers that use a physical wiper, this uses a magnetic field to detect the angle of the shaft. * **Advantage:** No mechanical wear, leading to extreme longevity. * **Signal Processing:** The IC includes an integrated DSP (Digital Signal Processor) to linearize the output. #### B. Redundancy (WDRR Suffix) The "WDRR" or "RR" notation often signifies **Redundant Outputs**. * **Dual Circuits:** The device contains two independent sensor elements. * **Safety:** If one circuit fails, the other continues to provide position data. This is critical for "Drive-by-Wire" or "Steer-by-Wire" systems where failure could be catastrophic. #### C. Interface & Output The sensor converts the magnetic flux density into a voltage signal: * **RV5:** Indicates a **Ratiometric 5V** output. The output voltage is a percentage of the input supply voltage. * **Protection Circuitry:** Includes internal TVS diodes for ESD protection and capacitors for EMI/RFI filtering. --- ### 3. Connection Pinout (Typical) While specific to the connector housing, the internal electronic wiring usually follows this logic: | Pin Number | Function | Description | | :--- | :--- | :--- | | 1 | VCC | 5V Power Supply | | 2 | GND | Ground | | 3 | OUT 1 | Primary Analog Output | | 4 | OUT 2 | Secondary (Redundant) Output | --- ### 4. Typical Applications * **Throttle Position Sensors (TPS):** Measuring the pedal or butterfly valve angle. * **Suspension Height Sensors:** Detecting chassis movement in heavy vehicles. * **Steering Angle:** Feedback for electronic power steering systems. * **Valves & Actuators:** Monitoring the precise position of industrial flow controls.
