The **48SV-1RVG-R** is a specific part number typically associated with **rotary sensors** or **potentiometers**, often manufactured by companies like Noble or similar electronic component vendors. These are widely used in automotive HVAC systems, industrial controls, and consumer electronics for position sensing. --- ### 1. Technical Specifications The following table outlines the typical electrical and mechanical characteristics for this class of component: | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Rotary Position Sensor / Potentiometer | | **Resistance Value** | Variable (often 10kΩ or 5kΩ depending on sub-series) | | **Rotation Angle** | 360° Continuous (Effective angle varies) | | **Operating Voltage** | 5V DC (Standard for sensors) | | **Tolerance** | ±20% | | **Operating Temperature** | -40°C to +85°C | | **Mounting Type** | Surface Mount (SMD) or Through-Hole | --- ### 2. Key Internal Components The 48SV series generally consists of three main electronic/mechanical parts: 1. **Resistive Element:** A carbon or conductive plastic track that provides the resistance. 2. **Wiper (Contact):** A metal brush that moves along the resistive track to change the output voltage based on position. 3. **Housing:** Heat-resistant plastic designed to withstand automotive environments. --- ### 3. Pin Configuration and Circuitry Most sensors in this category utilize a 3-pin configuration to act as a **Voltage Divider**: * **Pin 1 (Input):** Connected to the supply voltage (VCC). * **Pin 2 (Output/Wiper):** Provides the analog signal proportional to the rotation angle. * **Pin 3 (Ground):** Connected to the circuit ground (GND). ```cpp // Example: Reading the sensor value on an Arduino int sensorPin = A0; // Output from Pin 2 of 48SV-1RVG-R int val = 0; void setup() { Serial.begin(9600); } void loop() { val = analogRead(sensorPin); // Reads 0 to 1023 Serial.println(val); delay(100); } ``` --- ### 4. Common Applications * **Automotive:** Air conditioning damper motor position sensing (detecting if vents are open or closed). * **Robotics:** Detecting the angle of joints or actuators. * **Industrial:** Valve position feedback and control panel knobs. ---
