The **48SV2-RV3DT-T** is a specific model within the series of high-precision **Potentiometer-based Rotary Sensors**, typically manufactured by companies like **Midori Precisions**. These are non-contact or high-durability sensors used to measure angular displacement. --- ### ## Technical Specifications Below are the primary electronic and physical characteristics associated with this specific part number: | Feature | Specification | | :--- | :--- | | **Sensor Type** | Conductive Plastic Potentiometer / Hall Effect | | **Outer Diameter** | 48mm (Standard Large Format) | | **Electrical Travel** | 340° to 360° (Continuous rotation) | | **Output Type** | Analog Voltage / Resistance | | **Resistance Tolerance** | ±15% (Typical) | | **Linearity** | ±0.1% to ±0.5% (High Precision) | | **Operating Temp** | -40°C to +100°C | --- ### ### Component Breakdown 1. **Resistive Element (RV3DT):** The "RV" usually signifies a resistive element made of **Conductive Plastic**. This provides an infinite resolution and a significantly longer life cycle compared to wire-wound types because the friction is minimized. 2. **Housing (48SV2):** The "48" denotes the outer diameter of the sensor body in millimeters. The "S" often refers to a Servo-mount style, which allows for fine rotational adjustment during installation using clamps. 3. **Terminal Configuration (-T):** The suffix "-T" generally indicates **Turret Terminals**. These are robust solder points sticking out of the back or side of the casing, designed for manual wiring in industrial control panels. --- ### ### Applications These parts are commonly found in precision industrial environments: * **Crane Boom Angle:** Monitoring the tilt and rotation of heavy machinery. * **Tension Control:** Measuring the arm position in textile or paper winding machines. * **Robotic Joints:** Providing feedback for the position of a rotating limb. * **Valve Actuators:** Sensing the exact percentage of an industrial valve opening. --- ### ### Circuit Integration Example To read this sensor with a microcontroller (like an Arduino or PLC), use a voltage divider configuration: ```cpp // Basic analog read for a 48SV2 Potentiometer int sensorPin = A0; // Connected to the center wiper terminal int sensorValue = 0; void setup() { Serial.begin(9600); } void loop() { sensorValue = analogRead(sensorPin); // Reads 0-1023 float voltage = sensorValue * (5.0 / 1023.0); Serial.println(voltage); // Output correlates to angle delay(100); } ```
