The **WSP-24A-R** is a high-performance, rotary-type position sensor (potentiometer) typically used in industrial automation, heavy machinery, and control systems. It is designed to convert mechanical angular displacement into a linear electrical signal. --- ## 🛠️ Key Technical Specifications Below are the primary electronic and mechanical characteristics of the WSP-24A-R: | Feature | Specification | | :--- | :--- | | **Sensor Type** | Wire-wound or Conductive Plastic Potentiometer | | **Total Resistance** | Typically 1kΩ, 2kΩ, 5kΩ, or 10kΩ (model specific) | | **Resistance Tolerance** | ±15% | | **Effective Electrical Angle** | 340° (standard) | | **Mechanical Rotation** | 360° (Endless) | | **Independent Linearity** | ±0.5% | | **Power Rating** | 1.0W to 2.0W (at 70°C) | | **Operating Temperature** | -30°C to +85°C | --- ## 🔍 Core Electronic Components The WSP-24A-R operates based on a few critical internal electronic parts: ### 1. Resistive Element This is the "track" that provides the resistance. In the WSP series, this is often a **conductive plastic** track, which offers high resolution and a longer lifespan (millions of cycles) compared to carbon tracks. ### 2. Precious Metal Wiper The wiper is the moving contact that slides across the resistive element. It is usually made from a gold or silver alloy to ensure low contact resistance and minimize electrical noise during rotation. ### 3. Terminals The device features three main terminals: * **Terminal 1 & 3:** Connected to the ends of the resistive element (Input Voltage/Ground). * **Terminal 2:** Connected to the wiper (Output Signal). --- ## 📐 Connection Diagram (Typical) In most control circuits, the WSP-24A-R is wired as a voltage divider: ```mermaid graph LR A[Vcc / Input] --> T1[Terminal 1] T2[Terminal 2 - Wiper] --> B[Output Signal / ADC] T3[Terminal 3] --> C[Ground] ``` --- ## 💡 Common Applications * **Crane Boom Angle:** Sensing the tilt or angle of heavy lifting equipment. * **Valve Positioners:** Monitoring the opening/closing percentage of industrial valves. * **Tension Control:** Used in paper or textile mills to monitor the position of dancer arms. * **Robotics:** Providing feedback for joint rotation or steering angles. ---
