The **LCS-25-R** refers to a specific series of miniature, high-precision linear cable sensors (often called string potentiometers or draw-wire sensors). These components are designed to convert linear motion into an electrical signal using a retractable cable mechanism. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. Technical Specifications The "25" in the model name typically denotes the measurement range (usually 2.5 inches or 25 inches depending on the specific manufacturer's catalog), and the "R" often refers to a specific connector or mounting orientation. | Feature | Specification Details | | :--- | :--- | | **Sensor Type** | Precision Conductive Plastic Potentiometer | | **Output Signal** | Voltage Divider (Analog) | | **Input Voltage** | Up to 30V DC (Standard 5V or 10V recommended) | | **Resistance** | 5K or 10K Ohms (Typical) | | **Linearity** | ±0.25% to ±1.0% of Full Scale | | **Resolution** | Essentially Infinite (Analog) | | **Cable Material** | Stainless Steel (Nylon Coated) | --- ### 2. Internal Electronic Components The device operates on a simple but effective electromechanical principle: * **The Potentiometer:** The heart of the unit is a multi-turn or high-precision rotary potentiometer. It uses a conductive plastic element which offers a long life cycle and low noise. * **The Spring Motor:** A constant-force power spring ensures that the cable remains taut and retracts consistently. * **The Spool:** As the cable is pulled out, it rotates a spool coupled to the potentiometer shaft, changing the resistance value proportional to the distance. --- ### 3. Wiring and Connectivity Most LCS-25-R sensors utilize a 3-wire configuration. ```c // Standard 3-Wire Potentiometric Connection Pin 1: Input Voltage (VCC) Pin 2: Output Signal (Wiper) Pin 3: Ground (GND) ``` **Application Tip:** When connecting this to a microcontroller (like an Arduino or PLC), ensure you use an Analog-to-Digital Converter (ADC) pin to read the varying voltage from Pin 2. --- ### 4. Key Advantages 1. **Compact Form Factor:** Designed for space-constrained environments. 2. **Ease of Integration:** Since it acts as a simple variable resistor, no complex communication protocols (like I2C or SPI) are required. 3. **Durability:** The "R" series often features ruggedized housings for industrial or flight-test applications. ---
