The **FLCS-1A-R/K** is a precision linear motion component, typically categorized as a **Linear Position Sensor** or **Linear Potentiometer**. These devices are used to translate mechanical displacement into an electrical signal for control systems. --- ### 1. Key Technical Specifications Based on standard industrial configurations for the FLCS series, the electronic characteristics generally include: | Feature | Specification | | :--- | :--- | | **Output Type** | Analog (Potentiometric) | | **Resistance Tolerance** | ±20% (Standard) | | **Linearity** | ±0.1% to ±1% (depending on specific stroke length) | | **Resolution** | Essentially Infinite (Limited by noise/ADC) | | **Power Rating** | 0.1W to 0.5W (Typical) | | **Operating Temperature** | -30°C to +100°C | --- ### 2. Internal Electronic Components The device consists of three primary electronic elements that work together to provide feedback: 1. **Resistive Element:** A high-precision conductive plastic or cermet track. This acts as a voltage divider. 2. **Wiper (Contact):** A multi-fingered metal contact that moves along the resistive track. Its position determines the output voltage. 3. **Terminal Interface:** * **Terminal 1:** Input Voltage ($V_{in}$) * **Terminal 2:** Output Signal ($V_{out}$) - The wiper signal. * **Terminal 3:** Ground (GND) --- ### 3. Electrical Functionality The FLCS-1A-R/K operates on the principle of a **Voltage Divider**. As the shaft moves, the resistance between the wiper and the ground terminal changes linearly. * **Input:** A stable DC reference voltage. * **Output:** A ratiometric voltage. For example, if the input is 10V and the sensor is at 50% displacement, the output will be 5V. --- ### 4. Common Applications These parts are used in environments where precise position monitoring is required: * **Industrial Automation:** Measuring the stroke of hydraulic or pneumatic cylinders. * **Automotive:** Throttle position or suspension height sensing. * **Robotics:** Joint angle or linear actuator feedback. --- ### 5. Installation Note When integrating the FLCS-1A-R/K into a circuit, it is recommended to use a **High-Impedance Buffer** (like an Op-Amp) or a high-quality Analog-to-Digital Converter (ADC). This prevents "loading" the sensor, which would cause inaccuracies in the linearity.
