Based on your query, the **WS10-100-R1K** is a high-precision **Draw-Wire Potentiometer** (also known as a string pot or cable-extension transducer). It is used to convert linear motion into an electrical resistance signal. --- ### 1. General Specifications This sensor belongs to the "WS10" series, which is characterized by its compact size and industrial durability. | Feature | Specification | | :--- | :--- | | **Full Stroke Length** | 100 mm | | **Output Type** | Potentiometric (Resistance) | | **Nominal Resistance** | 1 kΩ (1,000 Ohms) | | **Linearity** | ±0.1% to ±0.05% (standard/precision) | | **Repeatability** | ±0.02 mm | | **Housing Material** | Anodized Aluminum / Plastic | | **Cable Material** | Stainless Steel (coated) | --- ### 2. Breakdown of the Model Code The part number follows a specific nomenclature that defines its electronic and mechanical behavior: * **WS10**: The series/model family (compact housing design). * **100**: The measurement range in millimeters (0 to 100 mm). * **R1K**: The electrical output. "R" stands for Resistance, and "1K" indicates a total resistance of 1,000 Ohms. --- ### 3. Electronic Operation The device functions as a **Voltage Divider**. Internally, it consists of a high-precision hybrid potentiometer coupled to a spring-loaded drum. 1. **Input**: A supply voltage ($V_{in}$) is applied across the two ends of the internal resistor. 2. **Mechanism**: As the wire is pulled out, the drum rotates, moving the potentiometer wiper. 3. **Output**: The voltage measured at the wiper ($V_{out}$) changes linearly in proportion to the extension of the wire. #### Wiring Diagram (Typical) ```text Pin 1: Input Voltage (+) Pin 2: Signal Output (Wiper) Pin 3: Ground (-) ``` --- ### 4. Key Advantages and Use Cases * **Simplicity**: Does not require complex signal conditioning; can be read directly by an Analog-to-Digital Converter (ADC). * **Compactness**: Ideal for tight spaces where traditional rod-type LVDTs or linear scales won't fit. * **Applications**: * Hydraulic cylinder position monitoring. * Testing machines (material displacement). * Medical equipment (table height/positioning). * Industrial automation and robotics.
