The **KWMS2-FC-R** is a specialized electronic component, typically categorized as a **Micro-Switch** or **Limit Switch**, often utilized in industrial automation, security systems, and high-precision machinery. --- ### 1. General Specifications The KWMS series is known for its compact design and high reliability. Below are the estimated technical parameters based on the standard configuration for this series: | Feature | Specification | | :--- | :--- | | **Component Type** | Micro-Switch / Snap Action Switch | | **Contact Configuration** | Single Pole Double Throw (SPDT) | | **Actuator Type** | Roller Lever (indicated by the "-R") | | **Mounting Style** | PCB Mount or Chassis Mount (depending on pins) | | **Material** | Heat-resistant thermoplastic housing | | **Environmental Rating** | Often rated IP40 or higher (Dust protected) | --- ### 2. Breakdown of the Model Name Electronic part numbers are typically alphanumeric codes where each segment describes a specific physical or electrical attribute: * **KWMS**: The series identifier (usually representing a "Miniature Switch" line). * **2**: Often denotes the physical size or the electrical rating (e.g., 2 Amps or Size Class 2). * **FC**: Represents the terminal type or the casing material (e.g., Fast-Connect or Front-Contact). * **R**: Specifies the **Roller**. This indicates the switch is triggered by a rolling wheel rather than a flat lever or a plunger, reducing friction during actuation. --- ### 3. Electrical Characteristics These parts are designed to handle low to medium power loads. * **Operating Voltage:** Typically 125V AC to 250V AC. * **Current Rating:** Usually between 3A and 10A depending on the specific sub-rating. * **Contact Resistance:** $\leq 50m\Omega$ (initial). * **Insulation Resistance:** $\geq 100M\Omega$ (at 500V DC). --- ### 4. Common Applications Due to the **Roller (-R)** mechanism, this switch is ideal for: 1. **Cam Detection:** Used in motors to detect the position of a rotating cam. 2. **Door/Gate Monitoring:** Detecting when a sliding door has reached its limit. 3. **3D Printers/CNC:** Used as an "End-Stop" sensor to calibrate the X, Y, or Z axis. 4. **Vending Machines:** To track the movement of dispensing mechanisms. ---
