The **W5MS-C3-R** is a specific electronic component belonging to the **limit switch** or **micro-switch** category, commonly produced by manufacturers like **OMRON** (or compatible brands). It is primarily used for position detection and safety interlocking in industrial automation. --- ### 1. Technical Specifications The following table outlines the core electronic and mechanical parameters: | Feature | Specification | | :--- | :--- | | **Actuator Type** | Cross-roller plunger | | **Contact Form** | SPDT (Single Pole Double Throw) | | **Electrical Rating** | 10A at 250VAC / 6A at 30VDC | | **Protection Rating** | IP67 (Dust-tight and Water-resistant) | | **Termination** | Pre-wired (Lead wire) | | **Operating Force** | ~11.8 N (Approx. 1.2 kgf) | --- ### 2. Key Electronic Components & Design #### A. Internal Switch Mechanism The heart of the W5MS-C3-R is a **snap-action mechanism**. This ensures that the contacts switch rapidly regardless of the speed at which the physical actuator is pressed, preventing electrical arcing and extending contact life. #### B. Contact Material * **Composition:** Typically Silver Alloy. * **Function:** Designed to handle inductive loads (like motors or solenoids) without welding or excessive carbon buildup. #### C. Wiring Configuration As an SPDT switch, it typically features three wires: 1. **COM (Common):** The input terminal. 2. **NC (Normally Closed):** Connected to COM when the switch is idle. 3. **NO (Normally Open):** Connected to COM when the switch is actuated. --- ### 3. Application Use Cases The "C3" in the model name usually refers to the specific plunger style (Cross-roller), which is ideal for: * **Linear Cams:** Detecting the position of a moving machine part. * **Conveyor Systems:** Counting items or detecting jams. * **Safety Guards:** Ensuring a machine door is closed before operation begins. --- ### 4. Circuit Example Below is a simple representation of how the switch is integrated into a control circuit: ```c // Pseudo-logic for PLC integration IF (LimitSwitch_NO == HIGH) { StopMotor(); // Triggered when actuator is pressed Alarm = ON; } ELSE { RunMotor(); // Standard operating state } ```
