## Overview of the W2PV-C22A-R The **W2PV-C22A-R** is a specific model within the **OMRON W2PV series** of Pushbutton Switches. These are industrial-grade components designed for panel mounting, offering high reliability and tactile feedback for control systems. --- ### 1. Key Technical Specifications Below are the primary electronic and mechanical specifications for this specific part: | Characteristic | Specification | | :--- | :--- | | **Component Type** | Pushbutton Switch (Round) | | **Circuit Configuration** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Actuator Color** | Red (Indicated by the "-R" suffix) | | **Contact Material** | Gold-plated (Optimized for low-current applications) | | **Mounting Hole Diameter** | 22 mm | | **Action Type** | Momentary (Spring return) | | **Illumination** | Non-Illuminated | | **Protection Class** | IP65 (Oil-resistant / Dust-tight) | --- ### 2. Electronic Functionality The W2PV-C22A-R acts as a mechanical bridge in a circuit. Because it is **Normally Open (NO)**, the circuit remains broken until the button is physically depressed. #### Contact Performance * **Gold-Plated Contacts:** Unlike standard silver contacts, gold plating prevents oxidation and ensures high contact reliability. This makes it ideal for PLC (Programmable Logic Controller) inputs and other low-voltage/low-current logic circuits. * **Switching Capacity:** Designed primarily for electronic signals rather than heavy power switching. --- ### 3. Physical Construction The "C22A" designation refers to the physical dimensions and mounting style: 1. **Mounting:** Designed for a standard 22mm diameter cutout, which is the industrial standard for control panels. 2. **Actuator Style:** The button is a round, flush-style actuator. The red color often denotes a "Stop" or "Cancel" function in industrial HMI (Human Machine Interface) design. 3. **Durability:** The unit is built to withstand harsh environments, featuring resistance to common industrial oils and cleaning agents. --- ### 4. Typical Applications * **Logic Inputs:** Sending a "Start" or "Trigger" signal to a PLC. * **Control Panels:** Manual override switches for automated machinery. * **Handheld Pendants:** Used in remote control stations for cranes or industrial arms. ---
