The **W2PV-C22A-R2** is a specific electronic component, typically categorized as a **pushbutton switch** within the industrial automation and control panel sector. It is commonly associated with manufacturers like OMRON or similar industrial part suppliers. --- ### 1. General Specifications This part is designed for high durability and pilot-duty applications. Below are the typical technical characteristics: | Feature | Description | | :--- | :--- | | **Component Type** | Pushbutton Switch (Non-illuminated/Illuminated depending on assembly) | | **Mounting Diameter** | 22 mm (Standard industrial hole size) | | **Operation Type** | Momentary (Spring return) | | **Contact Configuration** | Usually DPST or SPST (often 1NO/1NC) | | **Color** | Red (indicated by the "-R" suffix) | | **IP Rating** | IP65/IP66 (Dust-tight and water-resistant) | --- ### 2. Key Electronic Parts & Construction The assembly consists of several modular sub-components that work together to complete an electrical circuit: 1. **Operator (Actuator):** The visible red button on the front of the panel. It is the mechanical interface for the user. 2. **Contact Block:** The electrical heart of the switch. When the button is pressed, the internal bridge moves to connect or disconnect the terminals. * **Normally Open (NO):** Circuit is open until pressed. * **Normally Closed (NC):** Circuit is closed until pressed (often used for stop functions). 3. **Mounting Collar:** The plastic or metal ring that secures the operator to the panel and provides the interface for snapping on the contact blocks. 4. **Terminals:** Screw-type terminals located at the rear for connecting copper wiring (typically 14-22 AWG). --- ### 3. Application Use Cases This part is frequently found in control circuits rather than power circuits. * **Logic Signaling:** Sending a pulse to a PLC (Programmable Logic Controller) input. * **Motor Starters:** Activating a magnetic contactor to start a motor. * **Manual Overrides:** Allowing an operator to manually trigger a machine cycle. --- ### 4.
