The **W2PV-C1B1-R2** is a specific model within the industrial switch or signal category, often associated with Omron or similar industrial automation manufacturers. It is a **Pushbutton Switch** component designed for panel mounting in control systems. --- ### Technical Specifications and Breakdown The part number can be broken down into specific electronic and mechanical characteristics: | Feature | Description | | :--- | :--- | | **Component Type** | Illuminated Pushbutton Switch | | **Mounting Diameter** | Typically 16mm or 22mm (Model dependent) | | **Contact Configuration** | Single Pole Single Throw (SPST) or Double Pole (DPDT) | | **Illumination Source** | High-intensity LED | | **Color Code (R2)** | Red (indicates the lens/LED color) | | **Voltage Rating** | Usually rated for 12-24V AC/DC (Logic level) | | **Operation Type** | Momentary (Spring return) | --- ### Key Electronic Components #### 1. The Contact Block This is the heart of the switch. It uses silver or gold-plated contacts to ensure low electrical resistance. In the "C1B1" configuration, it typically refers to a **1NO (Normally Open) + 1NC (Normally Closed)** arrangement, allowing for versatile wiring in safety or signaling circuits. #### 2. LED Illumination Unit The "R2" suffix specifically identifies the **Red LED** module. Internally, this includes: * **Current Limiting Resistor:** Built-in to prevent the LED from burning out when connected to the rated voltage. * **Polarity Protection:** Often includes a diode to protect against accidental reverse wiring. #### 3. Actuator Mechanism The mechanical part that converts physical pressure into electrical connection. It is designed for high durability, often rated for over **100,000 electrical cycles**. --- ### Application Usage These parts are commonly used in: * **Control Panels:** To signal an "Emergency" or "Stop" state. * **PLC Inputs:** Sending a low-voltage signal to a Programmable Logic Controller. * **Human-Machine Interfaces (HMI):** Providing tactile feedback to operators in industrial environments. ---
