The **W2PV-C22B-R** is a specific part number belonging to a series of industrial push-button switches, typically manufactured by companies like **IDEC** or similar industrial control component providers. Based on the nomenclature, this part is part of a **22mm diameter mounting** pilot device family. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. Component Specifications The following table outlines the technical parameters of the W2PV series: | Parameter | Specification | | :--- | :--- | | **Mounting Hole Size** | 22mm (Standard Industrial) | | **Component Type** | Illuminated Push Button / Pilot Device | | **Color** | Red (Indicated by the "R" suffix) | | **Illumination Source** | LED | | **Input Voltage** | Typically 24V AC/DC (standard for this series) | | **Contact Configuration** | Usually 1NO (Normally Open) or 1NC (Normally Closed) | | **Degree of Protection** | IP65 / NEMA 4X (Water/Dust resistant) | --- ### 2. Part Number Breakdown Industrial switches use "Smart Part Numbers" where each character defines a feature: 1. **W2P:** Refers to the series family (22mm Miniature Control Units). 2. **V:** Indicates the operator style (often "Flush" or "Extended" lens). 3. **C:** Refers to the contact block type or housing material. 4. **22:** Represents the physical mounting diameter (22mm). 5. **B:** Often denotes the voltage code (e.g., 24V) or terminal style. 6. **R:** The color of the lens/button (**Red**). --- ### 3. Electronic Architecture The device consists of two main electronic modules: * **The LED Module:** * Designed for low power consumption. * Equipped with internal current-limiting resistors to protect the LED from voltage spikes. * Polarity sensitive (though some AC/DC models include a bridge rectifier). * **The Contact Block:** * The switching mechanism is isolated from the light source. * Rated for low-current logic signals or higher current industrial relays (often up to 10A at 120V AC). * Uses **Silver (Ag)** contacts to ensure low resistance and long life cycles. --- ### 4. Wiring and Usage Typical wiring involves two separate circuits: 1. **Terminals X1 & X2:** Power for the LED illumination. 2. **Terminals 1 & 2 (or 3 & 4):** The switching circuit that controls the load (PLC input, relay coil, etc.). ```cpp // Typical Application Logic (PLC Example) IF (Switch_Pressed == TRUE) { LED_Indicator = ON; // Feedback loop Execute_Machine_Stop(); } ```
