The **W2PV-C3S1B-R** is a specific part number belonging to the **W2PV Series** of industrial push-button switches manufactured by **IDEC**. This component is designed for high-performance control panels, offering a modular design and robust environmental protection. --- ### 1. General Specifications The W2PV series is known for its compact depth and high-quality tactile feedback. Below is a breakdown of the technical characteristics: | Feature | Specification | |:---|:---| | **Series** | W2PV (Flush Silhouette) | | **Shape** | Round, Flush Mount | | **Mounting Hole** | Ø22mm (Standard Industrial Size) | | **Illumination** | Non-Illuminated (standard for this suffix) | | **Material** | Plastic Bezel | | **Operation** | Momentary (Spring Return) | | **Contact Configuration** | 1 Normally Open (1NO) | --- ### 2. Part Number Breakdown (Nomenclature) Understanding the alphanumeric code helps identify the exact electronic and mechanical properties: * **W2PV**: The series identifier (Flush Silhouette Pushbuttons). * **C**: Denotes a Round shape with a Plastic Bezel. * **3**: Indicates the function (Momentary - the button returns when released). * **S1**: Contact block configuration (1NO - Single Normally Open contact). * **B**: Button Color (Black). * **R**: Potential packaging or revision indicator (often refers to RoHS compliance or specific regional distribution). --- ### 3. Electrical Characteristics These switches are rated for industrial control circuits: * **Insulation Resistance:** 100 MΩ minimum (500V DC megger). * **Contact Resistance:** 50 mΩ maximum (initial value). * **Operating Voltage:** Up to 600V AC/DC (standard rating for IDEC HW/W series contact blocks). * **Mechanical Durability:** Approx. 5,000,000 operations. * **Degree of Protection:** IP65 / NEMA 4X (Water-proof and Oil-tight). --- ### 4. Key Advantages 1. **Compact Design:** Requires very little depth behind the panel compared to traditional switches. 2. **Modular Construction:** The contact blocks can be removed or added, allowing for easy maintenance and circuit customization. 3. **Safety:** Fingersafe (IP20) terminals reduce the risk of accidental electric shock during wiring.
