The **W2PV-C1A1-R** is a specific part number belonging to a series of industrial-grade **Limit Switches** (specifically the W2PV series) often utilized in automation, security, and position-sensing applications. --- ### 1. Component Overview The W2PV-C1A1-R is a mechanical switch designed to convert physical motion into an electrical signal. It is characterized by its compact form factor and high durability. ### 2. Technical Specifications The following table outlines the primary electronic and physical characteristics of this part: | Feature | Specification | | :--- | :--- | | **Component Type** | Limit Switch / Micro Switch | | **Contact Form** | SPDT (Single Pole Double Throw) | | **Actuator Type** | Pin Plunger (Standard) | | **Current Rating** | Typically 0.1A to 5A (model dependent) | | **Voltage Rating** | 125VAC / 250VAC | | **Termination Style** | Solder or Quick Connect terminals | | **Operating Force** | High Precision / Low Force | | **Environmental Rating** | IP40 (Standard protection against dust) | --- ### 3. Internal Circuitry The W2PV-C1A1-R typically operates on a **Changeover (SPDT)** mechanism. This allows it to be used in two different configurations: * **Normally Open (NO):** The circuit is completed only when the plunger is pressed. * **Normally Closed (NC):** The circuit is broken when the plunger is pressed. ```mermaid graph LR A[Common Terminal] --- B(Internal Spring) B --> C[NC Terminal] B -.-> D[NO Terminal] subgraph Action E[Physical Pressure] end ``` --- ### 4. Typical Applications 1. **Industrial Machinery:** Detecting the end-of-travel for a moving arm or conveyor. 2. **Safety Interlocks:** Ensuring a machine door is closed before the power can be engaged. 3. **Office Equipment:** Detecting paper jams or door positions in large printers/copiers. 4. **Home Appliances:** Used in microwave door latches or washing machine lids. --- ### 5. Key Features * **Reliability:** Engineered for millions of mechanical cycles. * **Fast Switching:** The internal "snap-action" mechanism ensures the contacts move rapidly regardless of the speed of the actuator. * **Compact Design:** Designed for space-constrained PCB or panel mounting.
