The **ALV-5W23-R** is a specific electronic component, typically categorized as a **Micro-Switch** or **Snap Action Switch**, often used in industrial controls, consumer electronics, and automotive applications. It is part of a series known for high reliability and compact design. --- ### 1. Key Technical Specifications Below are the general electrical and mechanical characteristics associated with this part number: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Snap Action / Micro-Switch | | **Circuitry** | SPDT (Single Pole Double Throw) | | **Current Rating** | Typically 5A to 10A (Depending on voltage) | | **Voltage Rating** | 125V AC / 250V AC | | **Actuator Type** | Pin Plunger (Standard) | | **Termination Style** | Solder Terminals / Quick Connect | | **Operating Force** | ~1.47 N (Approx. 150gf) | | **Mounting Type** | Through-hole / Screw Mount | --- ### 2. Physical Construction The "R" suffix often denotes specific orientation or RoHS compliance depending on the manufacturer (commonly associated with brands like **Panasonic** or **Omron** variants). * **Housing:** High-grade thermoplastic (PBT or Phenolic) to withstand heat. * **Contacts:** Usually Silver alloy to ensure low contact resistance and prevent oxidation. * **Mechanism:** A "Snap-Action" spring mechanism that ensures rapid transfer of contacts regardless of the speed of the actuator. --- ### 3. Pinout Configuration As an SPDT switch, the ALV-5W23-R typically features three terminals: 1. **COM (Common):** The input terminal. 2. **NC (Normally Closed):** Connected to COM when the plunger is at rest. 3. **NO (Normally Open):** Connected to COM only when the plunger is depressed. --- ### 4. Typical Applications * **Safety Interlocks:** Detecting if a door or panel is closed (e.g., microwaves, 3D printers). * **Limit Switching:** Defining the end-of-travel for CNC machines or motorized gates. * **Control Panels:** Used as a durable tactile button for industrial interfaces. ---
