The part number **M3SWVS-B5Y-R** identifies a specific industrial-grade **Indicator Assembly** or **Illuminated Selector Switch**, typically associated with manufacturers like Omron or similar industrial component providers. These parts are used in control panels to provide visual status feedback. --- ### 1. Component Breakdown The alphanumeric code follows a specific nomenclature that defines the physical and electrical characteristics of the unit. | Code Segment | Feature Type | Description | | :--- | :--- | :--- | | **M3S** | Series Prefix | Designates the physical form factor and mounting style (usually 16mm or 22mm). | | **WVS** | Actuator Style | Refers to a Wide-View or V-shape illuminated lens/switch head. | | **B5** | Voltage/Lamp | Indicates the operating voltage (Commonly 5V or 12V DC). | | **Y** | Color Code | **Yellow** (Amber) illumination. | | **R** | Configuration | Reset style or specific resistor integration for LED protection. | --- ### 2. Key Electronic Specifications These units are designed to integrate directly into logic circuits or PLCs (Programmable Logic Controllers). * **Illumination Source:** High-efficiency LED (Internal). * **Operating Voltage:** Typically 5V DC (indicated by the 'B5' segment). * **Current Consumption:** Usually ranges between **10mA to 25mA**, making it compatible with low-power transistor outputs. * **Mounting Diameter:** Standardized for industrial panels (typically 16mm). * **Termination:** Solder terminals or PCB-mount pins depending on the specific sub-variant. --- ### 3. Application Use Cases The **M3SWVS-B5Y-R** is used in environments where reliable visual signaling is required: 1. **Status Indication:** Used as a "Warning" or "Standby" light due to its yellow color. 2. **Human-Machine Interface (HMI):** Integrated into custom control boxes for machinery. 3. **Circuit Monitoring:** Provides a visual confirmation that a specific sub-circuit (operating at 5V) is active. --- ### 4.
