Based on the part number **M2PHS2L-A1D-R2**, this appears to be a specific alphanumeric code typically associated with **Industrial HMI (Human Machine Interface) components** or **Push Button Switch assemblies**, often manufactured by companies like IDEC or similar industrial automation brands. --- ### 1. Component Breakdown The part number is structured to define the mechanical and electrical characteristics of the device. | Segment | Typical Meaning | Description | | :--- | :--- | :--- | | **M2P** | Series/Body Style | Often denotes a 22mm or 16mm miniature pilot light or switch body. | | **HS2L** | Function/Head | **H**: Lever/Handle; **S2**: 2-Position selector; **L**: Lever type. | | **A1D** | Contact Block | **A**: Standard contacts; **1**: 1NO (Normally Open); **D**: DC voltage or specific wiring. | | **R2** | Color/Revision | **R**: Red actuator; **2**: Revision level or secondary feature. | --- ### 2. Electrical Specifications While specific datasheets vary by manufacturer, parts in this category generally follow these industrial standards: * **Contact Rating:** Typically 24V DC at 1A or 120V AC at 5A (depending on the contact block). * **Insulation Resistance:** 100MΩ minimum (500V DC megger). * **Dielectric Strength:** 2,500V AC for 1 minute between live and dead parts. * **Operating Temperature:** -25°C to +50°C (without freezing). * **Mechanical Life:** 250,000 to 500,000 operations. --- ### 3. Key Electronic Features 1. **Contact Block Configuration:** The "1D" or "A1" portion usually indicates the number of poles. This part likely utilizes a modular contact block that can be snapped onto the back of the actuator. 2. **Illumination (If applicable):** If the part includes an "L" for LED, it contains a built-in current-limiting resistor and a bridge rectifier to allow for AC/DC operation at specific voltages (usually 6V, 12V, or 24V). 3. **Terminal Type:** Most R2 revision parts use **IP20 finger-safe screw terminals** or **PC Board terminals**, ensuring safe wiring in dense control panels. --- ### 4. Typical Applications * **Control Panels:** Used as a selector switch to toggle between "Auto" and "Manual" modes. * **Industrial Machinery:** Used for emergency stop or status signaling. * **PLCs:** Acts as a digital input provider for programmable logic controllers.
