The **M2PHS2L-A1D-R2/Q** is a specific technical part number typically associated with **industrial control components**, specifically high-performance **Push Button Switches** or **Selector Switches** often manufactured by brands like IDEC or similar industrial automation suppliers. Below is a breakdown of its electronic and mechanical characteristics. ### 1. Component Overview This part belongs to a modular series where the part number defines the mounting size, operator type, contact configuration, and illumination. | Specification | Detail | | :--- | :--- | | **Series** | M2 Series (Commonly 22mm or 30mm industrial standard) | | **Component Type** | Illuminated Push Button / Selector Switch | | **Mounting Diameter** | Typically 22mm (Standard industrial hole size) | | **Action Type** | Momentary or Maintained (Depending on the "L" suffix) | --- ### 2. Part Number Breakdown (Functional Logic) In industrial switching, each character in the string represents a specific electronic or physical attribute: * **M2P**: Refers to the series type (Modular Pilot device). * **HS**: Often denotes a "High Square" or "Selector" head style. * **2L**: Indicates the illumination type. "L" usually stands for **LED**. * **A1D**: * **A**: Contact material (often Silver or Gold-clad). * **1**: Number of contact blocks (1 NO or 1 NC). * **D**: Voltage rating (commonly **24V AC/DC** for LED units). * **R2**: Color code. "R" typically stands for **Red**. * **Q**: Quick-connect or specialized terminal designation. --- ### 3. Key Electronic Specifications These devices are designed for integration into Control Panels, PLCs, and Safety circuits. | Feature | Description | | :--- | :--- | | **Rated Operational Voltage** | 24V AC/DC (LED circuit); up to 250V for contacts. | | **Contact Resistance** | Typically < 50mΩ. | | **Insulation Resistance** | > 100MΩ at 500V DC. | | **Illumination Technology** | Surface Mount or Integrated LED for long life (>50,000 hours). | | **Ingress Protection** | Usually **IP65** (Oil-tight and Water-tight from the front). | --- ### 4. Typical Wiring Diagram (Simplified) Industrial switches separate the **Lamp Circuit** from the **Switching Circuit**. ```text Terminal X1 (+) ---- [ Internal LED ] ---- Terminal X2 (-) (Power for Red Light) Terminal 13 (NO) ---- [ Contact Gap ] ---- Terminal 14 (NO) (Switching Logic) ``` --- ### 5. Application Areas * **PLC Input Modules:** Sending signals to start or stop a process. * **Emergency Indicators:** Using the Red LED to indicate a fault state. * **Human-Machine Interface (HMI):** Physical override buttons on CNC machines or assembly lines.
