The **M2AS1-A112-R2/CE** is a specific part number belonging to a series of industrial **Limit Switches** (often associated with brands like Moujen or similar Asian industrial component manufacturers). These are electromechanical devices used to detect the presence, position, or end-of-travel of an object. --- ### 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Component Type** | Industrial Limit Switch / Micro Switch | | **Actuator Type** | Roller Lever (Usually adjustable or standard) | | **Contact Configuration** | 1NO + 1NC (1 Normally Open + 1 Normally Closed) | | **Current Rating** | Typically 5A to 10A (depending on voltage) | | **Voltage Rating** | 125V / 250V AC | | **Terminal Type** | Screw Terminals | | **Certification** | CE Marked (Compliant with EU safety standards) | | **Housing Material** | Zinc Die-cast or High-grade Plastic (Series dependent) | --- ### 2. Breakdown of the Part Number While specific manufacturer codes vary slightly, the nomenclature generally breaks down as follows: * **M2AS**: The series designation (General purpose, compact limit switch). * **1-A**: Indicates the contact block type and internal mechanism (Snap action). * **112**: Refers to the **Actuator Head**. In this series, "112" usually denotes a **Roller Lever** (often a short or standard length arm with a plastic or metal wheel). * **R2**: Revision code or specific mounting/cable entry orientation. * **CE**: Confirms the part meets European Conformity standards for safety and environmental protection. --- ### 3. Electronic & Mechanical Function The device operates on a **Snap Action** principle. When the roller lever is depressed by a moving machine part: 1. The internal spring mechanism reaches a trip point. 2. The contacts instantly flip from their resting state (NC opens, NO closes). 3. This sends an electrical signal to a PLC (Programmable Logic Controller) or a motor starter to stop or start a process. ### 4. Common Applications * **Conveyor Belts**: Detecting the arrival of a package. * **CNC Machinery**: Establishing the "Home" position or limit of axis travel. * **Elevators/Lifts**: Sensing the floor level or door closure. * **Safety Interlocks**: Ensuring a protective guard is closed before a machine starts. ---
