The part number **M2AS1-5331-R2/CE** typically refers to a specialized **Industrial Micro-Switch** or a **Limit Switch** component, often manufactured by companies like **Moujen Electric** or similar industrial control brands. Below is a detailed breakdown of the electronic and mechanical specifications for this type of component. --- ### 1. General Specifications This part is designed for precision switching in automated machinery, security systems, and industrial control panels. | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Micro-Switch / Snap-Action Switch | | **Contact Form** | SPDT (Single Pole Double Throw) | | **Actuator Type** | Short Roller Lever | | **Current Rating** | 10A to 15A (at 250VAC) | | **Certification** | CE (European Conformity), RoHS Compliant | --- ### 2. Internal Electronic Structure The "M2" series usually follows a standard internal construction: * **Contacts:** Typically made of Silver Alloy to minimize electrical resistance and prevent oxidation during high-frequency switching. * **Terminals:** * **COM (Common):** The input terminal. * **NO (Normally Open):** The circuit is open until the lever is pressed. * **NC (Normally Closed):** The circuit is closed until the lever is pressed. * **Switching Mechanism:** Uses a "Snap-Action" spring mechanism. This ensures that the transition between NO and NC is instantaneous, regardless of the speed of the physical actuator, reducing electrical arcing. --- ### 3. Part Number Breakdown While manufacturer codes vary slightly, the nomenclature usually represents the following: | Code | Meaning | | :--- | :--- | | **M2** | Series designation (Standard Micro-switch housing). | | **AS** | Solder terminal or specific mounting configuration. | | **5331** | Specific actuator style (e.g., Short Roller Lever). | | **R2** | Modification code (can indicate specialized spring force or contact material). | | **CE** | Meets European safety and environmental standards. | --- ### 4. Technical Characteristics * **Operating Force (OF):** Usually rated between 150g and 200g. * **Mechanical Life:** Typically rated for 10,000,000 cycles. * **Electrical Life:** Typically rated for 100,000 to 500,000 cycles depending on the load. * **Insulation Resistance:** 100MΩ min. (at 500VDC). * **Dielectric Strength:** 1,000VAC for 1 minute between non-continuous terminals. --- ### 5. Common Applications * **Industrial Automation:** Used as a limit switch to detect the position of moving parts. * **Safety Interlocks:** Ensuring a machine door is closed before operation. * **Consumer Appliances:** Detecting door positions in microwave ovens or washing machines.
