The part number **M2AS1-A431-R2/CE** typically refers to a specialized industrial component, specifically an **Industrial Limit Switch** or a **Position Switch** manufactured by companies like **Bernstein AG** or similar industrial automation providers. Below is a breakdown of its technical specifications and electronic/mechanical characteristics. --- ### 1. Technical Specifications | Feature | Description | | :--- | :--- | | **Component Type** | Industrial Limit Switch / Position Switch | | **Actuator Type** | Roller Lever (likely adjustable or standard) | | **Contact Configuration** | 1 NO (Normally Open) + 1 NC (Normally Closed) | | **Switching Action** | Snap action or Slow action (Model dependent) | | **Housing Material** | Metal or high-grade Thermoplastic (Suffix specific) | | **Protection Class** | IP65 / IP67 (Dust tight and water-resistant) | | **Certification** | CE (Conformité Européenne) | --- ### 2. Breakdown of the Part Number Industrial part numbers are coded to provide specific information about the hardware: * **M2 / AS1**: Usually refers to the series and the housing size. "M" typically denotes a metal enclosure, while "AS" relates to the mounting standards. * **A431**: This is the internal code for the **Contact Block** configuration. It defines how many electrical poles are present and their default state (Open or Closed). * **R2**: This specifies the **Actuator type**. In this case, it usually refers to a **Roller Lever** or a specific radius arm used to trigger the switch physically. * **CE**: Indicates compliance with European health, safety, and environmental protection standards. --- ### 3. Electronic Characteristics * **Rated Operational Voltage (Ue):** Generally up to 240V AC or 24V DC. * **Conventional Thermal Current (Ithe):** Typically rated for 10A. * **Isolation Voltage (Ui):** Rated up to 400V or 500V to ensure safety between the electrical contacts and the outer casing. * **Electrical Life:** Designed for approximately 1 million switching cycles under load. --- ### 4. Common Applications These parts are vital in automation for sensing the presence or position of machinery: 1. **Conveyor Belts:** To detect when a package has reached a specific point. 2. **Safety Interlocks:** To ensure a machine guard is closed before the motor starts. 3. **End-of-Travel Sensing:** To prevent a CNC or mechanical arm from moving past its physical limit. ---
