Based on the model number **M2AS1-4231-R2/CE**, this part is an industrial-grade **Limit Switch** or **Position Sensor**, typically manufactured by companies specializing in automation components (such as *Bernstein AG* or similar industrial suppliers). Below is a breakdown of its electronic and mechanical parts, specifications, and design features. --- ### 1. Component Specifications The M2AS1 series usually follows a standardized modular design for industrial automation. | Feature | Specification | Description | | :--- | :--- | :--- | | **Contact Type** | Snap-Action | Quick switching to prevent arcing and ensure precision. | | **Contact Configuration** | 1 NO / 1 NC | 1 Normally Open and 1 Normally Closed circuit. | | **Voltage Rating (AC)** | Up to 240V | Standard industrial AC voltage compatibility. | | **Thermal Current (Ith)** | 10A | Maximum continuous current the contacts can handle. | | **Protection Class** | IP65 / IP67 | Dust-tight and protected against water jets/immersion. | | **Housing Material** | Metal / Die-cast | High durability for heavy-duty environments. | --- ### 2. Electronic & Internal Parts The "brains" and "muscles" of the switch consist of the following internal assemblies: * **Contact Block:** The core electrical component. It contains the silver-nickel or gold-plated contacts that open or close the circuit when the actuator is triggered. * **Terminal Screws:** Located inside the housing, these are used for wiring the switch to the PLC (Programmable Logic Controller) or motor starter. * **Galvanic Isolation:** The internal architecture ensures that the NC and NO circuits are electrically separated (Zb contact form), allowing for different potentials to be switched. * **Earth Terminal:** A dedicated grounding screw to ensure the metal housing is safely earthed. --- ### 3. Mechanical & External Parts The "R2" and "CE" suffixes provide clues about the physical interface: * **Actuator (R2):** Likely refers to a **Roller Lever** or **Offset Roller**. This part physically touches the moving machinery to trigger the internal electronic contacts. * **Cable Entry:** Usually features an M20 x 1.5 or PG13.5 threaded hole for industrial cable glands. * **Reset Mechanism:** Being an "M2" series, it often features a spring-return mechanism, meaning the switch returns to its original state once the force is removed. --- ### 4. Safety and Standards The **/CE** suffix indicates that the part meets the **European Conformity** standards, specifically: * **Low Voltage Directive (LVD):** Ensures the electrical safety of the device. * **Machinery Directive:** Ensures the switch can be used as a safety-related part of a control system. ---
