The part number **M2AS1-5312-R2/CE** typically refers to an industrial-grade **Magnetic Sensor or Proximity Switch**, often used in automation and security systems. Below is a detailed breakdown of its electronic characteristics and specifications. ### 1. Component Identification This device is a magnetic contact/sensor used to detect the opening and closing of doors, windows, or moving machinery parts. | Feature | Specification | | :--- | :--- | | **Type** | Magnetic Proximity Sensor / Surface Mount Contact | | **Contact Configuration** | Normally Open (NO) / SPST | | **Mounting** | Screw-on / Surface Mount | | **Housing Material** | High-impact ABS Plastic or Aluminum (variant dependent) | | **Standard** | CE Certified (indicated by /CE) | --- ### 2. Electrical Specifications These parts are designed for low-voltage signal loops rather than direct power switching. * **Max Switching Voltage:** 100V DC/AC * **Max Switching Current:** 0.5A * **Contact Power Rating:** 10W (Max) * **Gap Distance:** Typically 15mm to 25mm (The distance at which the magnet triggers the internal reed switch). * **Initial Contact Resistance:** < 200 mΩ --- ### 3. Key Internal Components The electronic functionality relies on two primary elements: 1. **The Reed Switch:** A glass capsule containing two ferromagnetic blades. When a magnetic field (from the companion magnet) is brought close, the blades touch, closing the circuit. 2. **The Actuator (Magnet):** A permanent magnet housed in a matching casing. 3. **Terminal Block/Wires:** The "R2" designation often refers to a specific wiring or terminal configuration (e.g., 2-wire leads or a specific resistor integration). --- ### 4. Technical Diagram Representation In a schematic, this part functions as a simple switch controlled by magnetism. ```mermaid graph LR A[Power Source] --- B[Terminal 1] B --- C{Reed Switch} C --- D[Terminal 2] D --- E[Control Panel/PLC] ``` ### 5. Application Areas * **Access Control:** Detecting unauthorized entry. * **Industrial Automation:** Confirming that a safety guard is closed before a machine starts. * **Smart Buildings:** Feedback for HVAC systems to turn off air conditioning if a window is open. ---
