The **M2AS1-A211-R2** is a specialized electronic component, typically categorized as a **Magnetic Sensor** or a **Proximity Switch**, often used in industrial automation for position sensing. Below is a breakdown of its technical specifications and electronic characteristics. --- ### 1. Technical Specifications This part is designed to detect the presence of a magnetic field (usually from a permanent magnet) to trigger a circuit. | Parameter | Description | | :--- | :--- | | **Component Type** | Magnetic Proximity Sensor / Reed Switch | | **Contact Form** | Form A (Normally Open - NO) | | **Switching Voltage** | Usually up to 200V DC / 140V AC | | **Switching Current** | Max 0.5A | | **Contact Rating** | 10W / 10VA | | **Housing Material** | Plastic / Thermoplastic | | **Mounting Style** | Surface Mount / Screw Mount (Application dependent) | --- ### 2. Key Electronic Features * **Non-Contact Operation:** Since it operates via magnetic induction, there is no physical contact between the sensor and the target, significantly reducing mechanical wear and tear. * **Passive Sensing:** Most models in this series do not require a power supply to operate; they act as a simple mechanical switch triggered by magnetism. * **Environmental Sealing:** These parts are often hermetically sealed, making them resistant to dust, moisture, and corrosion. * **Fast Response Time:** Provides rapid switching, typically in the millisecond (ms) range, suitable for high-speed counting or limit-switching. --- ### 3. Connection Diagram (General) The electronic integration is straightforward. Below is a representation of how it is typically wired into a control circuit: ```mermaid graph LR A[Power Source] --> B[M2AS1-A211-R2 Sensor] B --> C[Load / PLC Input] C --> D[Ground/Common] ``` ### 4. Typical Applications 1. **Industrial Automation:** Detecting the end-of-stroke position in pneumatic cylinders. 2. **Security Systems:** Sensing if a door or window is open or closed. 3. **Appliance Control:** Used in white goods (washers/dryers) to detect lid closure. 4. **Flow Meters:** Detecting the rotation of internal magnetized turbine blades. ---
