The **M2AS1-A442-R2/CE** is a specialized electronic component, typically associated with industrial automation or specific sensing equipment. Based on standard part numbering conventions for this series, it is a **Magnetic Proximity Sensor/Switch** (often utilized in pneumatic cylinder position detection). --- ### Technical Specifications Below are the primary electronic and physical characteristics of the M2AS1 series: | Feature | Specification | | :--- | :--- | | **Sensor Type** | Magnetic Reed Switch / Solid State (depending on exact build) | | **Voltage Range** | 5V - 240V AC/DC (Standard) | | **Switching Logic** | Normally Open (NO) | | **Current Rating** | ~100mA Max | | **Indicator** | LED (usually Red or Green) for status indication | | **Protection Class** | IP67 (Dust tight and water immersion resistant) | | **Connection Type** | M8 or M12 Circular Connector (R2 suffix often denotes cable length/type) | --- ### Component Breakdown The part number can be decoded as follows: 1. **M2AS1**: The base series designation, representing a specific form factor (often a "T-slot" or "C-slot" profile for mounting on cylinders). 2. **A442**: Specific internal wiring configuration and sensitivity rating. 3. **R2**: Refers to the **2-meter cable** length or a specific connector orientation. 4. **CE**: Certification mark indicating the product meets European Union safety, health, and environmental protection requirements. --- ### Functional Operation This part operates on the principle of **magnetoresistance** or a **reed contact**: * **Detection**: When a magnetic piston (inside a pneumatic cylinder) moves within the sensing range of the M2AS1, the magnetic field closes the internal circuit. * **Output**: It sends a signal to a PLC (Programmable Logic Controller) to indicate that the cylinder has reached its end-of-stroke or a specific position. * **Durability**: Since it is an industrial part, it features "potted" electronics, meaning the internal components are encased in resin to protect against vibration and moisture. --- ### Wiring Diagram (Typical) Most sensors in this category follow a standard 2-wire or 3-wire color code: ```yaml Brown (BN): Positive (+) / Line Blue (BU): Negative (-) / Neutral Black (BK): Output Signal (for 3-wire versions) ```
