The **M2RT-01-R2/K** is a specific model of an **Industrial Magnetic Proximity Sensor**, typically utilized in automation, safety interlocking, and position sensing. These devices act as non-contact switches that respond to the presence of a magnetic field. --- ### Technical Specifications & Components The "electronic" nature of this part is centered around its **Reed Switch** or **Hall Effect** internal construction, encapsulated in a rugged housing. | Feature | Specification Details | | :--- | :--- | | **Type** | Magnetic Proximity / Reed Switch | | **Output Type** | Normally Open (NO) / Normally Closed (NC) or Changeover | | **Max Voltage** | Typically up to 230V AC/DC (model dependent) | | **Max Current** | Generally 0.5A to 1.0A | | **Contact Material** | Rhodium or Ruthenium (for high reliability) | | **Housing Material** | Nickel-plated brass or High-grade Plastic | | **Sensing Distance** | 10mm to 30mm (depending on magnet strength) | --- ### Key Internal Parts 1. **The Reed Element:** Two ferromagnetic blades hermetically sealed in a glass envelope. When a magnet approaches, the blades become polarized and pull together to complete the circuit. 2. **Internal Resistor (Optional):** Some versions include a series resistor to protect the contacts from inrush current or a parallel resistor for line monitoring in safety systems. 3. **Encapsulation:** The internal electronics are potted with epoxy resin to protect against vibration, moisture, and dust (IP67 rating). 4. **Cable/Connector:** Features a multi-core cable or an M12 connector for integration into a PLC (Programmable Logic Controller) or relay circuit. --- ### Operating Principle The M2RT series operates on **Magnetism**. Unlike inductive sensors (which sense metal) or capacitive sensors (which sense density), this part requires a separate **Actuator (Magnet)**. * **Activation:** As the magnet moves within the "Operating Distance," the internal contact changes state. * **Deactivation:** As the magnet moves away beyond the "Release Distance," the contact returns to its original state. ### Typical Applications * **Safety Guards:** Ensuring a machine door is closed before operation. * **Pneumatic Cylinders:** Detecting the position of the internal piston. * **Elevator Leveling:** Sensing the floor position.
