The **M2RT-00-R/CE** is a specialized electronic component, typically categorized as a **Magnetic Proximity Sensor** or a **Magnetic Reed Switch**, often utilized in industrial automation and pneumatic cylinder position sensing. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. Technical Specifications The M2RT series is designed to detect the presence of a magnetic field (usually from a piston inside a cylinder) and close an electrical circuit. | Feature | Specification | | :--- | :--- | | **Sensor Type** | Reed Switch (SPST - Single Pole Single Throw) | | **Operating Voltage** | 5V to 240V AC/DC | | **Switching Current** | 100mA Max | | **Switching Rating** | 10W Max | | **Voltage Drop** | 2.5V Max | | **Indicator** | Red LED (Standard for 'R' models) | | **Protection Class** | IP67 (Dust tight and water immersion) | | **Temperature Range** | -10°C to +70°C | --- ### 2. Internal Electronic Components The device consists of three primary internal stages: 1. **The Reed Element:** Two ferromagnetic blades hermetically sealed in a glass envelope. When a magnet approaches, the blades become opposite poles and pull together, completing the circuit. 2. **LED Indicator Circuit:** A small Light Emitting Diode connected in series (or parallel with a resistor) that illuminates when the circuit is closed, providing visual feedback for troubleshooting. 3. **Protection Circuitry:** Usually includes a varistor or a diode to protect the reed contacts from "arcing" or back-EMF when switching inductive loads (like small relays). --- ### 3. Wiring Configuration The "00" in the part number usually refers to a specific lead wire configuration (typically a 2-wire setup). ```mermaid [Power Source (+)] ---- [Brown Wire] ---- (M2RT Sensor) ---- [Blue Wire] ---- [Load/PLC Input] ---- [Power Source (-)] ``` * **Brown Wire:** Positive (+) / Line * **Blue Wire:** Negative (-) / Neutral * **Note:** Since it is a 2-wire Reed switch, it does not have a dedicated ground and must be wired in series with the load. --- ### 4. Key Applications * **Pneumatic Cylinders:** Mounted on the "T-slot" of a cylinder to detect when the piston has reached its end-of-stroke. * **Safety Interlocks:** Detecting if a protective gate (with a magnet attached) is closed. * **Pulse Counting:** Measuring the speed of a rotating shaft equipped with a magnet. ---
