The **M2RTS-S-32-R2** is a specific model within the family of industrial sensors, typically categorized as a **Magnetic Proximity Sensor** or a **Reed Switch**. These components are widely used in industrial automation for position sensing, safety interlocking, and pneumatic cylinder feedback. --- ### 1. Technical Specifications Overview The following table outlines the typical electrical and mechanical characteristics of the M2RTS series: | Parameter | Specification | | :--- | :--- | | **Sensor Type** | Magnetic Reed Switch | | **Operating Voltage** | 5V to 240V AC/DC | | **Switching Current** | 100mA Max (Load dependent) | | **Contact Capacity** | 10W Max | | **Voltage Drop** | 2.5V Max | | **Indicator Lamp** | Red LED (Standard) | | **Operating Temperature** | -10°C to +70°C | | **Protection Class** | IP67 (Dust and Water resistant) | --- ### 2. Breakdown of the Model Code The nomenclature "M2RTS-S-32-R2" provides specific details about its build: * **M2RTS**: The series identifier (Magnetic Reed Type Sensor). * **-S**: Indicates the physical size or sensitivity range (typically "Small" or standard slim-fit). * **-32**: This usually refers to the internal reed element type or the specific cylinder groove compatibility (commonly used with ISO/VDMA standard pneumatic cylinders). * **-R2**: Specifies the lead wire length (2 meters) and the termination type (usually pre-wired pigtail). --- ### 3. Electronic Operating Principle The device operates on the **Reed Principle**. Unlike Hall Effect sensors (which are solid-state/active), a Reed Switch is a passive mechanical component: 1. **Magnet Detection**: When a magnet (usually mounted on a piston inside a cylinder) moves close to the sensor, the magnetic field pulls two ferromagnetic reeds together. 2. **Circuit Completion**: The physical contact of these reeds completes the electrical circuit, allowing current to flow to a PLC (Programmable Logic Controller) or a relay. 3. **Visual Feedback**: Most R2 models include a built-in LED in series with the switch, which illuminates when the circuit is closed to assist in troubleshooting and alignment. --- ### 4. Wiring Diagram and Logic The M2RTS-S-32-R2 is a **2-wire** device. This means it is wired in series with the load. ```markdown [Power Source (+)] ---- [Load/PLC Input] ---- [Brown Wire] | [Sensor Body] | [Power Source (-)] -------------------------- [Blue Wire] ``` **Note:** Because it is a 2-wire sensor, there is a small "leakage current" and a "voltage drop." Ensure your PLC input threshold is compatible with a ~2.5V drop. ---
