Based on your inquiry, the **M2RT-31-R/N** is a specific model of a **Magnetic Proximity Sensor** (often referred to as a Reed Switch sensor), typically manufactured by companies like **Mecatix** or **M-System**. These sensors are used for non-contact position detection. --- ### 1. General Specifications The part number breaks down into specific electrical characteristics. Below is a summary of its electronic profile: | Feature | Specification | | :--- | :--- | | **Type** | Magnetic Proximity Sensor / Reed Switch | | **Contact Type** | NO (Normally Open) | | **Switching Voltage** | Max 100V DC / 125V AC | | **Switching Current** | Max 0.5A | | **Power Rating** | 10W / 10VA | | **Operating Temperature** | -10°C to +70°C | | **Housing Material** | Plastic (usually cylindrical or rectangular) | --- ### 2. Key Electronic Components & Operation The M2RT-31-R/N functions through several internal electronic principles: #### A. The Reed Switch Element Inside the housing are two ferromagnetic blades (reeds) hermetically sealed in a glass tube. * **Activation:** When a magnetic field (from a permanent magnet) comes within range, the blades become polarized and pull together. * **Circuit Completion:** This closes the circuit, allowing current to flow to the PLC or control unit. #### B. Output Characteristics ("/R/N") * **R (Reed):** Indicates a mechanical reed contact rather than a solid-state (Hall Effect) sensor. This provides potential-free contacts. * **N (Normally Open):** The default state of the switch is "Open" (Off). It only closes when the magnet is present. --- ### 3.
