The **M2XT2-2V1-R/BN** is a specific part number belonging to the **M2XT2 series** of high-performance industrial components, typically associated with **Schmersal** (specifically their command and signaling device line). These parts are designed for heavy-duty industrial control panels, ensuring reliable human-machine interface (HMI) interaction in harsh environments. --- ### 1. Component Overview The M2XT2 series generally refers to **double push-button actuators**. These are used to control two separate functions (such as "Start" and "Stop" or "Up" and "Down") within a single 22.5 mm cutout, saving panel space. ### 2. Technical Specifications Below is a breakdown of the typical electronic and mechanical characteristics for this series: | Feature | Specification | | :--- | :--- | | **Mounting Diameter** | 22.3 mm (Standard industrial size) | | **Button Type** | Double Push-button (Extended/Flush) | | **Material** | Chrome-plated metal or high-grade plastic (Heavy-duty) | | **Protection Class** | IP67 / IP69K (Waterproof & Dust-tight) | | **Illumination** | Optional (LED compatible) | | **Operating Temp** | -25°C to +80°C | ### 3. Part Number Breakdown (Nomenclature) While specific internal codes vary by manufacturer, the suffix codes for this part usually indicate: * **M2XT2:** The basic series identifier for a twin-pushbutton actuator. * **2V1:** Configuration of the button heights (e.g., one flush, one extended). * **R/BN:** Color coding. * **R:** Red (often used for Stop/Off). * **BN:** Green (often used for Start/On - *Note: BN is sometimes used for Black in specific German nomenclature codes, but Green is standard for twin starts*). --- ### 4. Electronic Connection (Contact Blocks) It is important to note that the **M2XT2-2V1-R/BN** is the **actuator head**. To make it functional, it must be paired with specific electronic contact blocks: 1. **NO (Normally Open):** Used for starting circuits. 2. **NC (Normally Closed):** Used for stopping/safety circuits. 3. **LED Element:** If the device is illuminated, a separate voltage-specific LED block (24V AC/DC or 230V AC) is snapped onto the back of the flange. ### 5. Application Areas * **Industrial Control Panels:** Controlling motors or machinery. * **Food Processing:** Due to the IP69K rating, it can withstand high-pressure washdowns. * **Material Handling:** Conveyor belt start/stop stations. ---
