## Overview of M22-DR-R The **M22-DR-R** is a high-quality industrial pilot device manufactured by **Eaton (Moeller)**. It belongs to the **M22 (RMQ-Titan)** series, which is known for its modular design and ergonomic features. Specifically, the "M22-DR-R" refers to the **actuator head** of a pushbutton. --- ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Part Number** | M22-DR-R | | **Color** | Red | | **Function** | Maintained (Stay-put) | | **Diameter** | 22.5 mm (Standard Industrial Size) | | **Shape** | Round, Flush | | **IP Rating** | IP66, IP67, IP69K (High Protection) | | **Mounting** | Front Mount | --- ### Key Electronic & Mechanical Components The M22-DR-R is part of a modular system. To function as an electronic switch, it must be paired with other components: #### 1. The Actuator (M22-DR-R) This is the red button itself. The "DR" designation indicates **maintained** action—meaning when you press it, it stays down until you press it again to release it. #### 2. The Fixing Adapter (M22-A) This component connects the pushbutton head to the electronic contact blocks. It snaps onto the back of the actuator. #### 3. Contact Blocks (M22-K series) These are the actual "electronic" parts that open or close the circuit. * **M22-K10:** Normally Open (NO) contact. * **M22-K01:** Normally Closed (NC) contact. * The modularity allows you to stack multiple contact blocks depending on the logic required for your machinery. #### 4. LED Elements (Optional) If you require the button to be illuminated, you would use an **M22-LED** element. However, note that the M22-DR-R is a solid red button; for illumination, an **M22-DRL-R** (the "L" standing for Light) is typically used. --- ### Applications * **Control Panels:** Used for "Stop" functions where the button needs to remain depressed. * **Industrial Automation:** Signaling state changes in PLC systems. * **Harsh Environments:** Due to the IP69K rating, it can withstand high-pressure washdowns and heavy dust. ---
