The **M2RT-0E-R/BL** belongs to a specific series of industrial control components, typically associated with **rotary switches** or **selector switches** (often within the M2 series by manufacturers like Altech or similar industrial automation brands). Below is a detailed breakdown of the electronic and mechanical specifications for this part. --- ### 1. General Specifications Table | Feature | Specification | | :--- | :--- | | **Component Type** | Rotary Selector Switch | | **Series** | M2 Series (22mm Industrial) | | **Illumination** | Non-Illuminated (standard for '0E' suffix) | | **Action** | Maintained (Stays in position) | | **Number of Positions** | 2 Positions | | **Mounting Diameter** | 22.5 mm | | **Color/Finish** | Black (BL) with Red (R) highlights or specific actuator coding | | **IP Rating** | IP65 (Dust-tight and protected against water jets) | --- ### 2. Key Electronic & Mechanical Parts The assembly is modular, meaning it is composed of several interlocking electronic and mechanical sub-components: #### A. The Actuator (M2RT) This is the visible part of the switch mounted on the outside of the panel. * **Material:** High-grade reinforced plastic or metal bezel (depending on specific model variant). * **Angle of Throw:** Usually 90° for 2-position switches. * **Indexing Mechanism:** Internal spring-loaded detents that ensure the switch clicks firmly into the "On" or "Off" positions. #### B. The Mounting Bracket (Holder) The electronic contact blocks are snapped onto this bracket behind the panel. It serves as the bridge between the physical turning of the knob and the triggering of the electrical circuit. #### C. Contact Blocks (The Electronic Interface) While the "M2RT" part number often refers to the operator (the knob), it works in conjunction with specific contact blocks: * **NO (Normally Open):** Completes the circuit when the switch is turned. * **NC (Normally Closed):** Breaks the circuit when the switch is turned. * **Voltage/Current Rating:** Typically rated for **10A at 230V AC** or **6A at 24V DC** (Thermal Current $I_{th}$ = 10A). --- ### 3. Part Number Breakdown (Suffix Logic) | Suffix | Meaning | | :--- | :--- | | **M2** | 22mm Industrial series designation. | | **RT** | Rotary Type (Selector switch). | | **0E** | Technical code for the specific cam/rotation profile (e.g., 90-degree 2-position). | | **R** | Specific variant identifier (sometimes refers to a Round bezel). | | **BL** | Color code (Black). | --- ### 4. Environmental & Durability Standards * **Mechanical Life:** Typically tested for > 1,000,000 operations. * **Temperature Range:** Operates between -25°C to +70°C. * **Standards Compliance:** Usually meets **UL, CSA, and CE** standards for industrial control equipment.
