The part number **M2AS1-5113-R2** generally refers to a specific type of **Rotary Switch** or **Selector Switch**, often utilized in industrial control panels or specialized consumer electronics. Below is a detailed breakdown of the electronic and mechanical characteristics typically associated with this component. --- ### 1. Component Overview The M2AS series is characterized by its modular design, allowing for different contact blocks to be attached to the operator head. | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Rotary Selector Switch | | **Mounting Diameter** | Usually 22mm or 30mm (standard industrial size) | | **Positions** | 2-Position or 3-Position (Stay-put/Maintained) | | **Contact Configuration** | 1NO (Normally Open) or 1NC (Normally Closed) base | | **Illumination** | Non-Illuminated (standard for the -R2 suffix) | --- ### 2. Key Electronic Parts & Composition The unit is composed of three primary sub-assemblies: #### A. The Operator Head The physical knob or lever that the user turns. - **Material:** Often reinforced plastic or chrome-plated metal. - **Action:** Maintained (stays in position) or Spring Return (momentary). #### B. The Contact Block This is the electrical "heart" of the switch. - **Terminals:** Screw-type terminals for wire connection. - **Rating:** Typically rated for **10A at 240VAC** or **6A at 24VDC**. - **Conductivity:** Contacts are often silver-alloy to prevent oxidation and ensure a low-resistance path. #### C. The Mounting Collar The bridge that connects the operator head through the panel to the contact blocks. It ensures the mechanical torque from the knob is translated into the physical movement of the electrical contacts. --- ### 3. Technical Specifications Typical electrical limits for this class of industrial switch: ```json { "electrical_life": "500,000 cycles", "mechanical_life": "1,000,000 cycles", "insulation_resistance": "100MΩ min at 500VDC", "dielectric_strength": "2500VAC for 1 minute", "operating_temperature": "-25°C to +70°C" } ``` --- ### 4. Application Areas Due to its rugged design, the M2AS1-5113-R2 is commonly found in: 1. **CNC Machinery:** To toggle between manual and automatic modes. 2. **Power Distribution Boards:** For isolating circuits or selecting phases. 3. **Safety Systems:** As a lockable selector to prevent unauthorized operation. ---
