Based on the technical nomenclature provided, the part **M2AS1-A223-R2/N** appears to be a specific configuration of a **rotary selector switch** or a **push-button industrial control component**, likely from a manufacturer such as **IDEC** or a similar industrial automation brand. Below is a breakdown of the typical electronic and mechanical specifications for this type of component. --- ### 1. Component Overview This part is an industrial-grade control switch designed for panel mounting. It is used to open or close electrical circuits manually. | Feature | Specification (Typical) | | :--- | :--- | | **Type** | Selector Switch / Control Unit | | **Mounting Diameter** | 22mm (Standard Industrial size) | | **Contact Configuration** | 2NO (2 Normally Open) or mixed depending on suffix | | **Illumination** | Non-Illuminated (denoted by the /N or lack of LED code) | | **Operation** | 2-Position or 3-Position Stay-put/Maintained | --- ### 2. Breakdown of the Part Number While nomenclature varies slightly by brand, the string **M2AS1-A223-R2/N** follows this logic: * **M2**: Series identifier (often referring to a 22mm miniature industrial series). * **AS1**: Operator type (e.g., Short lever or Knob selector). * **A**: Action type (Maintained/Stay-put vs Spring Return). * **223**: Circuit logic and physical position (e.g., 90-degree angle, 2-position). * **R2**: Contact block identifier (2 indicate two blocks, R often denotes the mounting style). * **SLASHN (/N)**: Usually indicates a specific revision, "No-brand/Neutral" labeling, or a specific environmental rating (like IP65/NEMA 4X). --- ### 3. Electrical Characteristics These switches are rated for industrial control voltages rather than low-power PCB electronics. * **Rated Insulation Voltage (Ui):** Up to 600V. * **Thermal Current (Ith):** Typically 10A. * **Contact Resistance:** $\le 50m\Omega$ (initial). * **Operating Temperature:** $-25^\circ C$ to $+50^\circ C$. * **Mechanical Life:** 250,000 to 500,000 operations. --- ### 4. Typical Wiring Application The back of the unit features screw terminals. For a 2-position selector: ```mermaid graph LR A[Power Input] --> B(Terminal 1) B -- Switch Turned ON --> C(Terminal 2) C --> D[Load/Motor Starter] ``` ---
