The **M2AS1-A211-R/CE** is a specific industrial-grade control component, typically identified as a **Selector Switch** or a **Control Switch** from the M2AS series (often associated with brands like Tend or similar industrial automation manufacturers). Below is a breakdown of its electronic and mechanical specifications. --- ### 1. Part Number Breakdown While naming conventions vary slightly by manufacturer, here is the typical functional mapping for this part number: | Segment | Description | Specific Detail | | :--- | :--- | :--- | | **M2AS** | Series | 22mm Diameter Industrial Control Series | | **1** | Type | Standard Lever/Short Handle Selector | | **A** | Operation | Maintained (Stay-put) position | | **2** | Positions | 2-Position switch (90° throw) | | **11** | Contact Block | 1 NO (Normally Open) + 1 NC (Normally Closed) | | **R/CE** | Color/Cert | Red Handle / CE Certified (European Standards) | --- ### 2. Electrical Specifications These components are designed for pilot duty in control circuits rather than powering heavy loads directly. * **Rated Insulation Voltage (Ui):** Typically 600V. * **Thermal Current (Ith):** 10A. * **Contact Resistance:** $\le$ 50m$\Omega$. * **Electrical Life:** 500,000 operations (minimum). * **Standard Ratings:** * **AC-15:** 240V / 3A * **DC-13:** 125V / 0.55A --- ### 3. Physical & Environmental Features * **Mounting Diameter:** 22mm (standard industrial cutout). * **Protection Rating:** IP65 (Dust-tight and protected against water jets). * **Operating Temperature:** -25°C to +70°C. * **Contact Blocks:** Modular design; the "11" designation implies one NO and one NC block are pre-attached to the actuator base. --- ### 4. Connection Diagram Example The switch operates by rotating the lever to bridge or break the internal contacts. ```text Position Left (0°): - NC Contact: Closed (Current flows) - NO Contact: Open (No flow) Position Right (90°): - NC Contact: Open (No flow) - NO Contact: Closed (Current flows) ``` --- ### 5. Application Areas This specific part is used in: * **Power Distribution:** Switching between manual and automatic modes. * **Safety Circuits:** As a selector for machine states. * **Control Panels:** Integrated into PLC (Programmable Logic Controller) inputs to trigger specific logic rungs.
