The **M2ADS-A22-R2** is a specific industrial control component, typically identified as a **Pushbutton Switch** (often associated with brands like Omron or similar industrial automation suppliers). It is designed for panel mounting to control electrical circuits manually. --- ### 1. Technical Specifications The following table outlines the general electronic and physical characteristics of this part: | Feature | Specification | | :--- | :--- | | **Type** | Non-lighted Pushbutton | | **Actuator Shape** | Mushroom Head (Large surface area) | | **Mounting Diameter** | 22 mm | | **Contact Configuration** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Switch Operation** | Momentary (Spring return) | | **Color** | Red (R2 suffix usually denotes color and style) | | **Protection Rating** | IP65/IP66 (Water and dust resistant) | --- ### 2. Key Electronic Components The device is modular, consisting of three primary electronic/mechanical sections: #### A. The Operator (Actuator) The "Mushroom" head is the user interface. Its physical design is ergonomic, allowing for quick activation (often used as a non-locking stop button or a general-purpose command input). #### B. The Mounting Latches This mechanical part secures the operator to the control panel. In the R2 series, this is usually a plastic or metal bracket that holds the contact blocks in place behind the panel. #### C. The Contact Block This is the core electronic element. * **Terminals:** Usually screw-type terminals for securing 14–22 AWG wiring. * **Conductivity:** Uses silver or gold-plated contacts to ensure low electrical resistance. * **Action:** When pressed, the internal bridge completes the circuit between the two terminals. --- ### 3. Application Use Cases Due to its robust design, the M2ADS-A22-R2 is commonly found in: 1. **Industrial Control Panels:** To start or stop motors (when wired to a PLC). 2. **Safety Signaling:** The red mushroom head makes it highly visible for urgent manual inputs. 3. **Harsh Environments:** The IP rating ensures it functions in factories with high humidity or dust. ---
