The **AOGW301-R** is a specific part number typically associated with industrial control components, specifically within the **IDEC TW series** of 22mm pushbuttons. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. General Specifications The AOGW301-R is a **22mm Mushroom Head Pushbutton**. It is designed for industrial panels where durability and reliability are paramount. | Feature | Specification | | :--- | :--- | | **Series** | IDEC TW Series | | **Operator Type** | Mushroom Head (ø40mm) | | **Function** | Momentary (Spring Return) | | **Contact Configuration** | 1NC (Normally Closed) | | **Mounting Hole** | 22mm | | **Color** | Red (R) | --- ### 2. Contact Block Characteristics The "electronic" heart of the device is the contact block attached to the back of the operator. * **Contact Rating:** Typically rated for heavy-duty industrial use. * **AC Load:** Up to 600V. * **DC Load:** Up to 250V. * **Thermal Current (Ith):** 10A. * **Contact Material:** Silver contacts (standard for high conductivity and oxidation resistance). * **Terminal Type:** Screw terminals with "HW-U" type safety-levers. --- ### 3. Part Number Breakdown To understand the specific electronic behavior, we can deconstruct the code: | Segment | Meaning | Description | | :--- | :--- | :--- | | **AO** | Operator Type | Mushroom Head Pushbutton | | **G** | Series | TW Series (Chrome Plated Zinc Locking Ring) | | **W** | Terminal | Standard Type | | **3** | Function | Momentary Action (Springs back when released) | | **01** | Contact Arrangement | 0 NO (Normally Open) / 1 NC (Normally Closed) | | **-R** | Color | Red | --- ### 4. Environmental & Electrical Durability This part is engineered to withstand harsh environments: * **Ingress Protection:** IP65 (Water-resistant and dust-tight when mounted in an appropriate enclosure). * **Mechanical Life:** Approximately 5,000,000 operations. * **Electrical Life:** Approximately 500,000 operations (at full load). * **Insulation Resistance:** 100 MΩ minimum (500V DC megger). --- ### 5. Typical Wiring Diagram The "01" suffix indicates a single Normally Closed contact. In a logic circuit, it is represented as follows: ```text (Input) L1 ---- [ | ] ---- (Output) Load (NC) ``` *When the button is pressed, the circuit is broken (the load loses power).* ---
