The **AOFW411-R** is a specific part number typically associated with industrial automation components, specifically within the **IDEC TW series** of 22mm pushbuttons. This particular model is a non-illuminated, momentary pushbutton switch designed for control panels. --- ### Technical Specifications The following table breaks down the electronic and mechanical characteristics of the AOFW411-R: | Feature | Specification | | :--- | :--- | | **Series** | IDEC TW Series | | **Mounting Hole** | 22mm | | **Operator Shape** | Extended Mushroom Head (40mm) | | **Operation Type** | Momentary (Spring Return) | | **Contact Configuration** | 1NO (Normally Open) + 1NC (Normally Closed) | | **Contact Material** | Silver contacts | | **Rated Voltage** | 600V (Insulation) | | **Rated Current** | 10A (Thermal) | | **Color** | Red (indicated by the "-R" suffix) | --- ### Component Breakdown #### 1. Contact Blocks (1NO-1NC) The "411" in the part number signifies the contact arrangement. It contains one set of contacts that are open when at rest (NO) and one set that are closed (NC). This allows for dual-purpose logic: * **NO:** Closes a circuit to start a process. * **NC:** Opens a circuit to stop a process or provide an interlock. #### 2. The Operator (Mushroom Head) The "AOFW" designation refers to the physical style. This model features a **40mm Extended Mushroom Head**. This is preferred in industrial environments where the operator might be wearing gloves or needs to actuate the switch quickly without precision. #### 3. Protection Rating These parts are engineered for harsh environments. They typically carry the following ratings: * **IP65:** Dust-tight and protected against water jets. * **NEMA 4X:** Corrosion-resistant and suitable for outdoor or wash-down areas. --- ### Common Applications The AOFW411-R is commonly found in: * **Industrial Control Panels:** As a manual override or cycle start/stop. * **Safety Interlocks:** Used in conjunction with safety relays (though it is not a "Latched Emergency Stop" since it is momentary). * **Machinery UI:** Standard interface for CNC machines, conveyors, and packaging equipment.
