The **M2UDS2-B6-R** is a specific part number typically associated with an industrial **Selector Switch** or a **Push Button** assembly, often manufactured by brands like **IDEC** or similar industrial control component makers. Below is a breakdown of its electronic and mechanical characteristics: ## Product Overview: M2UDS2-B6-R This component is part of a modular series designed for control panels, machinery, and automation systems. It serves as a human-machine interface (HMI) to trigger electrical circuits. --- ### Technical Specifications | Feature | Description | | :--- | :--- | | **Component Type** | Selector Switch / Control Unit | | **Bezel Shape** | Round (Standard Industrial) | | **Operator Type** | Knob-type Selector | | **Positions** | 2-Position (Maintain or Spring Return depending on internal cam) | | **Color** | Red (indicated by the **-R** suffix) | | **Mounting Hole** | 22mm (Standard industrial diameter) | | **Contact Block** | Typically supports NO (Normally Open) or NC (Normally Closed) modules | --- ### Key Electronic & Mechanical Parts #### 1. The Operator (Head) The "B6" in the part number usually refers to the physical shape and operation of the knob. * **Material:** High-grade plastic or die-cast metal (depending on the specific series). * **Rotation:** Features a defined "throw" angle (usually 90 degrees) to switch between states. #### 2. The Mounting Collar This is the bridge between the operator (outside the panel) and the contact blocks (inside the panel). * It ensures a tight seal, often rated **IP65 or NEMA 4X**, protecting the electronics from dust and water. #### 3. Contact Blocks (The Electrical Interface) While the M2UDS2 refers to the operator, it actuates "Contact Blocks" attached to the back. * **Current Rating:** Usually rated for 6A to 10A at 120/240VAC. * **Logic:** When the knob is turned, a physical cam pushes a plunger on the contact block, opening or closing the electrical circuit. #### 4. The Suffix Decoding * **M2:** Often denotes the series (22mm Miniature/Standard). * **U:** Universal or specific mounting style. * **B6:** The specific mechanical action (e.g., 2-position maintained). * **R:** Color (Red). --- ### Typical Applications * **Emergency Stop/Safety Logic:** Red selectors are often used for "Off/On" safety locks. * **Mode Selection:** Switching a machine between "Manual" and "Auto" modes. * **Power Distribution:** Activating a primary contactor for industrial power. ---
