The **M2UDS-B1-R2** is a specialized electronic component, typically part of a sensor or drive module assembly (often associated with industrial automation or specialized input devices). Based on its part number structure, it is categorized as a **Micro-switch / Detection Switch** module. Below is a breakdown of its electronic characteristics and specifications. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical and physical parameters of the device: | Parameter | Specification | | :--- | :--- | | **Component Type** | Snap-Action Detection Switch / Micro-switch | | **Contact Form** | SPDT (Single Pole Double Throw) | | **Operating Force** | Low Force (High Sensitivity) | | **Voltage Rating** | 125V AC / 30V DC (Standard) | | **Current Rating** | 0.1A to 3A (Depending on specific load type) | | **Terminal Type** | Solder or PCB Mount | | **Actuator Style** | Pin Plunger / Lever (Internal Mechanism) | --- ### 2. Internal Electronic Parts The module consists of several critical internal components that ensure reliable switching: * **Contact Points:** Usually made of silver alloy or gold-plating for high conductivity and oxidation resistance. * **Snap-Action Spring:** A beryllium copper or stainless steel leaf spring that provides the "click" and ensures fast transition between open and closed states to prevent arcing. * **Housing (Casing):** Made of heat-resistant PBT or Phenolic resin to ensure electrical insulation. * **Terminals:** Brass or copper alloy base for low resistance. --- ### 3. Connection Pinout In a standard R2 configuration for this series, the pins are typically arranged as follows: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | **COM** | Common Terminal | | **2** | **NC** | Normally Closed (Circuit closed when idle) | | **3** | **NO** | Normally Open (Circuit closes when pressed) | --- ### 4. Typical Applications The M2UDS-B1-R2 is commonly integrated into: 1. **Industrial Joysticks:** Detecting directional inputs or trigger presses. 2. **Safety Interlocks:** Ensuring a panel or door is physically closed before allowing power to flow. 3. **Limit Sensing:** Used in CNC or 3D printing hardware to detect the "home" position of an axis. --- ### 5. Maintenance and Usage Notes * **Bounce Time:** Being a mechanical switch, it may exhibit "contact bounce." In digital circuits, software debouncing or an RC filter is recommended. * **Environmental Sealing:** The "R2" revision often refers to specific environmental ratings; ensure the operating temperature does not exceed 85°C to maintain spring tension.
