The **M2UDS2-06-R/Q** refers to a high-quality, professional-grade **Rotary DIP Switch** (Dual In-line Package). These components are commonly used in industrial controls and telecommunications to manually set binary or hexadecimal values on a circuit board. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | Rotary DIP Switch | | **Number of Positions** | 16 Positions (Hexadecimal) | | **Output Code** | Real Binary Coded Decimal (BCD) / Hex | | **Mounting Type** | Through-Hole (THT) | | **Actuator Style** | Arrow/Screwdriver Slotted (Flush) | | **Voltage Rating** | 24V DC (Switching) / 50V DC (Non-switching) | | **Current Rating** | 100mA (Switching) / 400mA (Steady state) | --- ### 2. Physical Design and Construction The "M2UDS" series is typically characterized by its robust internal mechanics designed for high reliability. * **Housing:** Usually made of heat-resistant plastic (Polyamide) to withstand wave soldering. * **Contacts:** Gold-plated contacts are standard to prevent oxidation and ensure low contact resistance over the component's lifespan. * **Sealing:** These parts are often "process sealed" (indicated by the 'R' or 'Q' suffix variations), meaning they have an O-ring or potting that allows them to be washed after soldering without damaging the internals. --- ### 3. Electronic Functionality This part functions as a digital encoder. When you rotate the dial to a specific number (0-15), the internal metallic wipers connect the common pin to a specific combination of four output pins (1, 2, 4, and 8). **Logic Table Example:** * **Position 0:** All output pins are Open. * **Position 1:** Pin 1 is Closed (High). * **Position 7:** Pins 1, 2, and 4 are Closed (1+2+4=7). * **Position F (15):** All output pins (1, 2, 4, 8) are Closed. --- ### 4. Common Applications * **Address Setting:** Setting unique IDs for devices on a BUS (like RS-485 or CAN bus). * **Mode Selection:** Choosing operational modes for industrial PLCs. * **Configuration:** Adjusting hardware parameters without needing a digital interface or software tool. ---
