The **M2UDS-16A-R** is a specific type of electronic component, typically categorized as a **DIP (Dual In-line Package) Switch**. These components are widely used on printed circuit boards (PCBs) to manually configure device settings without the need for software programming. --- ### Technical Specifications Below are the general technical parameters associated with this series of switches: | Parameter | Specification | | :--- | :--- | | **Component Type** | DIP Switch / Slide Switch | | **Number of Positions** | 16-Position | | **Actuator Type** | Raised Actuator (Flush/Recessed options may vary) | | **Pitch** | 2.54mm (0.1 inch) Standard Pitch | | **Contact Rating** | 25mA @ 24VDC (Switching) / 100mA @ 50VDC (Non-switching) | | **Insulation Resistance** | 100MΩ Min. at 500VDC | | **Operating Temperature** | -20°C to +85°C | | **Mounting Type** | Through-Hole (THT) | --- ### Key Electronic Features 1. **16-Way Configuration**: The "16A" designation indicates that this part contains 16 individual single-pole, single-throw (SPST) switches housed in a single package. This allows for $2^{16}$ (65,536) different binary combinations. 2. **Gold-Plated Contacts**: Most high-quality DIP switches in this category use gold-plated contacts to ensure high reliability and prevent oxidation over long periods of use. 3. **Mechanical Durability**: Designed for manual manipulation, these parts usually have a mechanical life of approximately 2,000 to 5,000 cycles. 4. **Standard Footprint**: The pins are spaced at a standard 2.54mm pitch, making it compatible with breadboards and standard PCB layouts. --- ### Common Applications The M2UDS-16A-R is commonly found in the following scenarios: * **Address Setting**: Setting unique IDs for devices on a communication bus (e.g., RS-485 or DMX). * **Hardware Configuration**: Enabling or disabling specific hardware features on a motherboard. * **Option Selection**: Choosing between different modes of operation (e.g., baud rate selection) in industrial equipment. ### Schematic Representation In a circuit diagram, each position of the switch is represented as a simple toggle: ```text SW1 (Position 1) Pin 1 o---/ ---o Pin 32 SW2 (Position 2) Pin 2 o---/ ---o Pin 31 ... and so on up to 16 positions. ```
