The part number **2RT-16-R/B** typically refers to a **Rotary DIP Switch**. These components are widely used in electronics for setting binary configurations, addressing, or mode selection on a printed circuit board (PCB). --- ## 1. Component Specifications Below are the general technical characteristics for this series of rotary switches: | Feature | Specification | | :--- | :--- | | **Switch Type** | Rotary DIP Switch | | **Number of Positions** | 16 (Hexadecimal) | | **Output Code** | Real Code (Binary Coded Hexadecimal) | | **Actuator Style** | Arrow / Flush / Raised (Model dependent) | | **Pitch** | 2.54mm (Standard Breadboard/PCB spacing) | | **Voltage Rating** | 24V DC (Switching), 50V DC (Non-switching) | | **Current Rating** | 100mA | | **Mounting Type** | Through-Hole (THT) | --- ## 2. Part Number Breakdown While nomenclature can vary slightly by manufacturer (such as *Redsunt* or *ECE*), the code generally breaks down as follows: * **2RT**: Series identifier for 10mm or 7mm square rotary switches. * **16**: Indicates the number of positions (0 through 15/F). * **R**: Usually denotes **Real Code** (as opposed to Complement Code). * **B**: Often refers to the packaging or terminal type (e.g., Tube or Bulk packaging, or "Blue" housing depending on the brand). --- ## 3. Truth Table (Real Code) Since this is a 16-position switch, it uses 4 output pins (plus a common pin) to represent binary values. | Position | Binary (1-2-4-8) | Hex Equivalent | | :--- | :--- | :--- | | 0 | 0000 | 0 | | 1 | 1000 | 1 | | ... | ... | ... | | 9 | 1001 | 9 | | 10 | 0101 | A | | 15 | 1111 | F | --- ## 4. Common Applications * **Address Settings:** Setting the ID for devices on a communication bus (like RS-485 or CAN). * **Mode Selection:** Choosing operating modes in industrial controllers or IoT gateways. * **Configuration:** Adjusting hardware parameters without needing a digital interface or software. ---
