The **RBS-55-R** is an electronic component primarily classified as a **Rotary DIP Switch**. These devices are used on printed circuit boards (PCBs) to allow manual configuration of hardware settings, such as device addresses or mode selections. ### 1. Key Technical Specifications Below are the general specifications typical for the RBS-55 series: | Feature | Specification | | :--- | :--- | | **Type** | Rotary DIP Switch | | **Positions** | 10 Positions (Decimal) or 16 Positions (Hexadecimal) | | **Output Code** | Real Code (Binary Coded) | | **Mounting Type** | Through-hole (R-suffix often indicates specific orientation/packaging) | | **Contact Rating** | 100mA @ 5V DC (Switching) / 100mA @ 50V DC (Non-switching) | | **Operating Temperature** | -25°C to +70°C | --- ### 2. Physical Characteristics The RBS-55-R features a compact, square body designed to save space on a PCB. * **Actuator Style:** Usually features a "Flat" or "Arrow" type top that can be rotated using a small screwdriver. * **Sealing:** Most models are sealed to withstand wave soldering and board washing processes (often rated IP67). * **R-Suffix Meaning:** In many manufacturer nomenclatures (like Copal or similar brands), the **"R"** indicates the packaging type (e.g., **Tape & Reel**) or a specific **Right-Angle** pin orientation. --- ### 3. Electronic Functionality The switch operates by converting the mechanical position of the dial into a **BCD (Binary Coded Decimal)** or **Hexadecimal** electrical output. #### Common Pinout Configuration: 1. **Common (C):** The input terminal. 2. **Bit 1 ($2^0$):** Lowest significant bit. 3. **Bit 2 ($2^1$):** 4. **Bit 4 ($2^2$):** 5. **Bit 8 ($2^3$):** Highest significant bit. --- ### 4. Applications * **Industrial Automation:** Setting unique IDs for sensors on a bus. * **Telecommunications:** Configuring frequency bands or internal logic. * **Embedded Systems:** Hard-coding mode selections (e.g., "Debug Mode" vs. "Production Mode"). ---
