The **RBS-5E-R** is an industrial-grade, ultra-compact **Rotary DIP Switch** manufactured by companies like ECE (Excel Cell Electronic). It is primarily used on printed circuit boards (PCBs) to set configurations, addresses, or modes without needing external software. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Switch Type** | Rotary DIP Switch | | **Number of Positions** | 10 Positions (0-9) | | **Output Code** | BCD (Binary Coded Decimal) | | **Actuator Type** | Shaft Type (Rotatable handle) | | **Mounting Type** | Through-Hole (THT) | | **Pitch** | 2.54mm (Standard) | | **Contact Rating** | 100mA, 50V DC (Steady), 25mA, 24V DC (Switching) | --- ### 2. Electronic Functionality The "5E" in the part number typically denotes the **BCD Output**. This means the switch translates the physical position of the dial into a 4-bit binary signal. #### BCD Truth Table (Logic) The switch has one common pin (C) and four output pins (1, 2, 4, 8). | Position | Pin 1 | Pin 2 | Pin 4 | Pin 8 | | :--- | :--- | :--- | :--- | :--- | | 0 | OFF | OFF | OFF | OFF | | 1 | **ON** | OFF | OFF | OFF | | 3 | **ON** | **ON** | OFF | OFF | | 5 | **ON** | OFF | **ON** | OFF | | 9 | **ON** | OFF | OFF | **ON** | --- ### 3. Material and Build Features * **Gold-Plated Contacts:** Ensures high reliability and prevents oxidation over long periods of use. * **Sealed Construction:** The "R" suffix often indicates a **Tape & Reel** packaging or a specific **Washable/Sealed** design that allows the board to be cleaned after soldering without damaging the internal contacts. * **Heat Resistance:** Designed to withstand wave soldering temperatures (typically up to 260°C). --- ### 4. Common Applications * **Industrial Automation:** Setting unique Modbus or CAN bus slave IDs. * **Telecommunications:** Configuring frequency bands or hardware modes. * **Home Automation:** Pairing codes for security systems. * **Prototyping:** Manually toggling logic states during hardware debugging. ---
