The **2PE-16-R** typically refers to a specific type of **Rotary DIP Switch** or a coded rotary selector component. These parts are commonly used in industrial electronics, telecommunications, and circuit prototyping for manual configuration. --- ### 1. Key Technical Specifications Based on standard industry naming conventions for this series (often associated with brands like ECE or generic industrial manufacturers), here are the primary specifications: | Feature | Specification | | :--- | :--- | | **Component Type** | Rotary DIP Switch | | **Number of Positions** | 16 (Hexadecimal) | | **Output Code** | Binary Coded Hexadecimal (BCH) | | **Mounting Type** | Through-hole (THT) or PCB Mount | | **Contact Rating** | 100mA, 5V DC (Switching) / 250mA, 50V DC (Non-switching) | | **Actuator Style** | Arrow / Recessed (Usually Requires Screwdriver) | --- ### 2. Functional Details * **The "16" in the Name:** This indicates the switch has 16 distinct positions (0 through 9 and A through F). * **Binary Coding:** As you rotate the dial, the internal contacts bridge four output pins in combinations representing binary values (1, 2, 4, 8). * **"R" Suffix:** Often denotes **Real Code** (as opposed to Complement Code). In Real Code, position '1' closes the '1' pin circuit. In Complement Code, it would open it. * **Size:** These are usually compact parts (approx. 10mm x 10mm) designed to save space on a Printed Circuit Board (PCB). --- ### 3. Pin Configuration (Common Standard) For a 16-position BCH switch like the 2PE-16-R, the pinout usually consists of 6 pins: 1. **C (Common):** Usually two pins (internally connected) to provide the input signal. 2. **1 (2^0):** Least Significant Bit (LSB). 3. **2 (2^1):** Bit 2. 4. **4 (2^2):** Bit 3. 5. **8 (2^3):** Most Significant Bit (MSB). ### 4. Typical Applications * **Address Setting:** Used in RS-485 or DMX networks to set a specific device ID (0-255 using two switches). * **Mode Selection:** Choosing firmware operational modes without needing a screen or menu system. * **Configuration:** Adjusting frequency channels in RF modules or industrial timers. --- ### 5. Truth Table (Real Code) | Position | 1 (2^0) | 2 (2^1) | 4 (2^2) | 8 (2^3) | | :--- | :---: | :---: | :---: | :---: | | 0 | Off | Off | Off | Off | | 1 | **ON** | Off | Off | Off | | 5 | **ON** | Off | **ON** | Off | | F (15) | **ON** | **ON** | **ON** | **ON** |
