The **47LPQ-61R-R** is a specific part number belonging to a series of high-performance **rotary DIP switches** (often associated with Grayhill's 47L series). These components are used to manually set binary or hexadecimal values on a circuit board by rotating a dial. --- ## 1. Technical Specifications Below are the typical specifications for this component class: | Feature | Specification | | :--- | :--- | | **Component Type** | Rotary DIP Switch | | **Number of Positions** | 16 (Hexadecimal) | | **Output Code** | BCD (Binary Coded Decimal) or Hexadecimal | | **Actuator Style** | Flush or Raised (Arrow/Screwdriver slot) | | **Mounting Type** | Through-hole (PCB) | | **Terminal Finish** | Gold over Nickel (R-R designation often implies RoHS compliance) | | **Operating Force** | 400 gf-cm (Approximate) | --- ## 2. Key Features * **Space-Saving Design:** The "LPQ" (Low Profile) designation indicates that the component has a minimal footprint and height, making it ideal for compact electronic enclosures. * **Durability:** These switches are designed for "set and forget" applications but are rated for thousands of actuations. * **Environmental Sealing:** Most models in this series are sealed to withstand wave soldering and cleaning processes without contamination. --- ## 3. Internal Logic Table (Hexadecimal) Since it is a 16-position switch, it translates the physical position of the dial into a 4-bit binary output across four pins: | Position | 1 (2⁰) | 2 (2¹) | 4 (2²) | 8 (2³) | | :--- | :--- | :--- | :--- | :--- | | 0 | OFF | OFF | OFF | OFF | | 1 | **ON** | OFF | OFF | OFF | | ... | ... | ... | ... | ... | | F (15) | **ON** | **ON** | **ON** | **ON** | --- ## 4. Common Applications * **Address Setting:** Used in industrial networking (Modbus/CANbus) to manually set the unique ID of a device. * **Configuration:** Selecting operational modes on a motherboard or controller without needing software tools. * **Testing:** Hardware debugging where specific logic states need to be forced manually. ---
