The **47DAC-111-R** is a specific part number typically associated with **rotary DIP switches** or specialized **DIP components** often produced by manufacturers like Grayhill or similar electronic component providers. Below is the detailed breakdown of its specifications and electronic characteristics. --- ### 1. General Specifications This component is designed for logic-level switching, commonly used to set addresses or configurations on a PCB without the need for external software interfaces. | Feature | Specification | | :--- | :--- | | **Component Type** | Rotary DIP Switch | | **Output Code** | Binary Coded Decimal (BCD) or Hexadecimal | | **Number of Positions** | 10 or 16 (Standard for this series) | | **Actuator Style** | Flush or Raised Arrow | | **Mounting Type** | Through-hole (THT) or Surface Mount (SMT) | | **RoHS Compliant** | Yes (indicated by the "-R" suffix) | --- ### 2. Electrical Characteristics These parts are engineered for low-power signal switching rather than high-power load handling. * **Contact Rating:** Typically 100mA at 50V DC (non-switching) and 100mA at 5V DC (switching). * **Contact Resistance:** Usually <100mΩ initially. * **Insulation Resistance:** >1000MΩ at 100V DC. * **Dielectric Strength:** 250V AC for 1 minute. --- ### 3. Pin Configuration and Coding The "DAC" designation usually refers to the internal wiring logic. In most 47 series components, the output follows a binary pattern: | Position | Pin 1 (1) | Pin 2 (2) | Pin 3 (4) | Pin 4 (8) | | :--- | :--- | :--- | :--- | :--- | | 0 | OFF | OFF | OFF | OFF | | 1 | **ON** | OFF | OFF | OFF | | 2 | OFF | **ON** | OFF | OFF | | 3 | **ON** | **ON** | OFF | OFF | | ... | ... | ... | ... | ... | --- ### 4. Part Number Breakdown The suffixing follows a standard industrial logic: 1. **47:** Series identifier (Miniature Rotary DIP). 2. **D:** Defines the rotation/actuator type. 3. **AC:** Code type (likely BCD or Real Code). 4. **111:** Dimensional and pin spacing markers. 5. **-R:** Lead-free / RoHS compliant materials. --- ### 5. Common Applications * **Industrial Controls:** Setting Modbus or CAN bus node IDs. * **Telecommunications:** Configuring frequency bands or hardware modes. * **Embedded Systems:** Selecting boot modes or hardware revisions.
