The part number **10RS-5D-R6-R/C02** refers to a specific configuration of a **rotary DIP switch**, likely manufactured by companies like **Copal Electronics (Nidec)** or similar specialized switch manufacturers. These components are used to set binary or hexadecimal values manually on a circuit board. --- ### Component Breakdown The alphanumeric string defines the physical and electrical characteristics of the switch: | Segment | Meaning | Description | | :--- | :--- | :--- | | **10** | Number of Positions | 10-position (Decimal/BCD) ranging from 0 to 9. | | **RS** | Series/Type | Rotary Selector Switch, typically Surface Mount (SMD). | | **5D** | Actuator Style | Refers to the height and shape of the knob/shaft (e.g., Extended shaft or flush). | | **R6** | Terminal Layout | Standard pin configuration or "Gull-wing" lead shape for soldering. | | **R/C02** | Packaging/Specs | Indicates Tape & Reel (R) packaging and a specific factory revision (C02). | --- ### Technical Specifications Below are the typical electrical and mechanical ratings for this class of component: | Feature | Specification | | :--- | :--- | | **Switch Logic** | BCD (Binary Coded Decimal) | | **Voltage Rating** | 50V DC (Non-switching), 5V DC (Switching) | | **Current Rating** | 100mA (Non-switching), 100mA (Switching) | | **Contact Resistance** | < 100 mΩ | | **Operating Temp** | -40°C to +85°C | | **Rotational Life** | 10,000 steps minimum | --- ### Common Applications 1. **Address Setting:** Used in industrial automation (RS-485 or CAN bus) to set the unique ID of a device on a network. 2. **Configuration:** Setting operation modes on a PCB without needing a digital interface. 3. **Hardware Logic:** Pre-setting counter values or timers in embedded systems. --- ### Circuit Symbol & Logic In a 10-position BCD switch, the pins are mapped as follows: - **Common (C):** The input voltage/ground. - **1, 2, 4, 8:** The output pins representing the binary weight. ```text Position | Pin 8 | Pin 4 | Pin 2 | Pin 1 ---------------------------------------- 0 | OFF | OFF | OFF | OFF 1 | OFF | OFF | OFF | ON 5 | OFF | ON | OFF | ON 9 | ON | OFF | OFF | ON ```
