The **WADS-16B2-R/E** is a specific electronic component typically categorized as a **DIP (Dual In-line Package) Switch**. These components are widely used in industrial electronics, telecommunications, and consumer devices to set configuration parameters on a circuit board without needing to change software or use external tools. --- ### Technical Specifications Below are the general characteristics associated with the WADS series 16-position switches: | Feature | Specification Details | | :--- | :--- | | **Component Type** | Rotary DIP Switch | | **Positions** | 16 Positions (Hexadecimal) | | **Output Code** | Binary Coded Hexadecimal (Real Code) | | **Mounting Type** | Through-Hole / PC Pin | | **Actuator Type** | Recessed (R) / Extended (E) Shaft | | **Contact Rating** | 100mA at 5V DC (Switching), 100mA at 50V DC (Non-switching) | | **Operating Temp** | -25°C to +70°C | --- ### Key Electronic Components & Internal Design #### 1. The Rotor and Contacts The internal mechanism consists of a rotating disc (the rotor) with conductive paths. As the user turns the dial to one of the 16 positions (0-9, A-F), the rotor bridges specific pins to the "Common" pin. #### 2. Coding Logic (Binary Coded Hexadecimal) The "16B" designation indicates it is a 16-way switch. It converts the physical position into a 4-bit binary output. * **Position 0:** All output pins are Open. * **Position 7:** Pins 1, 2, and 4 are Closed (Binary 0111). * **Position F (15):** Pins 1, 2, 4, and 8 are Closed (Binary 1111). #### 3. Terminal Layout The unit typically features 5 or 6 pins: * **Common (C):** The input voltage source. * **Bit 1 (1):** Least Significant Bit (LSB). * **Bit 2 (2):** * **Bit 4 (4):** * **Bit 8 (8):** Most Significant Bit (MSB). --- ### Suffix Meanings * **R/E:** This usually refers to the **Actuator style**. * **R:** Recessed (requires a screwdriver to turn, preventing accidental changes). * **E:** Extended (has a small knob or shaft for manual turning by hand). --- ### Typical Applications * **Address Setting:** Setting the unique ID for a device on a RS-485 or CAN bus network. * **Mode Selection:** Choosing between different operational modes in industrial controllers (PLCs). * **Configuration:** Adjusting hardware-level settings on computer motherboards or peripheral cards.
