The **WAC-A5AD-R** is a specific electronic component, typically categorized as a **DIP Switch** (Dual In-line Package Switch) or a specialized connector component, often manufactured by brands like **Walsin** or specialized industrial electronics suppliers. Below is a breakdown of the electronic characteristics and technical aspects typically associated with this part number. --- ### 1. General Specifications The WAC-A5AD-R is designed for PCB (Printed Circuit Board) mounting. Its primary function is to manually open or close an electrical circuit or to configure settings on a hardware device. | Parameter | Typical Value | | :--- | :--- | | **Component Type** | DIP Switch / Slide Switch | | **Mounting Type** | Through-hole (THT) | | **Number of Positions** | Variable (often 5-position based on "A5") | | **Actuator Type** | Raised or Recessed Slide | | **Contact Plating** | Gold or Tin-plated | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Electronic Characteristics To ensure the component operates correctly within a circuit, the following electrical ratings are standard for this series: * **Switching Capacity:** Usually rated around **25mA at 24V DC**. * **Non-Switching Rating:** Can handle up to **100mA at 50V DC**. * **Contact Resistance:** Typically **50mΩ maximum** (initial). * **Insulation Resistance:** Minimum of **100MΩ at 500V DC**. * **Dielectric Strength:** Capable of withstanding **500V AC** for one minute. --- ### 3. Physical & Material Composition The "R" at the end of the part number usually signifies **RoHS Compliance**, meaning the part is free from hazardous substances like lead or mercury. 1. **Housing:** High-temperature UL94V-0 rated thermoplastic (usually black or blue). 2. **Actuators:** Thermoplastic (white). 3. **Base:** Sealed with epoxy (optional) to prevent solder flux from entering the contacts during manufacturing. 4. **Terminals:** Copper alloy with gold plating over nickel to prevent oxidation and ensure long-term conductivity. --- ### 4. Common Applications This part is commonly found in industrial and consumer electronics where user-defined configuration is required without software: * **Modems/Routers:** Setting frequency bands or device IDs. * **Industrial Controllers:** Addressing nodes in a PLC network. * **Garage Door Openers:** Programming security codes. * **PC Motherboards:** Legacy hardware configuration (IRQ/Voltage settings). ---
