The **5220-DS02-R** is a specific electronic component typically identified as a **tactile switch** (or tact switch) commonly manufactured by companies like **PUI Audio** or similar electronic hardware suppliers. It is designed to provide physical feedback to a user when pressed. --- ### 1. General Specifications Based on standard industry data for this part number, here are the technical characteristics: | Property | Specification | | :--- | :--- | | **Component Type** | Tactile Switch | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Actuation Force** | Usually 160gf to 260gf (Grams-force) | | **Contact Rating** | 50mA @ 12VDC (Typical) | | **Operating Life** | ~100,000 to 500,000 cycles | | **Contact Material** | Silver Plated | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Physical Construction The part is engineered for automated assembly and durability: * **Seal/Protection:** The "DS" in the suffix often indicates a specific seal type or dust protection, making it suitable for environments where particles might interfere with electrical contacts. * **Actuator:** Usually a short travel button made of high-temperature plastic (LCP or Nylon) to withstand reflow soldering. * **Terminals:** Gull-wing or J-bend leads designed for PCB surface mounting. --- ### 3. Key Applications These switches are found in various consumer and industrial electronics: 1. **Consumer Electronics:** Power buttons on cameras, volume controls on Bluetooth speakers, and interface buttons on smart home devices. 2. **Medical Devices:** Handheld diagnostic tools requiring tactile user confirmation. 3. **Industrial Controls:** Reset buttons on PCBs or configuration switches inside control panels. --- ### 4. Interpretation of the Part Suffixes * **5220:** The base series/model number defining the footprint and height. * **DS:** Often refers to **D**ust-proof or **S**ealed characteristics. * **02:** Can represent the specific height of the actuator (e.g., 2.0mm or 2.5mm). * **-R:** Strictly denotes **RoHS Compliance** (Lead-free) or **Tape & Reel** packaging for automated pick-and-place machines. ---
