The **M6SXAT-2-R** is a specific surface-mount electronic component, typically categorized as a **Micro-Miniature Tactile Switch**. These switches are designed for low-power signal switching in compact consumer electronics and industrial interfaces. --- ### 1. Key Technical Specifications Below are the typical electrical and mechanical parameters for this series: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Tactile (Momentary) | | **Mounting Type** | Surface Mount (SMT/SMD) | | **Actuation Force** | 1.6N to 2.5N (Typical) | | **Voltage Rating** | 12V DC | | **Current Rating** | 50mA | | **Contact Resistance** | 100mΩ Max | | **Operating Life** | 100,000 Cycles | --- ### 2. Component Structure and Materials The "M6SX" series usually follows a standard construction profile designed for durability and automated assembly: * **Actuator:** Usually a round or square plunger made of high-temperature plastic (LCP) to withstand reflow soldering. * **Contact Dome:** A stainless steel or copper alloy dome that provides the "click" feedback (tactile sensation) and completes the circuit. * **Terminals:** Silver-plated or Gold-plated leads for high conductivity and oxidation resistance. * **Base/Housing:** Heat-resistant thermoplastic. --- ### 3. Part Number Breakdown (Typical) While naming conventions vary slightly by manufacturer (such as Mitsumi or similar clones), the suffix generally indicates: * **M6SX:** The series/form factor (often 6x6mm or smaller micro-footprint). * **AT:** Actuator Type (standard or raised height). * **2:** Specific force or height variation. * **-R:** **Tape and Reel** packaging (indicating it is ready for automated Pick-and-Place assembly). --- ### 4. Common Applications Due to its small footprint and reliable tactile feedback, the M6SXAT-2-R is found in: 1. **Consumer Electronics:** Power buttons on cameras, volume buttons on smartphones. 2. **Wearables:** Smartwatches and fitness trackers. 3. **Industrial:** Reset switches on PCB boards or membrane keypad interfaces. 4. **Automotive:** Interior control panels and key fobs. --- ### 5. Footprint and Soldering * **SMD Pads:** This part requires specific solder pad geometry to ensure mechanical stability, as it will be subjected to physical pressure. * **Reflow Profile:** Designed to withstand JEDEC standard lead-free reflow temperatures (approx. 260°C).
