The **M8TS-055-R** is a specific electronic component, typically categorized as a **Surface Mount (SMT) Micro Switch** or tactile switch, often used in automotive and industrial control applications. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The M8TS series is known for its durability and small footprint, designed for high-density PCB mounting. | Property | Specification | | :--- | :--- | | **Component Type** | Tactile Switch / Micro Switch | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Actuation Type** | Side Actuated (Right Angle) | | **Operating Force** | Typically 1.6N to 2.5N (Model dependent) | | **Contact Arrangement** | SPST (Single Pole Single Throw) | | **Switch Function** | Momentary (Off-Mom) | --- ### 2. Electrical Characteristics These parts are designed for low-power signal switching rather than high-power load switching. * **Contact Rating:** Usually rated at **50mA @ 12V DC**. * **Contact Resistance:** $\leq 100 \text{ m}\Omega$ (initial). * **Insulation Resistance:** $\geq 100 \text{ M}\Omega$ at 100V DC. * **Dielectric Strength:** 250V AC for 1 minute. * **Bounce Time:** $\leq 10\text{ms}$. --- ### 3. Physical & Environmental Features The "R" suffix in the part number usually indicates **Tape and Reel** packaging for automated pick-and-place assembly. * **Operating Temperature:** -40°C to +85°C (Automotive Grade). * **Durability:** Rated for approximately 50,000 to 100,000 cycles. * **Sealing:** Often features an IP67 rating (dust-tight and water-resistant) depending on the specific housing variant. * **Material:** High-temperature thermoplastic base to withstand reflow soldering temperatures. --- ### 4. Typical Pinout (Internal Logic) Since it is a standard SPST tactile switch, the internal circuit is simple: ```text Terminal 1 (Input) ○-------/ -------○ Terminal 2 (Output) ^ (Push to Close) ``` --- ### 5. Common Applications Due to its right-angle orientation and compact size, the M8TS-055-R is frequently found in: 1. **Automotive:** Steering wheel controls, key fobs, and dashboard buttons. 2. **Consumer Electronics:** Reset buttons on routers or side buttons on handheld devices. 3. **Industrial:** Interface panels and limit detection in small robotics.
