The **M2AMS2-16B-R** is a specific electronic component, typically categorized as a **DIP (Dual In-line Package) Switch**. These components are widely used on printed circuit boards (PCBs) to manually configure settings or select operating modes for electronic devices. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The part number indicates a specific configuration within a manufacturer's series (often associated with brands like **Diptronics** or similar generic equivalents). | Property | Description | | :--- | :--- | | **Component Type** | SMT (Surface Mount) or Through-Hole DIP Switch | | **Number of Positions** | 2-Position (based on the '2' in the prefix) | | **Actuator Style** | Raised Actuator (Slide type) | | **Contact Material** | Gold-plated (usually) for high reliability | | **Packaging** | Tape & Reel ('R' suffix often denotes Reel packaging) | --- ### 2. Electrical Characteristics These parts are designed for low-power signal switching rather than high-power applications. * **Switching Capacity:** Typically **25mA at 24VDC**. * **Non-Switching Rating:** Typically **100mA at 50VDC**. * **Contact Resistance:** Max 50mΩ initially. * **Insulation Resistance:** 100MΩ minimum at 500VDC. * **Dielectric Strength:** 500VAC for 1 minute. --- ### 3. Physical & Mechanical Parts The construction of the M2AMS2-16B-R involves several specialized materials: 1. **Base and Cover:** High-temperature UL94V-0 thermoplastic (usually PPS or LCP), designed to withstand reflow soldering temperatures. 2. **Actuators:** Thermoplastic Nylon, colored white or red for visibility. 3. **Contacts:** Alloy copper with gold plating over nickel. Gold is used to prevent oxidation over long periods. 4. **Terminals:** Brass with gold or tin plating, designed for stable soldering. --- ### 4. Typical Applications The M2AMS2-16B-R is used in circuits where "Set and Forget" configurations are needed: * **Address Setting:** Setting unique IDs for devices on a communication bus (like RS-485 or DMX). * **Mode Selection:** Toggling between different operating modes (e.g., Test Mode vs. Normal Mode). * **Configuration:** Adjusting frequency, gain, or timeout settings on industrial controllers. --- ### 5. Part Number Breakdown (Example) While nomenclature varies by brand, it generally follows this logic: * **M2A:** Series identifier (often refers to a specific miniature profile). * **MS:** Mechanical Style (Slide type). * **2:** Number of poles/switches in the housing. * **16:** Terminal length or height code. * **B:** Blue color base (common for some manufacturers). * **R:** Tape and Reel packaging for automated pick-and-place assembly.
