The **M2RS-06-R** is a specific electronic component, typically categorized as a **DIP switch** or a **Rotary Coded Switch** (depending on the specific manufacturer series, though the "M2RS" prefix is commonly associated with high-quality miniature rotary selector switches). Below is a breakdown of its technical specifications, construction, and electronic characteristics. --- ### 1. Technical Specifications This table summarizes the general electrical and mechanical characteristics of the M2RS-06-R. | Parameter | Specification | | :--- | :--- | | **Component Type** | Rotary Coded Switch | | **Positions** | 6 Positions (indicated by "06") | | **Mounting Type** | Through-hole (PCB) | | **Contact Rating** | 100mA at 5V DC (Switching) / 100mA at 50V DC (Non-switching) | | **Contact Resistance** | 100 mΩ maximum | | **Insulation Resistance** | 100 MΩ minimum at 250V DC | | **Operating Temperature** | -25°C to +70°C | | **Actuator Style** | Recessed / Flush (Screwdriver slot) | --- ### 2. Electronic Functionality The "R" in the suffix usually denotes **Real Code** (Binary Coded Decimal or a specific sequence), while the "06" indicates the number of selectable states. * **Binary Coding:** As the dial is turned, it bridges internal metallic traces to create a specific output pattern on the pins. * **Logic Interfacing:** It is frequently used to set addresses or configurations for microcontrollers. For example, a 6-position switch can define up to 6 unique logic states using a combination of high/low signals. * **Wiping Contact:** The internal mechanism uses a "wiping" contact system that self-cleans the gold-plated surfaces to ensure low resistance over thousands of cycles. --- ### 3. Physical Construction The M2RS series is designed for durability and space-saving on a Printed Circuit Board (PCB). 1. **Housing:** Usually made of high-temperature liquid crystal polymer (LCP) or PBT plastic to withstand wave soldering. 2. **Pins:** Arranged in a standard pitch (usually 2.54mm or similar) for easy integration into breadboards or standard PCBs. 3. **Sealing:** Many versions are "process sealed" with an O-ring or tape, allowing them to be washed after soldering without damaging the internal contacts. --- ### 4. Common Applications * **Industrial Controls:** Setting Modbus or CAN bus node IDs. * **Consumer Electronics:** Selecting modes of operation (e.g., timer intervals). * **Telecommunications:** Configuring hardware presets without needing a digital interface.
