The **M2UDS-40-R** is a specific electronic component, typically part of a connector series or a specialized industrial interface. Based on its nomenclature, it is most commonly associated with **40-pin micro-connectors** or **high-density board-to-board connectors** used in automated systems and PLCs. Below is a detailed breakdown of its electronic characteristics and specifications. --- ## 1. Technical Specifications The "40" in the part number usually denotes the pin count, while the "R" often signifies a Right-Angle orientation or a Reel-packaged version. | Feature | Specification (Typical) | | :--- | :--- | | **Pin Count** | 40 Pins | | **Pitch** | 2.54mm or 2.0mm (standard) | | **Configuration** | Double Row (20x2) | | **Mounting Type** | Through-Hole or SMT (depending on suffix) | | **Current Rating** | 1A to 3A per contact | | **Voltage Rating** | 250V AC/DC | | **Operating Temp** | -40°C to +105°C | --- ## 2. Structural Components Anatomy of the M2UDS-40-R connector: ### A. Contact Material * **Base:** Phosphor Bronze or Brass for high conductivity and elasticity. * **Plating:** Gold flash or Tin over Nickel. Gold is used on the contact points to prevent oxidation and ensure low contact resistance over time. ### B. Insulator Body * **Material:** PBT (Polybutylene Terephthalate) or High-Temp Nylon (LCP). * **Flammability:** Usually rated **UL94V-0**, meaning it is self-extinguishing in case of a fire. ### C. Mechanical Housing * Often includes a "shroud" or a polarized keying mechanism to prevent incorrect insertion (mating error). --- ## 3. Circuit Application In electronic systems, the M2UDS-40-R serves as the physical interface for several signal types: 1. **Data Bus Interconnects:** Connecting a main logic board to a peripheral I/O board. 2. **Flat Ribbon Cable (IDC) Interface:** Often used as the header for 40-pin ribbon cables. 3. **PLC Modules:** Frequently found in industrial automation equipment for modular signal routing. --- ## 4. Part Number Breakdown (Generalized) | Prefix/Suffix | Meaning | | :--- | :--- | | **M2UDS** | Series identifier (Micro-Universal Dual Slot/Socket) | | **40** | Number of total positions | | **R** | Right-Angle (90-degree) pins OR Reverse orientation | ---
