The **M2AS1-4114-R** is a specific part number typically associated with high-density, multi-pin electrical connectors, often used in aerospace, military, or industrial automation applications. It is commonly part of the **M2 series** (or similar micro-miniature series) designed for rugged environments. --- ### 1. Technical Specifications Overview Based on standard industry nomenclature for this series, here is the breakdown of the electronic and mechanical characteristics: | Feature | Specification | | :--- | :--- | | **Component Type** | Circular or Rectangular Micro-Connector | | **Number of Pins** | Usually 4 to 14 (depending on suffix sub-type) | | **Termination Style** | Solder Cup or PCB Mount | | **Shell Material** | Aluminum Alloy / Stainless Steel | | **Plating** | Electroless Nickel or Gold (RoHS Compliant) | | **Operating Temperature** | -55°C to +125°C | | **Current Rating** | ~3A per contact (Signal level) | --- ### 2. Key Electronic Components & Materials #### A. Contact Pins * **Material:** Usually made of a copper alloy for high conductivity. * **Plating:** Gold plating is standard to prevent oxidation and ensure low contact resistance over thousands of mating cycles. #### B. Insulator Body * **Material:** High-grade thermoplastic (such as Polyphenylene Sulfide - PPS) or Liquid Crystal Polymer (LCP). * **Function:** Provides high dielectric strength to prevent electrical arcing between closely spaced pins. #### C. Environmental Sealing (The "R" Suffix) * The **"R"** in the part number often denotes **RoHS Compliance** or **Environmental Sealing** (Rubber/Resin gaskets). This ensures the connection is protected against moisture, dust, and chemical ingress. --- ### 3. Applications These parts are engineered for high-reliability environments where failure is not an option: 1. **Avionics:** Flight control systems and cockpit instrumentation. 2. **Medical Imaging:** High-density signal transmission in MRI or ultrasound equipment. 3. **Defense:** Portable communication devices and ruggedized computers. 4. **Robotics:** Sensors and actuators requiring compact, vibration-resistant connections. --- ### 4. Part Number Decoding (Typical) While manufacturers vary slightly, the code usually follows this logic: * **M2:** Series identifier (Micro-miniature). * **AS:** Assembly Type (e.g., Straight Plug or Receptacle). * **4114:** Specific configuration/insert arrangement. * **R:** Environmental rating or RoHS compliance status.
