Based on your query, the **MA6L1FAD-R** is an alphanumeric code typically associated with **Micro-D connectors**, specifically those following the MIL-DTL-83513 standards. These are high-density, subminiature connectors used in aerospace, defense, and high-reliability industrial applications. Below is a breakdown of the electronic and mechanical characteristics associated with this part series. --- ## 1. Technical Specifications Table | Feature | Specification Details | | :--- | :--- | | **Connector Type** | Micro-D (Subminiature D) | | **Contact Density** | 0.050" (1.27 mm) Pitch | | **Current Rating** | 3 Amps maximum | | **Operating Temperature** | -55°C to +125°C | | **Insulation Resistance** | 5000 MΩ minimum | | **Dielectric Withstanding** | 600 VAC at sea level | | **Contact Material** | Copper Alloy with Gold Plating | --- ## 2. Part Number Breakdown (Typical) While specific manufacturer prefixes can vary (e.g., Glenair, ITT Cannon, or AirBorn), the code generally follows this logic: ### Key Electronic Components: 1. **MA (Series):** Identifies the Micro-D series designed for high-density environments where space is a premium. 2. **6 (Shell Size/Layout):** Refers to the number of contacts (often 9, 15, 21, 25, 31, 37, 51, or 100 pins). In this specific nomenclature, "6" usually maps to a **25-pin** configuration. 3. **L (Insulator):** Liquid Crystal Polymer (LCP) or Polyphenylene Sulfide (PPS), providing high heat resistance and electrical insulation. 4. **1 (Hardware):** Indicates the mounting hardware (e.g., jackposts or threaded inserts). 5. **FA (Contact Type):** "F" often denotes **Female** (Socket) contacts, and "A" refers to the termination style (e.g., straight PC tail or solder cup). 6. **D-R (Plating/RoHS):** "D" indicates a Cadmium or Nickel shell finish, and "**-R**" signifies **RoHS Compliance** (Lead-free). --- ## 3. Electronic Performance Features ### Twist Pin Technology The core electronic advantage of the MA6 series is the **Twist Pin** contact system. Unlike standard stamped contacts: * It provides 7 points of electrical contact. * It maintains continuity under extreme vibration and shock. * It reduces contact resistance even after hundreds of mating cycles. ### Shielding and EMI The shell is typically made of aluminum alloy with electroless nickel plating. This provides a conductive path for **EMI/RFI shielding**, ensuring that signals passing through the pins are not corrupted by external electromagnetic interference. --- ## 4. Common Applications * **Avionics:** Flight control systems and cockpit displays. * **Medical:** High-resolution imaging equipment. * **Space:** Satellite communication modules. * **Downhole Drilling:** High-temperature sensors.
