The **M2AS1-6334-R** is a specific part number typically associated with high-performance **Micro-D connectors** (often manufactured by brands like Glenair or ITT Cannon, following MIL-DTL-83513 standards). These connectors are designed for space-constrained environments that require extreme reliability. --- ### 1. Key Technical Specifications The following table outlines the general technical characteristics of this class of electronic component: | Characteristic | Specification | | :--- | :--- | | **Connector Type** | Micro-D (Rectangular) | | **Contact Density** | 0.050" (1.27 mm) Pitch | | **Number of Contacts** | 34 Pins/Sockets (indicated by "34") | | **Mounting Style** | Right Angle (RA) Through-Hole | | **Shell Material** | Aluminum Alloy (usually Nickel or Cadmium plated) | | **Insulator** | Liquid Crystal Polymer (LCP) or Polyphenylene Sulfide (PPS) | | **Current Rating** | 3 Amps maximum | --- ### 2. Breakdown of the Part Number Logic While specific manufacturers have slight variations, the code generally breaks down as follows: * **M2AS1**: Series identifier. "M" usually denotes Military grade or Micro-D series. "AS1" often refers to the specific PCB mounting hardware or shell style. * **63**: Often refers to the shell finish (e.g., Electroless Nickel) or a specific military specification slash sheet. * **34**: The total number of positions/contacts within the connector. * **R**: Typically stands for **Right Angle** PCB orientation. --- ### 3. Electronic & Mechanical Features #### High Reliability Contacts These parts utilize **Twist Pin** technology. Instead of a simple hollow tube, the male pin is made of a bundle of helically wound wires. This ensures: * Multiple points of electrical contact. * Resistance to high vibration and mechanical shock. * Consistent low contact resistance. #### Space and Weight Efficiency Micro-D connectors are roughly 1/3 the size of standard D-Subminiature connectors. This makes them ideal for: * **Avionics:** Flight control systems and cockpit displays. * **Medical:** High-end imaging and diagnostic equipment. * **Space:** Satellite circuitry where every gram of weight matters. --- ### 4. Implementation Details When integrating the M2AS1-6334-R into a PCB design, engineers must account for: 1. **Footprint:** The 1.27mm pitch is much tighter than standard 2.54mm headers, requiring precision PCB routing. 2. **Shielding:** The metal shell provides EMI/RFI protection, which must be grounded to the chassis or PCB ground plane. 3. **Mating:** Ensure the mating connector has the same contact arrangement and hardware (e.g., jackscrews) for a secure lock.
