The **M2AS1-5322-R/Q** is a high-performance **Micro-D connector** manufactured by Airborn. These connectors are designed for applications requiring high reliability, extreme durability, and space efficiency, often found in military, aerospace, and medical electronics. --- ### ## Technical Specifications Overview Below are the key specifications for this specific part number: | Feature | Specification | | :--- | :--- | | **Series** | M-Series (Micro-D) | | **Number of Contacts** | 51 Contacts | | **Contact Gender** | Socket (Female) | | **Termination Style** | Straight PC Lead (Thru-hole) | | **Shell Material** | Aluminum Alloy | | **Plating** | Electroless Nickel | | **Mounting Hardware** | Jackposts (Fixed) | | **Pitch** | 0.050" (1.27 mm) | --- ### ### Component Breakdown #### 1. The Shell (Electroless Nickel) The "R" suffix typically denotes the shell plating. **Electroless Nickel** provides excellent corrosion resistance and electromagnetic interference (EMI) shielding. The aluminum body keeps the connector lightweight while maintaining structural integrity. #### 2. Contact System (Pin/Socket) Airborn Micro-D connectors use a specialized **twist-pin contact** system. * **Reliability:** Provides 360° of contact surface area. * **Vibration Resistance:** Designed to maintain electrical continuity under high-G vibration and shock. #### 3. Termination: Straight PC Lead The "5322" designation refers to the specific tail length and orientation. These are rigid leads designed to be soldered directly into a Printed Circuit Board (PCB). This is ideal for "mother-daughter" board configurations or internal box wiring. --- ### ### Typical Applications * **Avionics:** Flight control systems and cockpit displays. * **Defense:** Missile guidance systems and tactical radios. * **Space:** Satellite instrumentation where outgassing and weight are critical factors. * **Industrial:** High-end robotics or down-hole drilling equipment. --- ### ### Part Number Decoder (Breakdown) While specific to the Airborn catalog, here is the functional logic of the code: | Segment | Meaning | | :--- | :--- | | **M2AS** | M-Series, 2-Row, Aluminum Shell, Socket | | **1** | Insulator Material (typically Polyphenylene Sulfide) | | **53** | Number of contacts (51 used in standard 2-row configuration) | | **22** | Termination length/type (Straight PC Lead) | | **R/Q** | RoHS Compliant / Quality Grade designation |
