The **M2AS1-A144-R2** is a specialized high-density connector, typically belonging to the **M2 series** (often associated with manufacturers like AirBorn or similar high-reliability aerospace/defense suppliers). These components are designed for mission-critical environments where space is limited but signal integrity is paramount. --- ### 1. General Specifications & Design The part number follows a specific nomenclature typically representing the number of contacts, mounting style, and plating. | Feature | Description | | :--- | :--- | | **Series** | M2 (High-density rectangular connector) | | **Contact Count** | 144 Pins/Contacts | | **Configuration** | 2-Row or 4-Row (depending on specific spacing) | | **Type** | Board-to-Board or Cable-to-Board | | **Mounting** | Right Angle (R2 designation often indicates specific lead forming) | --- ### 2. Key Electronic Characteristics These parts are engineered for performance under harsh conditions: * **Signal Integrity:** Low crosstalk and high-speed data transmission capabilities. * **Current Rating:** Generally rated for **1 to 3 Amperes** per contact, depending on the wire gauge or PCB trace thickness. * **Operating Voltage:** Typically rated around **300V to 600V AC** (at sea level). * **Dielectric Withstanding Voltage:** Usually tested to 1000V RMS to ensure insulation reliability. * **Contact Resistance:** Extremely low (often < 10-15 milliohms) to prevent heat buildup. --- ### 3. Materials and Durability Electronic components in the M2AS1 series are built to military or industrial-grade standards: * **Contacts:** Usually made of **Copper Alloy** with high-grade **Gold Plating** (e.g., MIL-G-45204) to prevent oxidation and ensure reliable connectivity over thousands of mating cycles. * **Insulator:** High-performance polyphenylene sulfide (PPS) or liquid crystal polymer (LCP), providing excellent thermal stability. * **Environment:** Designed to operate in temperatures ranging from **-55°C to +125°C**. --- ### 4. Common Applications Due to the high pin density (144 pins), this part is commonly found in: 1. **Avionics:** Flight control systems and cockpit displays. 2. **Embedded Computing:** High-speed backplanes and motherboard-to-daughtercard connections. 3. **Military Hardware:** Ruggedized communication devices and telemetry units. 4. **Medical Imaging:** High-resolution sensors requiring many parallel signal paths. ---
