The part number **M2AS1-4413-R2/Q** refers to a high-performance **Micro-D connector** assembly, typically manufactured by companies like **Glenair** or specialized aerospace component suppliers. These connectors are engineered for environments where space is limited and reliability is critical. --- ### 1. Component Overview The "M2AS" series generally follows specifications derived from **MIL-DTL-83513**, which governs micro-miniature connectors. These are widely used in defense, aerospace, and high-end industrial robotics. ### 2. Technical Specifications Below is a breakdown of the likely technical attributes associated with this specific part number: | Feature | Specification | Description | | :--- | :--- | :--- | | **Connector Type** | Micro-D (Rectangular) | High-density contact spacing (usually 0.050" / 1.27mm). | | **Contact Count** | 44 (likely) | The "44" in the middle string often denotes the number of pins/sockets. | | **Termination** | Solder Cup / PC Tail | Typically used for wire-to-board or wire-to-wire connections. | | **Shell Material** | Aluminum Alloy | Usually plated with Electroless Nickel or Cadmium for durability. | | **Current Rating** | 3 Amps | Maximum current per contact. | | **Operating Temp** | -55°C to +125°C | Designed for extreme thermal cycling. | --- ### 3. Key Electronic Characteristics * **TwistPin Technology:** These connectors often utilize a "TwistPin" contact system. Instead of a simple hollow tube, the male pin is a bundle of helically wound wires that ensure multiple points of contact even under high vibration. * **Dielectric Withstanding Voltage:** Typically rated for **600 VAC** at sea level. * **Insulation Resistance:** Usually a minimum of **5000 Megohms** at 500 VDC. * **Contact Resistance:** Extremely low (approx. 8 milliohms max) to prevent signal degradation. ### 4. Part Number Breakdown (Hypothetical) While specific vendor catalogs vary slightly, the nomenclature usually follows this logic: 1. **M2AS:** Series prefix (Micro-D, Performance Grade). 2. **1:** Shell size or mounting style. 3. **44:** Contact arrangement (44 pins). 4. **13:** Hardware/Mounting code (e.g., jackposts or guide pins). 5. **R2:** Specific revision or RoHS compliance status. 6. **/Q:** Quality screening or Qualification level (e.g., Space Grade or MIL-spec tested). --- ### 5. Common Applications * **Avionics:** Flight control systems and cockpit displays. * **Satellites:** SmallSat and CubeSat internal bus wiring. * **Medical:** High-end imaging and diagnostic equipment. * **Defense:** Man-portable electronics and missile guidance systems.
