The **M2CEC-25002-R2/Q** is a specialized electronic component, typically categorized as a high-reliability **Micro-D connector assembly** or a high-density interconnect system often used in aerospace, defense, and industrial automation. Below is a breakdown of its core electronic and mechanical parts. --- ### 1. Component Specifications The following table outlines the general technical characteristics typical of this series: | Feature | Specification Details | | :--- | :--- | | **Connector Type** | Micro-D (High Density) | | **Contact Density** | 0.050" (1.27 mm) Pitch | | **Current Rating** | ~3 Amps per contact | | **Operating Voltage** | 600 VAC at sea level | | **Insulation Resistance** | 5,000 Megohms minimum | | **Temperature Range** | -55°C to +125°C | --- ### 2. Core Electronic & Physical Parts #### A. Contact Pins and Sockets * **Material:** Usually made from beryllium copper for superior conductivity and spring properties. * **Plating:** Typically features heavy gold plating (e.g., MIL-DTL-83513 standard) to prevent oxidation and maintain low contact resistance in harsh environments. * **Design:** Often utilizes "Twist Pin" technology, which provides multiple points of electrical contact to ensure signal integrity under high vibration. #### B. Insulator/Dielectric Block * **Material:** High-grade polyphenylene sulfide (PPS) or liquid crystal polymer (LCP). * **Function:** This part holds the pins in precise alignment and prevents electrical arcing between adjacent circuits. #### C. Shell (Housing) * **Material:** Aluminum alloy or Stainless Steel. * **Electroless Nickel Plating:** This provides the "R2" designation in many catalogs, signifying a specific finish for EMI/RFI shielding and corrosion resistance. #### D. Termination Type * **Wiring:** The "/Q" suffix often refers to a specific termination style, such as pre-wired "pigtails" (insulated stranded wire) or specific solder cup configurations for PCB mounting. --- ### 3. Typical Applications Due to the ruggedized nature of the M2CEC series, it is found in: 1. **Avionics:** Flight control systems where space and weight are critical. 2. **Medical Imaging:** High-density signal transmission in portable diagnostic equipment. 3. **Space Exploration:** Satellite payloads requiring vacuum-stable materials. ---
