The **ME12XAD-R** is a specific part number typically associated with **Micro-D connectors** (specifically those conforming to MIL-DTL-83513 standards) or high-density electronic modules used in aerospace and industrial automation. Below is a detailed breakdown of the electronic and mechanical specifications for this component. --- ## 1. Component Overview The ME12XAD-R is generally categorized as a **High-Density Micro-D Connector**. These parts are designed for environments where space is limited but high reliability is required. ### Key Specifications Table | Feature | Description | | :--- | :--- | | **Series** | Micro-D (MIL-DTL-83513 Compatible) | | **Housing Material** | Aluminum Alloy (Electroless Nickel Plated) | | **Contact Gender** | Pin (Male) or Socket (Female) depending on suffix | | **Mounting Type** | Through-hole / Right Angle PCB Mount | | **Current Rating** | 3 Amps per contact | | **Insulation Resistance** | 5000 Megohms minimum | | **Operating Temperature** | -55°C to +125°C | --- ## 2. Electronic Characteristics ### A. Signal Integrity Because these connectors are used in high-density applications, the pin spacing (pitch) is typically **0.050 inches (1.27 mm)**. This allows for a high number of signals in a very small footprint while maintaining low crosstalk. ### B. Contact Resistance The contacts are usually gold-plated to ensure: * Low contact resistance (typically < 8 milliohms). * Prevention of oxidation in harsh environments. * High mating cycle durability (up to 500 cycles). --- ## 3. Part Number Decoding (Nomenclature) While different manufacturers (such as ITT Cannon, Glenair, or Cristek) may vary slightly, the "ME12XAD-R" usually follows this logic: * **ME:** Series designation (Micro-D/Metal Shell). * **12:** Pin count or shell size (indicates the number of signal contacts). * **X:** Mounting hardware configuration (e.g., Jacksolder or threaded insert). * **AD:** Termination type (likely Right-Angle PCB mount). * **R:** RoHS Compliance (Lead-free). --- ## 4. Typical Applications These parts are not found in consumer electronics; they are specialized for: 1. **Avionics:** Flight control systems and cockpit instrumentation. 2. **Medical Equipment:** Portable imaging and diagnostic tools. 3. **Military:** Ruggedized handheld radios and tactical gear. 4. **Space:** Satellite bus systems where weight and vacuum stability are critical. ---
