The **MHR14FGJ-R** is a specific electronic component, typically categorized as a high-density, miniature connector, often associated with military, aerospace, or high-reliability industrial applications. --- ### 1. Component Identification The part number follows a modular logic often used by manufacturers like **Souriau (Eaton)** or similar high-reliability connector brands. Here is a breakdown of the typical specifications for this series: | Attribute | Specification | | :--- | :--- | | **Component Type** | Rectangular High-Density Connector | | **Series** | MHR Series (Miniature High Reliability) | | **Contact Quantity** | 14 Pins/Contacts | | **Gender** | Female (indicated by "F") | | **Mounting Style** | Through-hole or Guide-pin style (indicated by "G") | | **Termination** | Solder or Crimp (model dependent) | | **RoHS Status** | Compliant (indicated by "-R") | --- ### 2. Key Technical Features High-reliability connectors like the MHR14FGJ-R are engineered for harsh environments. Their electronic and physical characteristics include: * **Miniaturization:** Designed for high-density PCB layouts where space is at a premium. * **Gold Plating:** Contacts are typically plated with gold to ensure low contact resistance and prevent oxidation over long periods. * **Vibration Resistance:** Equipped with locking mechanisms or guide pins (the "G" in the part number) to maintain electrical continuity under mechanical stress. * **Insulation:** Uses high-grade thermoplastics (like PPS or LCP) to ensure high dielectric strength and heat resistance. --- ### 3. Connection Pinout Logic While specific pinouts depend on the system design, the 14-pin configuration is commonly used for: 1. **Low-level Signal Transmission:** Sensors and data bus communications. 2. **Power Distribution:** Low-current DC power rails. 3. **Board-to-Board Interconnects:** Bridging two PCBs in a stacked configuration. --- ### 4. Implementation Example If you are integrating this into a PCB design using EDA software (like Altium or KiCad), the footprint would look like this in code representation: ```markdown # Example Footprint Dimensions (Generic MHR-14) - Pitch: 1.27mm or 2.00mm (check datasheet) - Hole Diameter: 0.6mm - Rows: 2 (7 pins per row) - Housing Material: Glass-filled Polyester ``` --- ### 5. Common Applications * **Avionics:** Cockpit display controls. * **Medical Devices:** Diagnostic equipment requiring high-cycle durability. * **Industrial Automation:** Sensor arrays in robotic arms.
