The **D369-R99-AP0** is a specific part number within the **TE Connectivity (DEUTSCH) 369 Series**. This series is a high-reliability, lightweight connector system designed primarily for aerospace, defense, and harsh industrial environments. Below is the detailed breakdown of its electronic and mechanical characteristics. --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | TE Connectivity / DEUTSCH | | **Series** | 369 Series | | **Connector Type** | Rectangular Shell (In-line or Flange Mount) | | **Contact Gender** | Pin (Male) | | **Number of Positions** | 9 Positions | | **Termination Style** | Crimp / Solder (Depending on contact choice) | | **Current Rating** | 5 Amps per contact | | **Operating Temperature** | -55°C to +175°C | --- ### 2. Part Number Breakdown The alphanumeric code provides specific details about the configuration: * **D369**: The base series (Aerospace-grade composite connectors). * **R**: Indicates the shell style (typically **Receptacle**). * **9**: Refers to the arrangement/number of contacts (9-way). * **9**: Refers to the shell keying/polarization. * **A**: Modification code (often signifies standard color or plating). * **P**: Contact type (**P** for Pin / Male). * **0**: No contacts included (shipped as a shell only for field assembly). --- ### 3. Key Electronic Features #### High-Performance Materials The connector is made from high-performance composite plastics. This ensures it is non-conductive and provides excellent insulation resistance, preventing electrical arcing between the 9 pins even in high-humidity environments. #### Environmental Sealing The unit features an integrated triple-barrier wire seal and a cork-in-bottle interfacial seal. This provides an **IP67 rating**, protecting the electrical signals from moisture, dust, and pressure changes common in aviation. #### EMI Shielding (Optional) While the standard composite is non-conductive, certain variants in this series offer selective plating for Electromagnetic Interference (EMI) protection to ensure signal integrity for low-voltage data transmission. --- ### 4. Common Applications Due to its small footprint and reliability, the D369-R99-AP0 is used in: * **Cabin Systems:** Lighting, seat actuation, and in-flight entertainment. * **UAVs:** Drone flight control systems where weight is critical. * **Medical Equipment:** High-density signal routing in portable devices. ---
