The **D369-R66-B** is a specialized high-reliability connector developed by **TE Connectivity (DEUTSCH)**. It belongs to the 369 Series, which is specifically designed for harsh environments, particularly in the aerospace and defense sectors. --- ### 1. General Specifications The D369 series was inspired by the BACC specifications and aims to provide a lightweight, space-saving alternative to traditional circular connectors. | Feature | Specification | | :--- | :--- | | **Manufacturer** | TE Connectivity / DEUTSCH | | **Series** | 369 Series | | **Housing Style** | Receptacle (In-line) | | **Contact Layout** | 6-Way (6 Positions) | | **Contact Gender** | Socket (Female contacts usually installed) | | **Keying** | Keying B (Color coded/Mechanically keyed) | --- ### 2. Key Electronic & Mechanical Features #### A. Contact System * **AS39029 Standard:** Uses standard Mil-Spec contacts, ensuring high conductivity and reliability under vibration. * **Gold Plating:** Contacts are typically gold-plated to prevent corrosion and maintain signal integrity. #### B. Environmental Sealing * **IP67 Rating:** The "R" in the part number often signifies a version with integrated cork/silicone seals for moisture resistance. * **Triple-Barrier Seal:** Designed to prevent fluid ingress, making it suitable for cabin systems and galleys. #### C. Safety & Material * **Smoke/Toxicity Compliance:** The composite shell is made from high-performance thermoplastic that meets FAR 25.853 and ABD0031 smoke and toxicity requirements. * **Shielding:** While this specific part is usually non-shielded (composite), it provides excellent insulation between circuits. --- ### 3. Applications The D369-R66-B is primarily found in: 1. **Commercial Aircraft:** Cabin lighting, seat electronics, and oxygen masks. 2. **Helicopters:** Flight control systems and communication lines. 3. **UAVs:** Light-weight signal routing. 4. **Military Vehicles:** Interior electronics where weight is a critical factor. --- ### 4.
