The part number **D369-R66-C** refers to a high-reliability electrical connector, specifically part of the **D369 series** manufactured by **TE Connectivity (formerly DEUTSCH)**. These connectors are designed for harsh environments, particularly in the aerospace and defense sectors. --- ### Technical Specifications and Description The D369 series is modeled after the BACC65 standard and is known for its compact, lightweight, and rectangular design. Below is a breakdown of the technical characteristics: | Feature | Specification | | :--- | :--- | | **Series** | D369 (Aerospace Grade) | | **Connector Type** | Receptacle (In-line) | | **Contact Layout** | 6-Way (6 positions) | | **Contact Type** | Socket (Crimp-type) | | **Shell Material** | Composite (High-performance thermoplastic) | | **Environmental Rating** | IP67 / IP68 (Fluid resistant and sealed) | | **Temperature Range** | -55°C to +175°C | --- ### Part Number Breakdown Understanding the nomenclature helps in identifying the specific configuration: * **D369**: The base series name (TE/DEUTSCH Rectangular Connector). * **R**: Indicates **Receptacle** (The housing that usually stays stationary or is mounted). * **66**: Refers to the insert arrangement (specifically **6 positions** with **6 sockets**). * **C**: Denotes the **Keying/Polarization** (The physical orientation to prevent mismatching with other similar connectors). --- ### Key Features and Applications #### 1. Design Benefits * **Space Saving:** Rectangular shapes allow for tight stacking compared to circular connectors. * **Tool-less Installation:** These often feature a simple push-pull or click-lock mechanism for easy installation in cramped aircraft cabins. * **Weight Reduction:** Made from lightweight composite materials rather than heavy metals. #### 2. Common Use Cases * **Cabin Systems:** In-flight entertainment (IFE), lighting, and seat electronics. * **Aerospace:** UAVs (drones), commercial aircraft, and helicopters. * **Harsh Environments:** Marine or industrial applications where moisture and vibration are prevalent. --- ### Associated Components To use this part effectively, you typically need the following: * **Contacts:** Standard M39029 or specialized D369 crimp contacts (Size 22). * **Mating Part:** The corresponding **Plug** (usually starting with `D369-P66-C`).
