The **D369-R33-AP1** is a high-performance, compact connector part of the **D369 Series** manufactured by **TE Connectivity (DEUTSCH)**. These connectors are specifically designed for harsh environments, primarily in aerospace and defense applications where space and weight are critical factors. --- ### 1. Key Technical Specifications The D369 series is known for its rectangular, lightweight composite design. Below are the primary technical attributes: | Feature | Specification | | :--- | :--- | | **Series** | D369 (Aerospace Grade) | | **Contact Layout** | 3-Way (3 Cavities) | | **Contact Type** | Pin (Plug) or Socket (Receptacle) depending on configuration | | **Housing Material** | High-performance composite (PEI) | | **Operating Temp** | -55°C to +175°C | | **Flammability** | Low Smoke, Toxicity, and Flammability (EN45545) | --- ### 2. Breakdown of the Part Number The alphanumeric code provides specific details about the component's build: * **D369**: The base series identifier (DEUTSCH 369). * **R**: Generally denotes the mounting style or orientation (e.g., Receptacle). * **33**: Indicates the contact arrangement (3 positions / size 22 contacts). * **A**: Polarization/Keying code (used to prevent mismatching with other connectors). * **P**: Contact gender (P = Pin/Male). * **1**: Modification code (usually referring to specific plating or packaging). --- ### 3. Electronic & Mechanical Features #### A. Contact System The unit utilizes **AS39029** style contacts (Size 22), which are standard in the aviation industry. They are typically gold-plated copper alloy to ensure high conductivity and resistance to oxidation. #### B. Environmental Sealing The connector features an internal cork-and-bottle interfacial seal and a triple-barrier wire seal. This provides: * Moisture resistance. * Protection against pressure changes at high altitudes. * Resistance to common aerospace fluids (Skydrol, jet fuel). #### C. Integrated Features * **Scoop-proof design:** Prevents damage to pins during blind mating. * **Click-lock mechanism:** Provides audible and tactile feedback to ensure the connector is fully seated. --- ### 4. Common Applications Due to its small footprint and reliability, the D369-R33-AP1 is used in: 1. **Cabin Systems:** In-flight entertainment (IFE), lighting, and seat electronics. 2. **UAVs/Drones:** Where weight savings are paramount. 3. **Avionics:** Signal transmission in flight control systems.
