The **D369-R99-CS1** is a specialized electronic component primarily used in aerospace, defense, and high-reliability industrial applications. It belongs to the **D369 series** of connectors manufactured by **TE Connectivity (DEUTSCH)**. These connectors are designed to be lightweight, compact, and compliant with stringent smoke and toxicity standards (BACC, EN4165). --- ### Technical Specifications and Electronic Profile The part number follows a specific nomenclature that defines its physical and electrical characteristics: | Attribute | Specification | | :--- | :--- | | **Series** | D369 (Small, high-reliability connector) | | **Housing Style** | Rectangular, In-line Receptacle | | **Contact Gender** | Socket (Female) | | **Insert Arrangement** | 9-way (9 positions for contacts) | | **Keying** | Type A (Standard orientation) | | **Material** | High-performance composite (Thermoplastic) | | **Sealing** | IP67 rated (Environmental sealing) | --- ### Key Electronic & Physical Features #### 1. Contact Configuration The "R99" indicates an in-line receptacle housing **9 socket contacts**. These contacts are typically size 22D and are gold-plated to ensure low contact resistance and high signal integrity in harsh environments. #### 2. Environmental Protection The "CS" suffix often refers to specific **C**avity **S**eals or grommets. * **Operating Temperature:** -55°C to +175°C. * **Vibration Resistance:** Designed to withstand high-frequency vibrations found in aircraft engines and cabin interiors. * **Fluid Resistance:** Resistant to hydraulic fluids, jet fuel, and cleaning solvents. #### 3. Material Composition Unlike heavy circular connectors (like MIL-DTL-38999), the D369-R99-CS1 uses a **PEI (Polyetherimide)** composite. This reduces weight significantly—a critical factor in aerospace electronics—while maintaining flame retardancy (UL94-V0). --- ### Typical Applications This part is commonly integrated into the following systems: * **In-Flight Entertainment (IFE):** Routing power and data to seat-back screens. * **Cabin Lighting:** Connecting LED modules. * **Avionics Bays:** Interconnecting various Line Replaceable Units (LRUs). * **UAVs and Drones:** Providing ruggedized connections for sensors and flight controllers. --- ### Wiring Data When integrating this part into a circuit, the following wiring parameters are standard: ```text Contact Size: 22 Wire Gauge (AWG): 22 to 26 AWG Current Rating: Approx. 5 Amps per contact Voltage Rating: 500 VAC (at sea level) ```
