# Introduction to the D38999/26MA98SA Product Series
## 1. Overview
The D38999/26MA98SA product series belongs to the high - performance circular connector family, which is widely recognized in the aerospace, military, and other demanding industries. These connectors are engineered to provide reliable electrical connections in the most challenging environments, ensuring seamless data and power transmission.
## 2. Key Features
### 2.1 Robust Construction
- **Material Selection**: The connectors in the D38999/26MA98SA series are typically constructed with high - strength aluminum alloy shells. This material offers excellent mechanical protection against impacts, vibrations, and abrasions. The shells are also treated with a special corrosion - resistant coating, which can withstand harsh environmental conditions such as salt - fog, humidity, and extreme temperatures.
- **Sealing Design**: They are equipped with high - quality sealing gaskets. These gaskets provide an IP67 or higher level of protection, preventing the ingress of dust, water, and other contaminants. This makes the connectors suitable for use in outdoor and underwater applications where environmental protection is crucial.
### 2.2 High - Density Contact Arrangement
- **Contact Configuration**: The D38999/26MA98SA series features a high - density contact arrangement. It can accommodate a large number of contacts in a relatively small space, allowing for efficient use of panel real - estate. This is particularly important in applications where space is limited, such as in avionics systems and military vehicles.
- **Contact Types**: The contacts are available in different types, including pin and socket contacts. They are made of high - conductivity materials such as copper alloy, which ensures low resistance and efficient power and signal transmission. The contacts are also gold - plated to enhance their corrosion resistance and electrical performance.
### 2.3 Excellent Electrical Performance
- **Low Resistance**: The high - conductivity contact materials and precise manufacturing processes result in low contact resistance. This reduces power losses and heat generation, improving the overall efficiency of the electrical system.
- **High Signal Integrity**: The connectors are designed to minimize signal interference and crosstalk. They have excellent impedance matching characteristics, which ensure the accurate transmission of high - speed signals. This makes them suitable for use in high - speed data communication applications, such as in radar systems and satellite communication equipment.
### 2.4 EMI/RFI Shielding
- **Shielding Effectiveness**: The D38999/26MA98SA series is equipped with effective electromagnetic interference (EMI) and radio - frequency interference (RFI) shielding. The metal shells act as a shield, preventing external electromagnetic fields from interfering with the internal electrical signals and also preventing the connectors from radiating electromagnetic energy.
- **Grounding Design**: A proper grounding mechanism is incorporated into the connector design to ensure the effectiveness of the shielding. This helps to maintain the integrity of the electrical system and comply with electromagnetic compatibility (EMC) standards.
## 3. Application Areas
### 3.1 Aerospace
- **Avionics Systems**: In aircraft, the D38999/26MA98SA connectors are used in various avionics systems, such as flight control systems, navigation systems, and communication systems. Their high - reliability and excellent electrical performance ensure the safe and efficient operation of these critical systems.
- **Satellites**: For satellite applications, the connectors need to withstand the harsh space environment, including extreme temperatures, radiation, and vacuum. The D38999/26MA98SA series meets these requirements and is used for power distribution, data transmission, and sensor connections in satellites.
