series introduction
# Introduction to the D38999/20MG11PN Product Series
## 1. Overview
The D38999/20MG11PN product series belongs to the high - performance circular connector family, which is widely recognized in the aerospace, military, and industrial sectors for its exceptional reliability, durability, and electrical performance. These connectors are engineered to meet the most demanding requirements of modern electronic systems, ensuring seamless data and power transmission in harsh environments.
## 2. Design and Construction
### 2.1 Shell Design
- The connectors in the D38999/20MG11PN series feature a rugged circular shell made of high - strength aluminum alloy. This material provides excellent mechanical protection against impacts, vibrations, and corrosion. The shell is also designed with a unique plating process that enhances its resistance to environmental factors such as salt spray, humidity, and extreme temperatures.
- The shell has a threaded coupling mechanism, which ensures a secure and reliable connection. The threaded design allows for easy mating and unmating of the connectors, while also providing a high level of resistance to shock and vibration. This makes the connectors suitable for use in applications where there are significant mechanical stresses, such as in aircraft and military vehicles.
### 2.2 Contact Arrangement
- Inside the shell, the D38999/20MG11PN connectors are equipped with precision - machined contacts. The contact arrangement is carefully designed to optimize electrical performance and minimize signal interference. The contacts are made of high - conductivity materials, such as copper alloy, which ensures low resistance and efficient power and signal transmission.
- The series offers a variety of contact configurations to meet different application requirements. Whether it is for power distribution, data communication, or control signals, there is a suitable contact arrangement available. The contacts are also designed to be easily replaceable, which simplifies maintenance and reduces downtime in case of contact failure.
### 2.3 Sealing and Environmental Protection
- To ensure reliable operation in harsh environments, the D38999/20MG11PN connectors are equipped with high - quality sealing gaskets. These gaskets provide an effective barrier against dust, water, and other contaminants. The connectors are rated to meet IP67 or higher environmental protection standards, which means they can withstand immersion in water for a certain period without any damage to the internal components.
- In addition to the sealing gaskets, the connectors also have a hermetic sealing option available. Hermetic sealing is particularly important in applications where the connectors are exposed to high - pressure or high - altitude environments, such as in aerospace applications. The hermetic seals prevent the ingress of moisture and gases, ensuring the long - term reliability of the connectors.
## 3. Electrical Performance
### 3.1 Current - Carrying Capacity
- The D38999/20MG11PN connectors are designed to handle high currents. The contact size and material selection are optimized to ensure that the connectors can carry the required current without overheating. Depending on the specific contact configuration, the connectors can carry currents ranging from a few amperes to several tens of amperes.
- The high current - carrying capacity makes the connectors suitable for power - hungry applications, such as in military vehicles, where they can be used for power distribution to various electrical systems.
### 3.2 Signal Transmission
- For data and signal transmission, the D38999/20MG11PN connectors offer excellent electrical performance. They have low insertion loss and high return loss, which means that the signals can be transmitted with minimal distortion and interference. The connectors are also designed to support high - speed data transmission, making them suitable for applications such as avionics systems, where high - speed data communication is essential.
