series introduction
# Introduction to the D38999/26WC98HN Product Series
## 1. Overview
The D38999/26WC98HN 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 and efficient electrical connections in the most challenging environments.
## 2. Design and Construction
### 2.1 Shell Design
- The connectors in the D38999/26WC98HN series feature a rugged circular shell. The shell is typically made of high - strength materials such as aluminum alloy or stainless steel. Aluminum alloy shells offer a good balance between strength and weight, making them suitable for applications where weight reduction is crucial, such as in aerospace. Stainless steel shells, on the other hand, provide excellent corrosion resistance, which is essential for use in marine or harsh industrial environments.
- The shell has a precision - machined design with a threaded coupling mechanism. This threaded coupling ensures a secure and vibration - resistant connection, preventing accidental disconnection even under high - vibration conditions. The coupling also provides a hermetic seal when mated correctly, protecting the internal contacts from dust, moisture, and other contaminants.
### 2.2 Contact Arrangement
- Inside the shell, the D38999/26WC98HN series has a well - organized contact arrangement. The contacts are made of high - conductivity materials, usually copper alloy, which ensures low electrical resistance and efficient power and signal transmission.
- The series offers a variety of contact configurations to meet different application requirements. It can support both power and signal contacts in the same connector, allowing for the integration of multiple functions. The contacts are arranged in a specific pattern to minimize crosstalk between adjacent signals, ensuring the integrity of the transmitted data.
### 2.3 Insulation Material
- High - quality insulation materials are used to separate the contacts and prevent electrical short - circuits. These insulation materials have excellent dielectric properties, high temperature resistance, and chemical stability. They can withstand a wide range of temperatures, from extremely cold to very hot environments, without losing their insulating properties.
## 3. Performance Characteristics
### 3.1 Electrical Performance
- **Low Resistance**: The copper alloy contacts in the D38999/26WC98HN series have very low electrical resistance, which reduces power loss during transmission. This is especially important in high - power applications where energy efficiency is a key concern.
- **High Current Capacity**: The connectors are designed to handle high currents. Depending on the specific contact size and configuration, they can carry currents ranging from a few amperes to several tens of amperes, making them suitable for power - hungry equipment.
- **Signal Integrity**: For signal transmission, the connectors offer excellent signal integrity. They have low insertion loss and return loss, which means that the signals can be transmitted accurately over long distances without significant degradation. This is crucial for applications such as data communication and control systems.
### 3.2 Environmental Performance
- **Temperature Resistance**: The D38999/26WC98HN series can operate in a wide temperature range, typically from - 55°C to + 125°C. This allows them to be used in extreme environments, such as in outer space or in high - temperature industrial processes.
- **Moisture and Dust Resistance**: Thanks to the hermetic seal provided by the threaded coupling and the high - quality gaskets, the connectors are highly resistant to moisture and dust. They can be used in outdoor or wet environments without the risk of internal damage due to water or dust ingress.
- **Vibration and Shock Resistance**: The rugged design of the connectors makes them highly resistant to vibration and shock. They
