series introduction
# Introduction to the D38999/20JE35SN Product Series
## 1. Overview
The D38999/20JE35SN 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 environmental and operational requirements, ensuring seamless data and power transmission in harsh conditions.
## 2. Design and Construction
### 2.1 Shell Design
- **Material**: The connector shell is typically made of high - strength aluminum alloy. This material offers excellent mechanical properties, including high tensile strength and good corrosion resistance. The aluminum alloy shell is also lightweight, which is crucial in applications where weight reduction is a priority, such as aerospace.
- **Finish**: It is often finished with a special plating, such as cadmium or nickel. Cadmium plating provides superior corrosion protection in marine and high - humidity environments, while nickel plating is preferred in applications where cadmium is restricted due to environmental regulations. The plating also enhances the shell's electrical conductivity and provides a smooth surface for easy mating and unmating.
- **Threaded Coupling**: The D38999/20JE35SN series features a threaded coupling mechanism. This design ensures a secure and vibration - resistant connection between the plug and the receptacle. The threads are precisely machined to provide a tight fit, preventing accidental disconnection even under high - vibration or shock conditions.
### 2.2 Contact Design
- **Contact Material**: The contacts are made of high - conductivity copper alloy, which offers low electrical resistance and excellent current - carrying capacity. This ensures minimal power loss and reliable signal transmission, even in high - speed data and high - power applications.
- **Contact Configuration**: The series offers a variety of contact configurations, including different pin counts and arrangements. The D38999/20JE35SN specifically has a well - defined pin layout that is optimized for specific electrical requirements. The contacts are precisely positioned within the connector body to ensure proper alignment and mating.
- **Contact Termination**: There are multiple contact termination options available, such as crimp, solder, and wire - wrap. Crimp termination is the most commonly used method as it provides a reliable and gas - tight connection between the contact and the wire. Solder termination is suitable for applications where a more permanent and low - resistance connection is required, while wire - wrap termination is often used in prototype or low - volume production.
## 3. Electrical Performance
### 3.1 Current Rating
The D38999/20JE35SN connectors are designed to handle a wide range of current loads. Depending on the contact size and configuration, the current rating can vary from a few amperes to several tens of amperes. This makes them suitable for both low - power signal transmission and high - power applications, such as power distribution in military vehicles or aircraft.
### 3.2 Voltage Rating
These connectors have a high voltage rating, typically in the range of several hundred volts. This allows them to be used in applications where high - voltage electrical systems are present, such as in some industrial automation equipment or aerospace power systems. The high voltage rating is achieved through careful insulation design and the use of high - quality insulating materials.
### 3.3 Signal Integrity
For data transmission applications, the D38999/20JE35SN connectors offer excellent signal integrity. They have low insertion loss and high return loss, which means that the signals can be transmitted with minimal distortion and reflection. This is crucial in high - speed data communication systems, such as those used in military avionics or satellite communication.
