series introduction
# Introduction to the D38999/20JD35PN Product Series
## 1. Overview
The D38999/20JD35PN product series belongs to the high - performance circular connector family, which is widely recognized in the field of electrical and electronic interconnection systems. These connectors are engineered to meet the demanding requirements of various industries, offering reliable and efficient connectivity solutions in harsh environments.
## 2. Design and Construction
### 2.1 Shell Design
- **Material**: The connector shell is typically made of high - strength aluminum alloy. This material provides excellent mechanical protection and is also lightweight, which is crucial for applications where weight is a concern, such as aerospace and aviation.
- **Finish**: It is often finished with a corrosion - resistant coating, such as cadmium or nickel plating. This coating not only protects the shell from environmental factors like moisture, salt spray, and chemicals but also enhances the connector's overall durability and longevity.
- **Threaded Coupling**: The D38999/20JD35PN series features a threaded coupling mechanism. This design ensures a secure and vibration - resistant connection between the plug and the receptacle. The threaded coupling can be easily tightened by hand or with a simple tool, providing a reliable mating that can withstand high levels of shock and vibration.
### 2.2 Contact Arrangement
- **Pin and Socket Configuration**: The connectors in this series have a specific pin and socket arrangement. The "35" in the model number indicates the number of contacts. These contacts are precisely arranged in a circular pattern within the connector body. The pins are made of high - conductivity materials, such as copper alloy, to ensure low electrical resistance and efficient signal transmission.
- **Contact Insertion and Retention**: The contacts are designed for easy insertion and reliable retention. They are held in place by a robust contact retention system that prevents them from coming loose during normal use or under mechanical stress. This ensures stable electrical connections and reduces the risk of intermittent signals.
### 2.3 Sealing
- **Environmental Sealing**: To protect the internal contacts from dust, water, and other contaminants, the D38999/20JD35PN series is equipped with high - quality sealing gaskets. These gaskets are made of elastomeric materials that provide an effective seal between the plug and the receptacle, as well as around the cable entry point. The sealing performance is often rated according to international standards, such as IP (Ingress Protection) ratings, ensuring that the connector can be used in a wide range of environmental conditions.
## 3. Electrical Performance
### 3.1 Current - Carrying Capacity
- Each contact in the D38999/20JD35PN series is designed to carry a specific amount of current. The current - carrying capacity is determined by factors such as the contact material, cross - sectional area, and the connector's overall design. These connectors can typically handle moderate to high currents, making them suitable for power distribution and high - power signal transmission applications.
### 3.2 Voltage Rating
- The connectors are rated for a specific voltage, which indicates the maximum voltage that can be safely applied across the contacts without causing electrical breakdown or arcing. The voltage rating of the D38999/20JD35PN series is designed to meet the requirements of various electrical systems, ensuring safe and reliable operation.
### 3.3 Signal Transmission
- In addition to power transmission, the D38999/20JD35PN series is also capable of transmitting high - speed signals. The low - resistance contacts and well - designed shielding (if applicable) minimize signal loss and interference, making them suitable for applications such as data communication, control systems, and sensor interfaces.
