series introduction
# Introduction to the D38999/26KC35PN Product Series
## 1. Overview
The D38999/26KC35PN product series belongs to the high - performance circular connector family, which is widely recognized in the aerospace, military, and industrial sectors for its reliability, durability, and excellent electrical performance. These connectors are designed to meet the most demanding environmental and operational requirements, ensuring seamless data and power transmission in harsh conditions.
## 2. Key Features
### 2.1 Robust Construction
- **Shell Material**: The connectors in the D38999/26KC35PN series are typically constructed with a high - strength aluminum alloy shell. This material provides excellent mechanical protection against impacts, vibrations, and abrasions. The shell is also treated with a special coating to enhance its corrosion resistance, making it suitable for use in marine, coastal, and other corrosive environments.
- **Sealing Design**: They feature a reliable sealing mechanism. The connectors are equipped with high - quality O - rings and gaskets that provide both environmental and EMI (Electromagnetic Interference) sealing. This ensures that the internal contacts are protected from dust, water, and other contaminants, and also reduces electromagnetic interference, which is crucial for maintaining signal integrity in sensitive electronic systems.
### 2.2 High - Density Contact Arrangement
- **Contact Configuration**: The D38999/26KC35PN series offers a high - density contact arrangement. With a specific pin - and - socket configuration, it can accommodate a large number of contacts in a relatively small space. This is particularly beneficial in applications where space is limited, such as in avionics systems and military vehicles.
- **Contact Material**: The contacts are made of high - conductivity materials, such as copper alloy. These materials have low resistance, which minimizes power loss during electrical transmission and ensures stable signal transfer. The contacts are also gold - plated to improve their corrosion resistance and reduce contact resistance, further enhancing the overall performance of the connector.
### 2.3 Excellent Electrical Performance
- **Voltage and Current Ratings**: These connectors are designed to handle a wide range of voltage and current levels. They can operate at high voltages, typically up to several hundred volts, and can carry significant currents, depending on the specific contact size and configuration. This makes them suitable for both power and signal transmission applications.
- **Low Insertion Loss and Crosstalk**: The D38999/26KC35PN series exhibits low insertion loss, which means that the signal strength is maintained during transmission. Additionally, the connectors are engineered to minimize crosstalk between adjacent contacts, ensuring that the signals remain clear and distinct, even in high - speed data transmission applications.
### 2.4 Easy Installation and Maintenance
- **Coupling Mechanism**: The connectors are equipped with a quick - coupling mechanism, such as a bayonet or threaded coupling. This allows for easy and rapid installation and removal, reducing downtime during maintenance or system upgrades.
- **Contact Accessibility**: The design of the connectors provides easy access to the contacts, making it convenient to inspect, clean, or replace individual contacts if necessary. This simplifies the maintenance process and reduces the overall cost of ownership.
## 3. Applications
### 3.1 Aerospace
- **Avionics Systems**: In aircraft, the D38999/26KC35PN 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, these connectors are used to connect different subsystems, including power distribution units, communication modules, and sensor arrays. Their ability to withstand
