The D38999/20FE26PD multi-contact circular connector has a wide range of applications from the military and aerospace market to industrial and commercial markets. It is extremely versatile and robust and is widely used in a variety of harsh conditions. This article provides an overview of the application field and working principle of the D38999/20FE26PD connector.

Application Field

The D38999/20FE26PD connector is primarily used in the defense and aerospace industry, including aircraft, communications, weapons systems, and military electronics. It is also commonly used in many commercial or industrial applications, such as in rail and track equipment, heavy equipment, control instrumentation, professional audio and video, and automated test equipment. The connector is also frequently used in off-road, mining, oil and gas, and marine applications because of its ability to withstand harsh environmental conditions.

Design

The D38999/20FE26PD connector is designed to meet a range of MIL-DTL-38999 backshell specifications and is capable of dealing with high vibration and other extreme environmental conditions. It is equipped with a unique floating-pin contact system, which ensures reliable contact despite high vibration and extreme environmental conditions. The connector is available in many different shell sizes and configurations with an array of contacts. The contact cavities are pre-filled with a dielectric gel to help ensure consistent contact.

Materials

The D38999/20FE26PD connector is made of a blend of aluminum and zinc alloy, providing a strong and corrosion-resistant structure. The aluminum alloy provides corrosion resistance while the zinc alloy provides high-strength and durability. The contact pins and sockets are made of a beryllium-copper alloy and are corrosion-resistant and capable of withstanding extreme temperature and electrical signals. The connector also features a sealed backshell and a blend of fluoropolymer housing materials that provide excellent environmental protection.

Working Principle

The D38999/20FE26PD connector features a floating pin contact system, which consists of a series of pins and corresponding sockets that move independently of each other within the cavity. This flexibility provides a secure electrical connection regardless of the conditions, such as vibration or harsh environmental conditions. As the connector is mated, the floating pin system will engage and the pins and sockets will compress slightly to ensure a secure connection.

Advantages

The D38999/20FE26PD connector offers a range of advantages such as its robust and reliable design, and its ability to withstand high vibration, harsh environmental conditions, and extreme temperature. It is also corrosion-resistant and capable of carrying a high electrical signal. In addition, the pre-filled dielectric gel helps ensure consistent contact and the unique floating pin contact system helps ensure reliable contact even under extreme conditions.

Conclusion

The D38999/20FE26PD multi-contact circular connector is a versatile and robust connector that is suitable for a wide range of applications, from the aerospace and military markets to industrial and commercial markets. Its unique floating pin contact system ensures reliable contact even under harsh conditions, and its robust and corrosion-resistant design makes it capable of carrying a high electrical signal. The D38999/20FE26PD connector is an ideal choice for any application that requires a reliable connection under extreme environmental conditions.
