The D38999/24WE26SB is a mil-spec cylindrical extension connector created by the Amphenol Corporation. The connector design features signal, power, coax, triax, and fiber optic contacts. As a result, the D38999/24WE26SB connector is a popular choice in the aerospace and defense industries. The goal of the connector design is to provide electrical connections in those environments, that can withstand harsh environmental conditions.

Connector Overview

The D38999/24WE26SB connector is designed to accept 26 contacts. The contacts are arranged in three-row blocks, providing a total of 8 contacts per row. Connectors are available with either reversed (female) polarization or standard (male) polarization, based on the application requirements. The contacts themselves consist of crimp or solder contact with either stainless steel or gold plating. The insulators are either copper alloy, cadmium-plated copper alloy, or aluminum alloy.

Environmental Ratings

One of the important considerations in selecting the D38999/24WE26SB connector is its environmental ratings. The environmental ratings are generally determined by the contact contacts and insulators. As a result, they vary depending on the type of contacts and insulators installed in the connector. Generally, these connectors can withstand vibration up to a Class 6 rating for frequency and acceleration, as well as temperature ranges from -65 to +150°C. Additionally, these connectors are rated to IP67, IEC 60529, MIL-STD-202F, EIA-364-35F.

Applications

The D38999/24WE26SB connector is a popular choice for applications found in harsh environments. Its connection capabilities make it a great choice for applications found in aerospace, defense, marine, and industrial applications. Its design can provide a reliable electrical connection in areas that require reliable and robust connections, such as underneath the hood of a fighter jet or inside the cabin of a submarine.

Working Principle

The D38999/24WE26SB connector works by relying on physical contact between pins or sockets on the connectors. This allows the electrical current to flow through the metal contacts. The crimp contacts ensure that the connections remain intact and robust for long periods of time. This also prevents any water or moisture from passing through the connection, which can cause problems in some harsh environments. Additionally, the insulators provide additional protection and help to ensure that there is no unwanted current leakage.

Conclusion

The D38999/24WE26SB connector is an ideal choice for applications found in harsh environments. Its reliable and robust design makes it a great choice for defense, marine, aerospace, and industrial applications. Its contacts and insulators provide reliable electrical connections in areas that require secure connections. Additionally, its environmental ratings make it well suited for applications in a wide range of temperatures, vibrations, and other harsh conditions.
