D38999 series contribute to high-reliability applications

A versatile and durable solution for military, aerospace and harsh environment applications. The D38999 series is a circular, high-density connector designed to withstand up to 500 mating/disconnection cycles in harsh environments. With a range of body styles, contact termination options, body materials and platings, this family of connectors is ideal for a wide variety of electronic, mechanical and environmentally demanding applications.

The D38999 series is often referred to as a mil-spec connector because it meets the requirements of Airbus specification BACC63 and Boeing specification EN3645. These circular, screw-coupling connectors have a range of shell sizes from #8 to size 24 and over 40 QPL-approved insert arrangements. They provide reliable connections that can withstand high vibration, shock and fluid ingress (e.g. salt spray) and operating temperatures up to 200 degC. They also offer EMI shielding and are hermetic.

Souriau High Performance Connector D38999 series connectors are miniature, high-density bayonet, threaded, or breech coupling, circular, environment resistant electrical interconnects with removable crimp contacts. They are used for cable-to-panel I/O applications in military aerospace and other demanding situations. They are available in four series, each with a range of insert arrangement sizes, shell sizes and platings to suit different application requirements.

How does the D38999 series contribute to high-reliability applications?

These hermetic connectors are suitable for a broad variety of applications, from simple signal transmission to high speed data transmission and are offered in a full range of contact arrangements, including standard pin or socket contacts, thermocouple contacts and PC-tail contacts. They are compatible with most standard MIL-DTL-38999 connectors, but provide the advantages of a higher contact density, superior fluid resistance and improved EMI/RFI shielding.

A major benefit of these rugged connectors is the ratcheting system that prevents accidental disconnections. This allows them to be used in vibration-intensive applications and even in harsh or corrosive marine environments. The unique design also offers exceptional strength and reliability, making them an excellent choice for military use in land vehicles, armored carriers and tanks or any other environment that may involve severe shock or exposure.

In addition to the ratcheting system, these connectors feature a scoop proof design that protects the contact and a metal to glass hermetic seal that is rated up to 1000 mating/disconnection cycles. They are also able to withstand extreme shock, exposure and vibration, providing unmatched performance in harsh environment applications.

The Souriau 8D series is a high-reliability connector compliant with the main standards (MIL-DTL-38999 series III, EN3645, BgACC63). Available in five high end materials and platings (8D aluminum, 8D composite, 8D titanium, 8D stainless steel and 8D bronze), this product line can meet all of your corrosion, shock, endurance or firewall capability needs.

To ensure the correct fit, each connector is designed with a precision machined shell and insert, which creates an extremely robust interconnection that is well suited for extreme conditions. TopFlite specializes in customizing the D38999 series connector to meet customer specific requirements and can include special features such as extended body lengths, specialty insert arrangements, flange sizes or types, integrated backshells and fully sealed solutions. These specialized options are reflected in the part number by adding a Z-Code to the end of the part number nomenclature.
