D38999/20FE26SN application field and working principle

The D38999/20FE26SN series connector offers the ruggedness, durability, and flexibility required for a wide range of military, aerospace, and industrial applications. The connector is an environmentally-sealed system designed to mate with a wide range of accessories, such as filters, backshells, and blind-mate adapters. It is configured for size 20 and 28 shell sizes with 26 cavities for power and signal contacts.

The MIL-D 38999 Series III systems offer compatibility with existing bayonet-style connectors as well as threaded inserted and fastjack alternatives. In addition, the 8 size 20 shell sizes provide improved flexibility for current and future platform design needs. The COTS Receptacle version allows use on equipment to ensure high level of EMI/RFI protection for most applications.

The size 20 and 28 shell sizes offer superior benefits, providing improved thermal, shock, and vibration protection. The advanced design mechanisms offer improved performance in intense environmental conditions and aid in protecting the system from environmental or dynamic threats. For additional protection, the series also offers a part-for-part replacement for other shell sizes, allowing the same sized connector to be reused or replaced. The system is also capable of low-temperature applications (-54°C to +183°C).

The D38999 system features a positive latching system which results in secure connections that are nearly impossible to defeat when in use. This proactive method prevents accidental disconnecting and enhances reliability. The size 20 and 28 shell sizes also allow enhanced thermal dissipation, reducing the need for additional cooling fans and increasing the flexibility of the system.

The system further benefits from a number of accessories such as military and commercial EMI/RFI backshells, feedthrough filter options, and blind-mate adapters. The commercial and military-grade EMI Flexmovers are equipped with external shielding braid, for improved high frequency performance. The commercial adapter also offers improved reliability, durability, and compatibility.

The D38999/20FE26SN series offers the high performance electrical and mechanical characteristics, and environmental protection necessary to meet a wide range of applications. Connectors are help together with threads and a multiple-lex twist. The shells are equipped with backshell-style connectors also with o-rings for liquid-tight service. The connectors are well-suited for hostile environments such as aviation, ground support, and transportation.
