JT - 38999 Series II description
The JT connectors from Amphenol Socapex are designed in accordance with the MIL-DTL-38999 series II standard, making them ideal for use in the military and aerospace industry. These connectors offer a range of features that make them a reliable and durable solution for various applications, including battlefield communication, grounded vehicles, and military avionics.
One of the key features of the JT connectors is their large variety of contact arrangements and shell types, which allows for customization to meet specific requirements of various applications. Additionally, the connectors provide maximum weight/space savings, making them suitable for use in applications where space is limited. This feature is particularly important in the aerospace industry, where every ounce counts. The JT connectors also provide 100% contact protection, which ensures that the contacts are not damaged during use, providing additional reliability and durability. They are available in both metallic and composite versions, providing options for different environmental conditions and weight requirements.
The JT connectors are available in three finish options: olive drab cadmium plating, electroless nickel plating, and black zinc nickel plating. These finishes offer corrosion resistance and protect the connectors from harsh environmental conditions.
The JT connectors are available in nine shell sizes, ranging from 08 to 24, which provides flexibility in their use across different applications. The connectors offer more than 50 arrangements of contacts, with size 12, 16, 20, and 22D contacts available. Additionally, crimp, PCB, signal, and power contacts are available, providing customization options for various applications. While pin contacts are not scoop-proof protected, the JT connectors offer improved interfacial seal that ensures sealing around each contact, providing additional protection against environmental factors. Additionally, the connectors offer optional grounding fingers on the plug shell, providing EMI/RFI protection.
Finally, the JT connectors are very low profile and lightweight, making them ideal for applications where space and weight are critical factors.
