Manufacturer of Highly Engineered Connector Solutions
INTERMATEABLE WITH ALL 38999-STYLE SERIES I CONNECTORS
ITT Cannon KJL 38999-Style Series I connectors offer high-density contact arrangements in a lightweight miniature circular connector. IKJL series connectors were originally designed for military vehicles are an industry standard for military and aerospace/harsh enviornment applications, built to tackle the most extreme conditions with exceptional versatility.
They are quick-mating, have three-point bayonet coupling, are environmentally sealed, and operate across a wide temperature range.
These 38999-Style connectors are intermateable with Souriau connectors and 38999-Style Series I connectors.
Features
- Quick-Mating
A three-point bayonet coupling system not only makes the KJL quick-mating but also provides an audible and tactile “click,” along with visual verification of mating via a sighting hole and high-visibility, bright blue bayonet pins. - Shielded Interconnect
KJL plugs feature high-quality grounding springs that provide 360-degrees of EMI/RFI-shielding protection. These springs ground the barrel of the KJL plugs to the inside wall of the KJL receptacles with a wiping action that offers effective protection from reception or transmission of electronic noise. - Many Contact Layouts and Styles
KJL connectors come in a wide variety of contact sizes and layouts up to 128 contacts. Printed circuit board, fiber optic, thermocouple, and co-ax style contacts are available for special applications. - Utilizes High-Quality Military Contacts
For standard applications, KJLs come with crimp-style military contacts designed to resist bending and provide reliable performance under the most rigorous conditions. - Corrosion-Resistant
KJLs are available with cadmium over nickel plating that has met and passed the 500 hour military salt spray corrosion tests. - Full Metal Contact Retention Clips
Cannon’s KJL connectors utilize full metal retention clips in their insulators, which assures the highest level of serviceability and unparalleled contact retention.
