FEATURES

ITT CANNON KJL SERIES 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 coax 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.
