Features
- Quick-Mating
A three-point bayonet coupling system makes the LJTs quick-mating and provides an audible and tactile "click," along with visual verification of mated connectors via a sighting hole and high-visibility, bright blue bayonet pins. - Shielded Interconnect
LJT plugs feature high-quality grounding springs that provide 360-degrees of EMI/RFI shielding protection. These springs ground the barrel of the LJT plugs to the inside wall of the LJT receptacles with a wiping action that offers effective protection from reception or transmission of electronic noise. - Many Contact Layouts and Styles
LJT connectors come in a wide variety of contact sizes and layouts, up to 128 contacts. Printed circuit board, fibre optic, thermocouple, and co-ax style contacts are available for special applications. - Utilizes High-Quality Military Contacts
For standard applications, LJT's come with crimp-style military contacts design to resist bending and provide reliable performance under the most rigorous conditions. - Corrosion-Resistant
LJT's are available with cadmium over nickel plating that has met and passed the 500-hour military salt spray corrosion tests.
