Amphenol® JT/LJT
high reliability and high contact density with maximum weight and space savings

Amphenol® LJT and JT Series subminiature cylindrical connectors are qualified to MIL-DTL-38999*, Series I and II respectively. These connectors were developed to meet the needs of the aerospace industries, and provided the impetus for development of the MIL-C-38999 specifications, which recently were superseded by MIL-DTL-38999. Meeting or exceeding MIL-DTL-38999 requirements, Amphenol® JT/LJT connectors feature:

• Lightweight, Space Saving Design
• Contact Protection - 100% scoop-proof LJT design prevents bent pins and short circuits during mating
• Quick Positive Coupling - 3 point bayonet lock system
• Mismating Eliminated - with 5 key/keyway design
• Error Proof Alternate Positioning - insured by different key/keyway locations
• EMI Shielding - grounding fingers standard in LJT Series; optional in JT Series
• Nine Shell Sizes and a Variety of Shell Styles
• Contact Options - size 8, 10, 12, 16, 20, 22M and 22D Crimp, Solder, PCB, Wire wrap, Coax, Twinax, Triax, Thermocouple, Fiber Optic and Filter
• Fixed Solder Contacts - per MIL-C-27599 (see page 52 and Amphenol Product Data Sheet 158)
• Hermetic - air leakage limited to 1 X 10-7 cm3 per second optional
• “Breakaway” Lanyard Release Style - available in LJT plugs. Provides quick disconnect of the connector plug and receptacle with axial pull on the lanyard. See pages 38-41.
