Amphenol JT/LJT Subminiature Cylindrical Connectors
MIL-DTL-38999 Series I and II

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aerospace industries, and provided the impetus for development of the MIL-C-38999 specifications, which recently were superseded by MIL-DTL-38999.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
• Hermetic - air leakage limited to 1 X 10-7 cm3 per second optional
• Inventory Support Commonality - uses standard MIL-C-38999 contacts, insert arrangements and application tools.

Where proof of high reliability and lot control is required,
MS approved equivalents to most proprietary JT and LJT
connectors are available.

* MIL-DTL-38999 Series I supersedes MIL-C-38999 Series I. MIL-DTL-38999 Series II supersedes MIL-C-38999 Series II.
