8LT Series - Applications
High contact density connectors with high reliability
This 8LT product family is qualied in accordance to the
MIL-DTL-38999 Series I.
Originally designed to meet the high performance needs of the
aerospace industries & military applications, it is also now used
in varied applications needing extremely reliable interconnections
with high density contact arrangements in a miniature circular shell.
Weight and Space Saving
Quick Mating - 3 point bayonet lock system
Mismating, error proof positioning - keyway polarization (5 positions)
High choice of Insert arrangements (customization possible, please consult us)
Range extension available or on demand (Rack Panel, Potted, Hermetics, Low Prole, Filters, etc..),
please consult us
Versatility thanks to our inserts as for the series III (except for 8LT type 2) with full range of crimp
contacts interchangeable
Gold plated crimp or PC tail contacts are rear removable and retained in the insulator by a metal clip.
RoHS version available (cadmium free)
