38999 bayonet circular connector for more compacity
The design and performances of the 8T connectors meet the most severe requirements set for applications in
military and civil aerospace. With the increasing requirement for Space, Weight and Power (SWaP) reduction,
SOURIAU has more than doubled its 8T range. It features:
• Lower prole design: Lightweight, space saving (30% shorter compared to 8LT Series)
• High reliability: EMI shielding, excellent shock vibration and uid resistance, QPL approuved
• A high contact density: From 1 to 128 contacts
• A wide range: 11 different shells available, 43 layouts available from size 8 to 24
