LF and Coaxial Military PCB Connector for Extreme Conditions
The 2 row, HE801/HE809 two part printed circuit board connector system utilises a 1.27mm(0.05in.) staggered pitch with 2.54mm(0.1in.) between rows. |
|
Designed to meet the severest of environmental technical requirements from fast jets to gun turrets they have featured on such military programmes as the A300/320, Ariane, Exocet, Ptarmigan, Rapier and also on railway rolling stock applications, where high resistance to abrasion and extreme reliability are critical.
The l.f./audio connectors are available in 9 sizes from 17 to 96 ways. The mixed layout styles provide the addition of 3 or 6 cavities capable of accepting either coaxial or high power inserts in 10 sizes from 5 + 3 to 53 + 3 combinations.
Also available are HE809/810, 3 row High Density models again mainly dedicated to aeronautic and military connector applications. |
