The half-pitch connectors of the 8822E Series are used for board-to-cable connections.
Specifically, they facilitate connection of a pair of flat cables of 1.27mm pitch.
In addition, a pair of MIL-compliant connectors can also be connected - one of half pitch; the other, of 2.54mm pitch.
The main feature of the 8822E Series is the Eject Lock - a unique locking mechanism developed by KEL.
Typically, MIL-compliant flat-cable connectors have featured a lock on the board side and required the use of both hands for unlock and removal.
With this series, however, the locking mechanism is provided on the cable side, allowing one-handed release and thus improving the efficiency of assembly operations.
