The half-pitch connectors of the 8822 Series are used for board-to-cable connections.
Specifically, they facilitate connection of a pair of flat cables of 1.27-mm pitch.
In addition, a pair of MIL-compliant connectors can also be connected - one of half pitch; the other, of 2.54mm pitch.
The 8822 Series employs a one-touch lock mechanism.
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.
