The 0022022045: Board hooks on the housing latch into plated through-holes during wave solder, holding the connector flush to the board and preventing float. The push-pull fastening means no secondary locking hardware — the receptacle mates and unmates by hand.

Frequently asked questions
Is 0022022045 compatible with standard 0.1 inch pin headers?
The push-pull retention holds the pair without latches.
Does 0022022045 have board hooks?
Yes — the housing includes board hooks that snap into the PCB during through-hole soldering, providing mechanical retention against cable strain and preventing the connector from lifting off the board.
