What this 10-position shrouded header does
The tin-plated male pins are rated for general-purpose signal duty; the 0.130" post length suits standard through-hole soldering.
Pitch, lock, and board fit
The 0.642" overall contact length and 0.394" mating length mean the header stands tall off the board, which matters if the mating receptacle has a deep cavity. The detent lock is a positive retention feature — it clicks when fully mated and resists unseating from cable strain. No separate latch hardware needed.
