The push-pull fastening type means the connection relies on friction retention only; in high-vibration environments, a secondary locking mechanism or adhesive may be needed. The insulation height of 0.100\" (2.54mm) is the same as the pitch, keeping the profile low for dense board layouts.","metaTitle":"77311-122-12 BERGSTIK® Header, 12 Pos, 0.100\" Pitch","metaDescription":"Amphenol ICC (FCI) 77311-122-12 unshrouded male pin header, 12 positions, 0.100\" pitch, through hole, gold mating finish.
