What this 6-position header does for an industrial panel
The detent lock and board lock keep the connector seated under vibration, while the shrouded 4-wall housing prevents misalignment during blind mating.
Pitch, plating, and lock: what they mean on the line
At 3.81mm pitch, this header gives more room per circuit than the 2.50mm pitch of the sibling 1-1871673-2, which matters when routing wider traces or higher-voltage lines on the board. A detent lock, rather than a latch, provides a positive snap that resists vibration but still allows one-handed unmating when needed.
