Rated 2A per contact and 250VAC / 350VDC, this header is aimed at signal-level or low-power circuits — think sensor inputs, control signals, or auxiliary power feeds where the current stays well under 2A per line.
Yes, the fastening type is a detent lock — it provides a positive retention click when mated, resisting accidental disconnection from cable pull or moderate vibration.
