What This Connector Is — Hirose DF12NB(3.0)-30DP-0.5V(51)
The Hirose DF12NB(3.0)-30DP-0.5V(51) is a 30-position header with outer shroud contacts from the DF12 series, designed for board-to-board mezzanine stacking at a tight 0.50 mm pitch. This is the plug side — the male header that mates with the matching DF12 receptacle, delivering a mated stack height of 3 mm. It is a Surface Mount component, dual-row, and the base product number DF12N identifies the variant within the DF12 family. Typical applications include compact handheld devices, camera modules, and any PCB stack where z-height budget is tight and signal density is high.
For moderate mating cycles in consumer electronics or industrial sensor boards, this is adequate. Thin flash plating like this will not survive high-cycle field servicing the way 30 µin gold would, but for a board-to-board mezzanine that mates once at assembly and stays mated, the duty cycle is low. If your application requires repeated disconnect and reconnect in the field, consider a thicker plating variant in the DF12 series.
