Description

Dual-row box headers for PCB connections

BH401, BH401A, BH402 and BH419M/N/O/P provide shrouded dual-row contact interfaces. Select by both along-row pitch and transverse row spacing, then match the mounting style, body height and PCB footprint. Elevated and surface-mount designs have their own locating and pad arrangements.
