48-position breakaway header, 2.54 mm pitch
The 4-103149-0-24 is the 48-position member of TE's AMPMODU Mod II breakaway header line, 0.100" (2.54mm) pitch, dual-row, unshrouded, through-hole right-angle termination.
The 3 A per-contact rating and gold mating finish suit repeated mating cycles and moderate current in signal or low-power distribution. The unshrouded breakaway design allows the header to be snapped to the required circuit count — the 48-position version is the full populated length.
