6-position right-angle header for board-to-board or cable duty
The 1-178137-5 is a 6-position, 2-row header from TE's Dynamic D-3100 series, with a 3.81mm mating pitch and 7.62mm row spacing. It is a shrouded, 4-wall design with a detent lock, intended for board-to-board or cable connections in general-purpose industrial applications. The right-angle orientation places the mating axis parallel to the PCB, which saves vertical space in enclosures where a straight header would not fit.
Board lock and shrouding for vibration resistance
Integrated board locks on the through-hole tails anchor the header to the PCB during reflow and resist shear forces from cable strain or vibration. The 4-wall shroud protects the tin-plated tab contacts from damage during handling and mis-mating. Compared to the gold-plated sibling 1-178137-3 (30.0µin gold on mating surface), this part uses 78.7µin tin on the mating contact. Tin is suitable for fewer mating cycles but costs less per position — a trade-off for high-volume, low-cycle-count builds.
