18-Position, 2.54mm Pitch — Signal-Level Board-to-Board or Cable Header
The full 4-wall shrouding and latch lock keep the mating pair aligned and resistant to vibration — a common miss on unshrouded headers where bent pins show up after the board is assembled. The red insulation colour makes visual inspection of the mated pair straightforward on a populated board.
Through-Hole Termination with Press-Fit Option
Termination is listed as press-fit and solder — the through-hole pins (0.122" post length) can be wave-soldered or press-fit into a plated through-hole board. Press-fit avoids the thermal stress of reflow and is common in high-reliability backplane assemblies where rework is a consideration. The 2.54mm row spacing matches standard perf-board and prototyping grids, which simplifies layout for a first build.
