Product details

40-position, 1.27mm pitch board-to-board header for parallel stacking

The right-angle through-hole orientation and 4-wall shroud with mounting flange make it a solid choice for parallel PCB stacking where mechanical stability and a defined mating depth are needed.

Pitch, position count, and mechanical fit for board layout

The mounting flange adds a screw-down option for extra retention in vibration-prone environments. Mating pin length is 0.130" (3.30mm) and the post length is 0.075" (1.91mm), which together define the stack height between boards.

Frequently asked questions

What is the mating connector for 87402-120LF?

This header mates with a 40-position, dual-row, 1.27mm pitch board-to-board receptacle from the same Rib-Cage™ series. Confirm the receptacle part number against your assembly drawing — the 4-wall shroud requires a matching shroud or receptacle profile.
