Product details

Connector Identity and Series Fit

The 2-178294-5: The connector is a Board to Board or Cable style, meaning it mates with a receptacle on a wire harness or another board — not a panel-mount or free-hanging plug. Full 4-wall shrouding protects the tab contacts during mating and prevents pin damage in blind-mate or vibration-prone installations.

Mounting and Orientation for Board Fit

Through-hole right-angle mounting means the header sits parallel to the PCB — typical for board-edge applications where the cable exits perpendicular to the board, saving z-height inside the enclosure. Contact length after post is 0.150" (3.81mm) — standard for through-hole solder joints on typical 1.6mm PCBs.

Packaged in bulk, so no tape-and-reel handling cost for through-hole assembly lines.

Frequently asked questions

What is the pitch of 2-178294-5?

The mating pitch is 0.150" (3.81mm) — wider than the common 2.54mm, so verify your board footprint matches this spacing.

Is 2-178294-5 a shrouded header?

Yes, it has a shrouded 4-wall design that protects the tab contacts during mating and prevents misalignment.
