20-position, 1.27 mm pitch unshrouded header for board-edge signal routing
The 6-104186-1: This AMPMODU System 50 header packs 20 circuits into a single row at 0.050" (1.27 mm) pitch — a footprint that suits dense board-edge signal routing where every millimeter of PCB real estate counts.
Unshrouded push-pull fastening with gold-on-tin contact system
Compared to a shrouded header like the 1-1871673-2 (2.50 mm pitch, 4 positions, tin mating finish), this part offers a denser pitch and gold mating finish for higher signal density and better corrosion resistance, but lacks the board lock and detent lock of that peer.
