Contact system and mating interface
The 1-103904-3 is the 14-position member of TE's AMPMODU MTE header line, a single-row shrouded header with a latch holder for positive retention. Mating contacts are gold-plated (30.0 µin / 0.76 µm) over a brass square pin — the gold layer supports repeated mating cycles in corrosive environments. The through-hole right-angle orientation places the pin parallel to the board, suited for edge-mating with the AMPMODU MTE receptacle.
Board retention and housing
A board lock and keying slot are integrated into the 4-wall shrouded housing, molded from UL94 V-0 thermoplastic. The board lock holds the header during wave solder; the keying slot prevents mis-mating with unkeyed receptacles in multi-connector panels.
