The 5-103908-1: The shrouded - 4 wall housing with a keying slot protects the male square pins and prevents mis-mating in multi-connector layouts — a common requirement when several headers sit side-by-side on a panel or PCB. Termination is listed as press-fit or solder — the same header can be pressed into a plated through-hole for solderless backplane assembly or wave-soldered in a conventional board.
Mating Half and Keying Details
This header mates with AMPMODU MTE receptacle housings that carry the matching latch. The keying slot in the shroud ensures the receptacle can only be inserted one way — a safeguard in panels where multiple 2-position headers are ganged together and a reversed mate would short the circuit. The insulation height of 0.535" (13.60 mm) gives the shroud clearance above the board surface — check the z-height budget if the mating receptacle sits in a tight enclosure.
