80-position signal header at 1.27mm pitch
The 5-104666-5: Its 0.050" (1.27mm) pitch packs 80 circuits into a compact footprint, typical for telecom line cards, medical imaging boards, or automotive control modules where routing density matters.
What the 30VAC rating means for your circuit
Rated at 30VAC, this header is a signal-level interconnect — not for power distribution. Use it for low-voltage logic, data buses, or sensor lines where the per-contact current stays below a few amps.
Mating half and latch details
This shrouded header mates with AMPMODU System 50 receptacles that accept the same 0.050" pitch and dual-row layout. The insulation height of 0.390" (9.91mm) and mating contact length of 0.125" (3.18mm) set the mated stack height; confirm the receptacle's depth for your board-to-board spacing budget.
