What this 50-position header does on your board
The 5-104069-2: Gold-plated mating contacts (30 µinch) handle moderate-cycle interconnects — think 100-200 mates over the product life. The 30 VAC rating and tin-plated solder tails (150 µinch) keep this a signal-level header, not a power bus.
Pitch, footprint, and board routing
At 0.050" pitch, the 50 circuits pack into a 1.27 mm grid — tight enough for dense signal routing but wide enough for standard PCB fab processes. Mating contact length is 0.125" (3.18 mm); post length is 0.100" (2.54 mm) — the post length sets the through-hole solder depth.
Mating and latch retention
In a vibration environment (automotive, industrial), the latch keeps the pair mated without secondary hardware.
