Board-to-Cable Header with Positive Retention
The 5499374-4: Shrouded on all four sides with a keying slot and mounting flange, the header prevents mis-mating and provides mechanical stability during assembly. The 30 µinch gold or gold-palladium plating on the mating face supports repeated mating cycles in field-service equipment — the contact interface stays corrosion-resistant through hundreds of insertions.
Sourcing and Lifecycle Position
The base product number 5499374 covers the family; this variant carries the 20-position, gold-mating, short-eject configuration.
Mates with AMP-Latch receptacles that accept 0.100-inch pitch ribbon cable or discrete wires. The solder tails are 0.155" (3.94 mm) long, tin-plated — suitable for standard through-hole soldering on a 1.6 mm PCB. All 20 positions are loaded; the keying slot and mounting flange orient the header during board assembly, and the short eject hooks clear the receptacle latch without interference.
