20-pin AMP-Latch header for ribbon cable termination
The 5499206-4 is a 20-position, 2-row shrouded header from the TE AMP-Latch series, designed to mate with standard 0.100-inch (2.54mm) pitch IDC ribbon cable sockets. The long latch lock/eject hooks secure the mating cable connector and allow tool-less disengagement from the board.
Gold mating finish for repeated connect cycles
The mating contacts carry a gold or gold-palladium finish with a thickness of 30.0 microinches (0.76µm), supporting repeated mating cycles without degradation. The post tails are tin-plated (100.0 microinches / 2.54µm) for reliable solder wetting in through-hole assembly.
Board layout and termination notes
Through-hole mounting with 0.110-inch (2.79mm) post length and 0.639-inch (16.23mm) overall contact length; the 0.549-inch (13.94mm) insulation height provides clearance for the cable strain relief. The keying slot and mounting flange prevent mis-mating and add mechanical stability to the board interface.
