26-position, 2.54mm pitch — board footprint and current budget
The 5102321-6: The 1A per contact rating at 250VAC sets the per-circuit current ceiling; in a typical signal harness the temperature rise stays well within the UL94 V-0 housing limit.

TE Connectivity AMP-Latch series, 5102321-6, board-to-cable/wire header, 26 positions, 2 rows, 0.100" (2.54mm) pitch, shrouded 4-wall, through-hole solder termination, gold or gold-palladium mating finish, rated 1A per contact at 250VAC.
