3-Position Power Header at 6.35 mm Pitch
The 1-641966-1: This Universal MATE-N-LOK header gives you three circuits on a 0.250" (6.35mm) pitch — wide enough to route 12 A per contact without crowding the board, and the 600 VAC rating covers most industrial control and appliance power rails.
How It Stacks Against a Sibling
Compared to the 1318699-3 (12-position, 4.20mm pitch, 5 A, gold plating), this 1-641966-1 trades position density for current capacity — 12 A per circuit vs 5 A, and a wider 6.35mm pitch that gives the board more room for power traces. The tin plating on 1-641966-1 is adequate for moderate mating cycles; the gold plating on 1318699-3 buys you higher cycle life in corrosive environments.
