Product details

Board-to-wire fit: 7 positions, 2.50 mm pitch, right-angle

Rated 4.2 A per circuit at 250 VAC — the tin-on-tin contact finish (mating and post) keeps contact resistance low for general-purpose signal and moderate power duty, though tin limits mating cycle life compared to gold.

This header mates with Economy Power 2.5 series receptacles (crimp-style housings) for wire-to-board connections.
