Product details

44-Position Dual-Row Breakaway at 0.100" Pitch

The 77317-112-44LF: This BERGSTIK header packs 44 positions in two rows spaced 0.100" apart, with all positions loaded — no blank spots to mislead assembly or probing.

Gold GXT Mating Face, Tin Tails — 3 A per Contact

Rated 3 A per contact across all 44 positions.

Unshrouded Breakaway — No Polarization Key

Unshrouded headers expose the full pin length for direct probing or manual wiring, but lack the polarization ramp of a shrouded header — the mating receptacle must be keyed or the board layout must prevent reverse insertion. The breakaway design means individual pin sections can be snapped apart for custom position counts, though this 44-position variant ships fully populated in a bag.
