6.35 mm pitch, 2-position power header
The 1-1747277-2: The 0.250" (6.35 mm) pitch gives you room to route heavier traces between pins without crowding the board. Rated 600 V, it handles line-voltage industrial control circuits, not just low-signal logic. The gold mating finish (15.0 µin) supports repeated mate cycles in environments where tin would fret.
Through-hole mount with board lock
The board lock feature keeps the header seated during reflow and resists shear force from cable strain after mating. Housing is black thermoplastic, glass-filled polyester rated UL94 V-0.
