Right-angle header for board-edge power distribution
The 3-350942-0 is a 2-position, single-row, right-angle through-hole header from TE's Universal MATE-N-LOK series. The 6.35mm pitch and 12A per-circuit rating at 600VAC suit this header for power distribution on a PCB where you need a rugged, field-serviceable interconnect.
12A power path with gold contact interface
Each phosphor bronze contact is rated 12A continuous at 600VAC.
A common cross-shop is the 1318699-3, a 12-position, 4-row, 4.20mm-pitch header with 5A per contact and 250VAC rating. The 3-350942-0 carries a wider 6.35mm pitch and higher per-contact current (12A vs 5A), but only 2 positions in a single row. The 1318699-3 uses a latch lock instead of a locking ramp, and its gold plating is thinner (3.00µin vs 30.0µin).
