2-position, 5.08 mm pitch — industrial power or signal pair
The 2-917337-2 is a 2-position, single-row header from TE's Dynamic D-3200 series, on a 5.08 mm pitch. That pitch is wide enough for 600 V rating and easy routing on a 2-layer board, but the 2-position count means this is for a single circuit pair — a power feed, a sensor loop, or a discrete signal line.
Board lock and gold plating — field-fit reliability
On a 2-position part the lock is less about mass retention and more about keeping the header square to the board during assembly — a crooked header means a bad mate.
