Board-to-board or cable breakaway header
The 77313-824-52LF: Mating contacts are gold or gold GXT plated (15.0µin) over phosphor bronze; the posts are tin-plated (78.7µin). The unshrouded header mates with a push-pull fastening and is rated 3A per contact.
Pitch, row spacing, and board footprint
Both the mating pitch and row spacing are 0.100" (2.54mm), giving a standard dual-row footprint that matches legacy 0.100" grid layouts. The 0.114" (2.90mm) post length suits typical through-hole boards up to 1/16" thick.
