Selective Population — 12 Positions, 8 Loaded
The 77312-483LF: This BERGSTIK® header carries 12 pin positions in a single row, but only 8 positions are populated with contacts. The remaining four cavities are empty — the buyer must verify their circuit count against the loaded positions, not the housing size.
Tin Plating — Cost-Effective for Low-Cycle Mating
Both the mating contact finish and the post finish are tin, with a thickness of 80.0 µinch (2.03 µm) on the mating side and 78.7 µinch (2.00 µm) on the post. Tin-on-tin is a reliable, low-cost interface for applications with infrequent mating cycles — think board-to-board within an enclosure that is assembled once.
