The Amphenol BERGSTIK® II 93939-152HLF is a 52-position, dual-row, unshrouded male pin header on the standard 0.100" (2.54mm) pitch. It terminates through-hole in a right-angle orientation, making it a fit for board-edge or parallel-to-PCB mating in a board-to-board stack. Rated 5A per circuit at 110V, with a UL94 V-0 black insulation housing.
The 52 positions across two rows (26 per row) with a 0.100" row spacing means the board footprint is about 2.6 inches long — a significant chunk of real estate, so confirm your board layout has the length before committing.
Gold Plating Grade and Current Rating — What Drives the Duty
The 30.0µin (0.76µm) gold on the mating interface is the feature that governs the real duty here, not the headline 5A per circuit. The tin post finish is standard for solder-joint reliability in the through-hole wave.
