The Amphenol BERGSTIK II 87052-424HLF is a 24-position, dual-row unshrouded board-to-board header on the standard 0.100" (2.54 mm) pitch.
The 0.100" pitch is the bread-and-butter grid for prototype boards and standard perfboard — your PCB footprint is a straightforward 2.54 mm matrix, and the dual-row layout with 0.100" row spacing keeps routing density predictable. At 5 A per circuit, this header handles modest power distribution (think signal + local rail) but the tin-on-tin contact interface limits you to about 50 mating cycles before the plating wears; it's a production-assembly connector, not a frequent field-service disconnect. The unshrouded design means there's no keying ramp to guide the mating half — the receptacle alignment depends entirely on the board layout and the solder joint's shear strength, so the through-hole tails are your mechanical anchor.
