It uses the standard 0.100" (2.54mm) pitch on both rows and between rows — the classic DIP/IDC footprint that mates with any standard 0.100" receptacle or ribbon cable connector. Tin plating keeps the cost down but limits the connector to around 25–50 mating cycles, so this header is suited for internal harness connections that are mated once during assembly or infrequently in service.
BERGSTIK II is Amphenol's general-purpose unshrouded header family. The 86840-424HLF sits at the 24-position, dual-row, right-angle variant. The same series also includes straight (vertical) versions and single-row configurations — the key selection axis is orientation and position count. If your board layout calls for a right-angle header at 0.100" pitch with 24 circuits, this is the direct fit. A straight version (vertical mount) would change the mating axis to parallel with the PCB, which changes the harness routing.
