What This Header Is
The Amphenol FCI 92634-442HLF is the 42-circuit member of the BERGSTIK II dual-row header series — an unshrouded push-pull male board-to-board header terminated by through-hole solder to a daughter card or backplane. The 0.100" (2.54 mm) pitch and square pin profile place it in the most widely used through-hole header grid in industrial controls, instrumentation, and automation equipment, where the right-angle orientation allows the connector to sit flat against the board surface and accept a mating receptacle from the same face.
