The Amphenol 86840-432HLF is a 32-position unshrouded header from the BERGSTIK® II series, arranged in two rows on a standard 0.100" (2.54 mm) pitch. The contacts are square male pins with a 0.318" mating length and a 0.230" post length, both tin-plated — the mating finish is a thick 100.0 µin (2.54 µm) layer, which gives good durability for moderate-cycle applications without the cost of gold.
Rated 5 A per contact at 110 V, this header handles standard signal-level current — it is not a power interconnect, but the 5 A per circuit gives headroom for daisy-chained signals or low-power distribution across the 32 positions. The 0.100" row spacing matches the pitch, so the board footprint is a clean 0.100" grid — standard for prototyping and legacy bus architectures. The UL94 V-0 rated black insulation housing (0.190" standoff height) is suited for equipment inside an enclosure that requires a flame rating.
