The Amphenol FCI 86840-172HLF is a 72-position, dual-row unshrouded header from the BERGSTIK® II series, on 0.100" (2.54mm) pitch with matching 0.100" row spacing. All 72 positions are loaded, giving a dense 36-per-row footprint for high-circuit-count signal distribution.
Rated 5 A per circuit at 110 V, which is typical for a 0.100" pitch signal header — the current per pin is not limiting for logic-level or low-power analog signals, but the 110 V ceiling gives enough headroom for 48 V telecom rails or 24 V industrial buses without derating.
Phosphor bronze contact material with a square pin cross-section. The black insulation is rated UL94 V-0.
