The Amphenol 87185-411HLF is an 11-position, single-row, unshrouded BergStik® II header on the standard 0.100" (2.54mm) pitch. The 5 A per-contact rating and 110 V voltage limit suit it for signal-level and light power distribution inside equipment enclosures.
The 11-position count is exact: a 10- or 12-position header won't line up with the mating housing or the PCB footprint. The 5 A per-contact rating at the 2.54mm pitch is typical for signal interconnects and low-current power rails. The 110 V rating is conservative for the pitch — the creepage distance between adjacent pins on 0.100" centers supports higher voltage, but the rating reflects the UL recognition level for the housing material. The black UL94 V-0 housing self-extinguishes within 10 seconds, which is the baseline requirement for any connector that lives inside a piece of equipment with a flammability certification.
This is an unshrouded header — no polarization ramp or keying feature.
