The FCI 87185-104HLF is a 4-position, single-row unshrouded header from the BERGSTIK® II series, on the classic 0.100" (2.54mm) pitch. The 30.0µin (0.76µm) gold plating on the mating surface is specified for repeated mating cycles — the contact finish thickness is the deciding factor for reliability in field-service or test applications, not the headline 5A current rating.
The 1.043" (26.49mm) mating pin length gives plenty of reach through a receptacle housing for a secure connection; the 0.095" (2.41mm) solder post is sized for a standard 0.062" board thickness.
