What this connector is
The Amphenol ICC 87900-112HLF is a dual-row male pin header in the BERGSTIK II series, built for board-to-board stacking at 0.100" (2.54mm) pitch. Twelve square phosphor bronze contacts run the full depth of the housing, all loaded, with gold or Gold GXT plating at 30.0µin (0.76µm) on the mating interface. The push-pull fastening holds the mated pair together without hardware; the unshrouded profile keeps it compact but means the board-layout engineer needs to account for correct polarization when the mating half has keying features.
Key ratings for your selection decision
At 5A per contact the 87900-112HLF sits comfortably above the signal-level ratings common in this pitch class — it will carry power bus lines or actuator drives without derating concerns at room temperature. The 110V rating covers most low-voltage logic and control rails. The 30.0µin gold plating is the meaningful differentiator: that thickness handles repeated mating cycles far better than standard tin, so in applications where the board gets serviced or reconfigured, fretting resistance is a real advantage rather than a spec-sheet claim.
Board layout and stack fit
The UL94 V-0 rating on the black housing clears the flammability threshold for enclosed industrial equipment — a common requirement in factory-floor instrumentation and control enclosures.
What it mates with
The 87900-112HLF is a male pin header — it needs a matching dual-row receptacle or IDC socket housing from the BERGSTIK II family (or a compatible pitch-equivalent from another series). The unshrouded profile means the polarization and keying are entirely governed by the mating half; if the application is vibration-prone, confirm the receptacle has polarization keys or latching hardware that positively locks the pair. The push-pull fastening on this header is sufficient for static board-stack or lab interconnects; for production equipment with repeated servicing, a latch-equipped receptacle is the safer pairing.
