The Amphenol BERGSTIK II 87185-112HLF is a 12-position, single-row, unshrouded male pin header on the standard 0.100" (2.54 mm) pitch. It is a board-to-board interconnect — the pins mate with a matching receptacle housing, typically a BergStik or similar 0.100" pitch socket strip. The through-hole solder termination and square pins make it a direct fit for breadboard, perfboard, or any PCB laid out on 0.100" centers. Rated 5 A per circuit with a 110 V voltage rating, it handles signal and light power duty in prototype, test equipment, and production assemblies where the unshrouded profile keeps the footprint low.
What the key ratings mean for your fit
The 0.100" (2.54 mm) pitch is the classic DIP/breadboard spacing — your PCB footprint matches any standard 0.100" header receptacle or socket strip. The 12 positions are fully loaded, so every pin is present; if your BOM calls for 12 circuits, this is a one-to-one match. The 5 A per circuit rating is per-pin at the rated temperature rise — suitable for signal lines, logic power, and low-current loads, but not a bus-level power rail. The 30.0 µin (0.76 µm) gold or GXT plating on the mating surface gives this header a high cycle life — good for test fixtures, programming jigs, or any application where the connector sees repeated mate/unmate cycles. The unshrouded design means there is no keying or polarization: the mating receptacle must provide its own shroud and the assembler must align the pin row visually.
Mating and termination
This header mates with any standard 0.100" (2.54 mm) pitch receptacle or socket strip — the unshrouded pins insert into the mating housing's shroud. The push-pull fastening means there is no locking latch; the retention comes from the contact interference fit. The through-hole solder termination is a straight post, 0.095" (2.41 mm) long, for soldering into plated through-holes. The overall contact length of 1.238" (31.45 mm) includes a 1.043" (26.49 mm) mating length — the pins extend well above the housing for deep engagement with the receptacle.
