Board-to-Board Signal Header for Dense Routing
The Amphenol FCI 87901-464HLF is a 64-position, dual-row unshrouded male header from the BERGSTIK® II series, on the standard 0.100" (2.54mm) pitch. It carries 32 pins per row, making it a dense signal interconnect for parallel buses, I/O cards, or backplane mezzanine boards where every circuit needs a dedicated pin.
The 0.100" pitch matches standard breadboard and protoboard layouts — no custom footprint needed if your board uses 2.54mm grid spacing. For a board that gets assembled once and stays in an enclosure, the tin finish is fine.
