The FCI / Amphenol 92417-140HLF is a 40-position, dual-row BergStik® II unshrouded pin header. It sits in the standard 0.100" (2.54mm) pitch grid, with the same 0.100" row spacing, making it a drop-in fit for standard perfboard and 2.54mm-pitch receptacles.
The 0.100" (2.54mm) pitch and row spacing are the industry-standard grid — this header mates with any standard 0.100" pitch IDC socket or crimp receptacle housing (e.g., the matching BergStik II or similar dual-row 0.100" receptacles). The 40 positions, fully loaded across two rows, match a 40-conductor ribbon cable or a 40-position receptacle.
The unshrouded, push-pull design means no polarization key — the board layout and receptacle orientation are the only mis-mating protection.
