The Amphenol BERGSTIK® 75844-118-26LF is a 26-position, dual-row unshrouded breakaway header on a standard 0.100" (2.54mm) pitch.
The 0.100" pitch and 0.100" row spacing define a standard 0.100" x 0.100" grid footprint. This is a common pattern for prototyping and legacy bus architectures — the board layout matches a wide range of ribbon-cable IDC receptacles and mating socket headers. The 0.120" (3.05mm) solder post length is sized for a typical 0.062" PCB; for thicker boards, verify the post protrusion clears the solder joint.
The BERGSTIK® series is a broad family; the 75844 base number identifies this as a dual-row, straight, through-hole configuration with gold GXT™ plating.
