The 75869-104RLF: The 4-wall shrouding and keying slot physically block a reversed or offset cable plug from seating, which saves rework time on the line. In a panel or enclosure where the header is recessed, the 0.377" (9.57 mm) insulation height clears most bezel cutouts.
Mating Surface and Contact Reliability
GXT is Amphenol's enhanced gold alloy, harder than pure gold – it resists adhesive wear through repeated insertions. For a harness that sees quarterly field disconnect, that plating grade supports well over a hundred mate cycles before the base metal is exposed. The post tails are tin-plated – tin wets well in wave solder and is compatible with lead-free SAC alloys. The 78.7 µinch (2.00 µm) tin thickness on the post meets the IPC Class 2 minimum for solder-joint reliability.
