Locking Ramp and Shrouded Protection
The 4-794626-0: The 4-wall shrouding surrounds the pins on all sides, guiding the receptacle into alignment and protecting the male contacts from damage during handling or blind mating.
The mating face carries 30 µinch gold over nickel — a plating grade that supports repeated connect/disconnect cycles without corrosion or wear-through. The solder tails are tin-plated (100 µinch) for reliable solder wetting.
SMT Right-Angle Mounting and Board Lock
The integrated board lock anchors the header during reflow and provides mechanical resistance to shear forces from the cable harness, preventing lifted pads in service.
