Board-Mount Orientation and Retention
The 4-794621-0: A board lock on each end anchors the part during reflow and takes shear load from the cable after mating. In a vibration environment — say, inside a panel or on a moving assembly — the ramp keeps the pair from backing apart.
The post finish is also tin at the same 100.0 µinch thickness, compatible with lead-free solder processes. The voltage ceiling is 250 V.
Housing Material and Temperature Range
The insulator is polyamide (nylon) rated UL94 V-0.
