The '30 S' in the description indicates a 30 µinch selective gold plating on the mating area, which gives it a solid cycle life for repeated connect-disconnect in a harness. The friction lock holds the mating receptacle in place against light vibration, but it's not a secondary lock — for high-vibration environments you'd want a TPA or a positive latch.","metaTitle":"Molex 41791-0849 KK 156 Header 2-Circuit 3.96mm Pitch","metaDescription":"Molex 41791-0849 KK 156 header assembly, 2 circuits, 3.96mm pitch, friction lock, ROHS3 compliant.
