The 0.430\" (10.92mm) mating pin length gives enough reach to engage a standard socket strip, and the 0.200\" (5.08mm) post length suits a typical 1.6mm PCB. ## Plating and Duty","metaTitle":"Amphenol BERGSTIK II 79821-424HLF, 24-Pos 0.100\" Header","metaDescription":"Amphenol BERGSTIK II 79821-424HLF: 24-position, 2-row, 0.100\" (2.54mm) pitch unshrouded header.
