A built-in board guide aligns the two halves during assembly, protecting the fine-pitch contacts from shear damage. ## Selecting the Stack Height for Your Board Pair This plug mates with its FH receptacle at any of four heights: 6mm, 10mm, 14mm, or 18mm. The height is determined by the receptacle variant you pair it with, not by the plug itself. If your board stack calls for a 10mm gap, for example, you select the 10mm receptacle from the same FH family. The plug's 5.59mm height above board leaves room for the receptacle to engage within the chosen stack. ## Contact Plating and Surface-Mount Termination","metaTitle":"TE 2-5179230-3 Free Height Plug, 80-pos, 0.80mm pitch","metaDescription":"TE Connectivity Free Height (FH) series plug, 80 positions, 0.80mm pitch, gold-plated contacts, SMT.
