The board guide is a molded alignment feature that engages with the receptacle's guide posts before the contacts touch, preventing stubbing on the fine 0.80 mm pitch. No through-hole anchors; the SMT pads alone carry the mechanical retention, so the mated stack relies on the guide system for shear resistance during handling or vibration.","metaTitle":"TE 5179031-4 Free Height (FH) Plug, 100 Pos, 0.80 mm Pitch","metaDescription":"TE 5179031-4 Free Height (FH) plug, 100 positions, 0.80 mm pitch, gold contacts.
