TE Connectivity 0.8mm Free Height (FH) Vertical Board to Board Plug Connectors 0.8mm Free Height (FH) board to board or mezzanine SMT plug connectors for use in parallel board stacking applications. These Free Height (FH) mezzanine connectors have a high density subminiature packaging with a .031mm centerline spacing making it possible to save more than 50% space on the PCB compared to 1.27mm centerline connectors. The contacts of these 0.8mm Free Height (FH) connectors have a bellows type spring design that is resistant to scooping and stubbing when the connector is mated and unmated and offers a reliable electrical connection. These 0.8mm Free Height (FH) plugs feature polarization to ensure accurate mating and have PCB postioning bosses for accurate placement on the PCB. A range of board to board stacking heights from 5 to 16mm can be achieved by mating these 0.8mm FH plug with different board mount receptacles. Part numbers 5177984-X and 5177986-X are 5mm FH vertical plugs for 5, 9 and 13mm stacking heights Part numbers 5179029-X and 1-5177986-X are 6mm FH vertical plugs for 6, 10 and 14mm stacking heights Part numbers 5179030-X and 2-5177986-X are 7mm FH vertical plugs for 7, 11 and 15mm stacking heights Part numbers 5179031-X and 3-5177986-X are 8mm FH vertical plugs for 8, 12 and 16mm stacking heights
