TE Connectivity Free Height Series Straight Surface PCB Socket, 40-Contact, 2 Row, 0.8 mm Pitch Solder

0.8mm Free Height (FH) board to board or mezzanine SMT receptacle connectors for use in parallel board stacking applications. These Free Height (FH) mezzanine connectors have a high density subminiature packaging with a .031mm centreline spacing making it possible to save more than 50% space on the PCB compared to 1.27mm centreline 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) receptacles 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 receptacles with different board mount plugs.
