The spring loaded Microminiature Low Profile Interposer (MLPI Series) is designed for demanding applications where space and height are limited but high performance is essential, in particular board-to-board stacking connections in defense electronics. 

Available in 30, 60, 90 and 120 positions with 1 mm pitch as standard and with 4 mm and 6 mm board to board height options, these high density connectors offer a space saving solution that does not require any mating counterpart. They are the only standard platform available that can fully support mixed signal operation for DC, RF and digital signal transmission in one solution, simultaneously if needed, which makes them adaptable to any application requiring high reliability performance and signal integrity.
