Free Height Stacking Connectors

Stacked Application Design

These versatile connectors are useful for downsizing applications that require parallel stacked printed circuit boards (PCBs). They provide a range of position sizes from 40 - 440 positions in contact pitches of .5, .6, .8, and 1.0mm, and by mating various combinations of vertical plug and receptacle housing heights, board-to-board stack heights from 4-20mm can be achieved in 1mm increments.
