    Designed to retain PCBs in rugged, heavy shock and high vibration environments commonly found in Military and Defense and commercial aerospace systems. In additional to PCB retention, Card and Wedge Loks also aid in thermal transfer from the PCB to the cold wall via conduction, by improving the interface between the PCB and the chassis rail.


    The Series 250 features a larger profile and is better suited to accommodate heavier Board Module Assemblies.
