This The Double Density D connector is available in the insert area. The Double Density D connector can reversal of positions, and the chamfered-entry of the five popular shell and insert sizes accommodating up thus accommodate up to 100 contacts instead of 50. sockets, assures positive mating even under severe to 100 contacts. These connectors mate exclusively misalignment conditions. The contacts are retained with other Double Density D connectors.
