2. ONE PIECE TYPE INSULATOR-
Including full range of D Subminiature accessories
glass-filled nylon material
thermoplastic internal shoulder snaps into a locking groove in the contact.
seven outer wiping surfaces assure electrical continuity even under severe
shock and vibration
flexible pin is recessed in insulator cavity and rugged socket is exposed
assure alignment during mating and prevent scooping
Retention Force: 8 lbs. min. initially, 4 lbs. min. after 10 cycle.

The Double Density D is a rectangular connector in
the popular D Subminiature shell configuratoin fea-
turing double the contact density in the same insert
area. The Double Density D connector can thus
accommodate up to 100 contacts instead of 50.
positions are reversed; the flexible Centipin™ con-
tacts are recessed in the insulator and the more
rugged Centisocket™ contacts are exposed. This
reversal of positions, and the chamfered-entry of
the sockets, assures positive mating even under
servere misalignment conditions. The contacts are
retained in the monobloc insulator by a resilient
internal shoulder that snaps into a locking groove in
the contact. The chamfered front of the contact will
not damage the internal shoulder in the insulartor.
Contacts are crimp removable type.
The Double Density D connector is available in the
five popular shell and insert sizes accommodating
up to 100 contacts. These connnectors mate exclu-
sively with other Double Density D connectors. A
wide range of accessories can be used, including
junction shells, potting cups, switching shells, guide
pin plates, and dust caps.
This double contact density is achieved by using
field-proven, highly reliable Centipin™/Centisocket™
contacts on .075 (1.91) centers, in the positive
contact alignment design. In this design contact
