Densi-D Series connectors are Military/Industrial quality, high densi-
ty rectangular connectors designed for use in sheltered, mildly corro-
sive environments having a wide range of temperature, pressure and
humidity changes. These crimp removable contact connectors are
qualified to MIL-DTL-24308 and MIL-C-39029.
Densi-D Series connectors utilize precision machined contacts with
closed barrel crimp terminations, solder cup terminations, straight and
90° printed board mount.
All female contacts are of closed entry
design, featuring a fluted stainless steel shroud.
Six standard contact variants are offered in arrangements of 15, 26,
44, 62, 78 and 104 contacts. Densi-D Series connectors are mateable
and compatible with other high density D-Subminiature connectors
conforming to MIL-DTL-24308.
A wide assortment of mounting spacers, cable support hoods and
locking systems is available from stock.
