Rhapso-D Series connectors are Military/Industrial quality rectangu-
lar connectors designed for use in sheltered, mildly corrosive environ-
ments 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, and will meet the performance
requirements of IEC 807-3, Performance Level One.
Rhapso-D Series connectors utilize precision machined contacts
with closed barrel, crimp terminations. The female contact features a
rugged closed entry design contact with stainless steel shroud. A
“Robi-D Open Entry” female contact is also available.
Six standard connector variants are offered in arrangements of 9,
15, 25, 29, 37 and 50 contacts. Rhapso-D Series connectors are mate-
able and compatible with all D-Subminiature connectors conforming to
MIL-DTL-24308, IEC 807-2 and IEC 807-3.
A wide assortment of cable support hoods and locking systems is
available from stock.
Rhapso-D Series connectors conform to EIA RS 232 and RS 449,
and CCITT X.24 interface connection requirements.
