Rhapso-D series connectors are military quality connectors
designed for use in sheltered, mildly corrosive environments having a
wide range of temperature, pressure and humidity changes. Applicable
crimp removable contact connectors are qualified to MIL-DTL-24308
and SAE AS 39029 (see pages 84-94 for listing), and will meet the per-
formance requirements of IEC 60807-3, Performance Level One.
Rhapso-D series connectors utilize precision machined contacts
with closed barrel, crimp terminations. The female utilizes Positronic’s
unique PosiBand closed entry system, see page 1 for details. “Robi-D”
open entry female contacts are 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 60807-2 and IEC 60807-3.
A wide assortment of cable support hoods and locking systems is
available from stock.
