Soli-D series connectors are professional quality connectors rec-
ommended for use in sheltered, non-corrosive indoor or outdoor
environments having normal ventilation, but without temperature or
humidity controls. This crimp removable contact connector will meet
the Performance Level Two requirements of IEC 60807-3.
Soli-D series connectors utilize precision machined contacts
with closed barrel, crimp terminations. The female contact fea-
tures the Robi-Contact open entry design. Other contact termina-
tions such as solder cup and printed board terminations are also
available. The removable contact feature provides for rapid
assembly and permits contact repairs or wiring changes.
Five standard contact variants are offered in arrangements of 9,
15, 25, 37 and 50 contacts. Soli-D series connectors are mate-
able and compatible with all D-subminiature connectors conform-
ing to IEC 60807-2, IEC 60807-3 and MIL-DTL-24308.
A wide assortment of cable support hoods and locking systems
is available from stock.
