Soli-D Series connectors are professional quality connectors recom-
mended for use in sheltered, non-corrosive indoor or outdoor environ-
ments having normal ventilation, but without temperature or humidity
controls. This crimp removable contact connector will meet the
Performance Level Two requirements of IEC 807-3.
Soli-D Series connectors utilize precision machined contacts with
closed barrel, crimp terminations. The female contact features the
Robi-Contact open entry design. Other contact terminations such as
solder cup and printed board terminations are also available. The
removable contact feature provides for rapid assembly and permits
contact repairs on wiring changes.
Five standard contact variants are offered in arrangements of 9, 15,
25, 37 and 50 contacts. Soli-D Series connectors are mateable and
compatible with all D-Subminiature connectors conforming to IEC 807-
2, IEC 807-3 and MIL-DTL-24308.
A wide assortment of cable support hoods and locking systems is
available from stock.
Soli-D Series connectors conform to EIA RS 232 and RS 449, and
CCITT X.24 interface connection requirements.

REELS FOR AUTOMATIC PNEUMATIC CRIMP TOOLS
Contacts may be supplied in plastic carriers, packaged in reels holding 2,000 con-
tacts for use with the automatic pneumatic crimp tools, catalog part number 9550-1.
The same type carrier is used for both male and female contacts.
All male and female crimp contacts can be ordered in reels by adding letter “R” after
the contact part number, such as MC7526DR for a male contact and FC7520DR for
a female contact.
