SERIES 621 / 622 D-SUBMINIATURES
0.318 FOOTPRINT RIGHT ANGLE
The Edac Series 621 (Plug) and 622 (Receptacle) D-
Subminiature connectors are one of the most well-known
connector families in the world. These series feature the
standard 0.318 (8.08mm) footprint in the popular D-shell
sizes of 9, 15, 25, 37 and 50 contacts, and can be ordered
with optional ferrite filtering. They will mate with all other
industry-standard D-Sub connectors that are based on EIA
RS232, EIA RS449, and MIL-C-24308 standards. All con-
nectors feature a metal shell for EMI/RFI shielding and
have up to four prong board locks for superior retention to
the printed circuit board. Indents on the plug shell provide
grounding and additional mating retention. Grounding fea-
tures include top or bottom ground plates. All units are a
right angle design with printed circuit contacts.
