Harmo-D Series connectors are Military/Industrial quality rectangular con-
nectors designed for use in sheltered, mildly corrosive environments having
a wide range of temperature, pressure and humidity changes. These fixed
contact connectors are qualified to MIL-DTL-24308 and meet the perfor-
mance requirements of IEC 807-2, Performance Level One.
Harmo-D Series connectors utilize precision machined contacts which
are fixed within the connector body. The female contact features a rugged,
closed entry design contact with a stainless steel shroud.
Five standard connector variants are offered in arrangements of 9, 15, 25,
37 and 50 contacts. Each connector variant is available with contact termi-
nations for solder cup, wrap post and straight and 90° printed board mount
terminations with Inch and Metric footprints. Harmo-D Series connectors
are mateable and compatible with all D-Subminiature connectors conform-
ing to IEC 807-2 and MIL-DTL-24308.
A wide assortment of printed board mounting hardware, cable support
hoods and locking systems is available from stock.
Harmo-D Series connectors conform to EIA RS 232 and RS 449, and
CCITT X.24 interface connection requirements.
