Harmo-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 fixed contact
connectors are qualified to MIL-DTL-24308 (see pages 84-94 for listing)
and meet the performance requirements of IEC 60807-2, Performance
Level One.
Harmo-D series connectors utilize precision machined contacts which
are fixed within the connector body. The female contact features
Positronic’s unique PosiBand closed entry design, see page 1 for details.
Five standard connector variants are offered in arrangements of 9, 15,
25, 37 and 50 contacts. Each connector variant is available with contact
terminations for solder cup, wrap post and straight and right angle (90°)
printed board mount terminations with Inch and Metric footprints.
Harmo-D series connectors are mateable and compatible with all D-sub-
miniature connectors conforming to IEC 60807-2, IEC 60807-3 and
MIL-DTL-24308.
A wide assortment of printed board mounting hardware, cable
support hoods and locking systems is available from stock.
