Melo-D Series connectors are professional quality connectors rec-
ommended for use in sheltered, non-corrosive indoor or outdoor envi-
ronments having normal ventilation, but without temperature or humid-
ity controls. These fixed contact connectors meet the dimensional and
performance requirements of IEC 807-2, Performance Level Two.
Melo-D Series connectors utilize precision machined contacts which
are fixed within the connector body. The female contact is an open
entry design contact, precision machined of high tensile phosphor
bronze.
Six standard connector variants are offered in arrangements of 9,
15, 25, 29, 37 and 50 contacts. Each Melo-D connector variant is avail-
able with contact terminations for solder cup, wrap post, and straight
and 90° printed board mount terminations featuring a choice of three
printed board footprints. Melo-D Series connectors are mateable and
compatible with all D-Subminiature connectors conforming 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.
Melo-D Series connectors conform to EIA RS 232 and RS 449, and
CCITT X.24 interface connector requirements.
