MD / ED SERIES
Melo-D and Euro-D Series connectors are professional quality connec-
tors recommended for use in sheltered, non-corrosive indoor or outdoor
environments having normal ventilation, but without temperature or humid-
ity controls. These fixed contact connectors meet the dimensional and per-
formance requirements of IEC 807-2, Performance Level Two.
Melo-D and Euro-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 available
with contact terminations for solder cup, wrap post, and straight and 90°
printed board mount terminations featuring a choice of three printed board
footprints. Each Euro-D connector variant is available with contact termi-
nations for solder cup, wrap post and straight and 90° printed board mount
terminations per standard European metric footprints. Melo-D and Euro-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 and Euro-D Series connectors conform to EIA RS 232 and RS
449, and CCITT X.24 interface connector requirements.
