SGM
SERIES
HIGH DENSITY RECTANGULAR
CONNECTORS with
FIXED CONTACTS
SGM Series connectors are high reliability, high density, rectan-
gular connectors qualified to MIL-DTL-28748 specifications. The
SGM Series offers solder cup, wrap post and straight solder ter-
mination styles, and is intermateable with Positronic SMPL and
SGMC series connectors.
Thirteen connector variants, four through 75 poles, are offered.
Contact spacing is 0.094 inch [2.39mm] between centers, and
contact diameters are 0.030 inch [0.76mm], rated to five amperes
per contact.
A complete array of mounting, locking, polarizing and shrouding
accessories is available for the SGM Series. For details, see the
High Density Rectangular Connector Accessories section.
Ideal applications for the SGM Series are where low weight
and high density are requirements.
The high reliability of
“closed entry” female contacts insures numerous couplings of
the connector without substantial degradation of contact resis-
tance. SGM Series connectors are preferred for use in the
aerospace, avionics, telecommunications, instrumentation,
medical and robotics industries.
