HIGH DENSITY RECTANGULAR
RIGHT ANGLE
PRINTED BOARD MOUNT CONNECTORS
SMPL Series connectors are high reliability, high density, rec-
tangular connectors meeting the performance requirements of
MIL-DTL-28748. Termination style is right angle printed board
mount. SMPL Series connectors are intermateable with
Positronic SGM and SGMC series connectors.
Twelve connector variants, four through 50 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 and polarizing acces-
sories is available for the SMPL Series. For details, see the
High Density Rectangular Connector Accessories section.
Ideal applications for the SMPL Series are where low weight
and high density are requirements. The high reliability of the
“closed entry” female contacts insures numerous couplings of
the connector without substantial degradation of contact resis-
tance. SMPL Series connectors are used in the aerospace,
avionics, telecommunications, instrumentation, medical and
robotics industries.
