Micro Edgeboard - .050" Contact Spacing
MEB
The Micro Edgeboard (MEB) connector series
provides a combination of high density and
high reliability for applications in airborne and
space systems, computers and peripherals, and
industrial /commercial control systems. This
series incorporates the proven
MICROPIN
TM
/MICROSOCKET
TM
contact. This con-
tact has an outstanding record of high
reliability and millions of contacts are in use in
various applications where electrical
interconnects are used.
The MEB has machined aluminum shells for
ruggedness, diallyl phthalate insulator for top
electrical performance and a 36-position
polarization key system to prevent cross plug-
ging. Contacts are on .050 (1.27) center
spacings. A variety of termination types are
available, including 90˚ or right angle pigtails
for multi-layered P.C. boards, "coke bottle”
termination for double-sided P.C. boards.
Harnessing capability is also available for both
pin and socket sides.
The MEB, including the SBR 90˚ or right angle
variation available for multi-layer boards, can
be mounted on the female (daughter) side of
double or single-sided P.C. boards. The mating
male (mother) board side can have the
terminations formed to meet the application
demands.
Conforms to MIL-C-55302/120 thru 123. (not
