Micro Edgeboard - .050" Contact Spacing

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

contact 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-

MEB

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
