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 MICROPINTM/MICROSOCKETTM 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-

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 qualified)
