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
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

The Centi Line - .075" Contact Spacing
The Cannon Centi connectors are especially
suitable for commercial applications such as
computers, instrumentation, communications
and audio equipment. They are available in D
subminiature size metal shell rectangular,
plastic shell rectangular and strip configurations.
All Centi connectors use the reliable twist pin
contact design in a 5 amp version terminated
on .075 (1.91) and .100 (2.54) centers. The
Centi contact is crimp removable, connectors
are available for customer assembly. Standard
crimp and assembly tools are available.
The twist pin contact is recessed within the
insulator housing while the rugged cylindrical
socket is exposed. When the connector halves
are mated, the chamfered sockets guide the
pins into positive alignment. The CentipinTM
contact, now under compression, forms a
multi-point contact with the CentisocketTM to
provide a high degree of reliability.
Standard Data
• Contact rating: 5 amps max, except BR
Series (2 amps max.)
• Contact retention: Crimp snapin/removable.
• Minimum contact centers: 0.075 (1.91).
• Contact materials and finish: Copper alloy,
gold- plated per ASTM B488, Type II, Code
C, Class 1.25.
• Wire sizes: #22 thru #26 AWG, stranded or
solid.
• Contact termination: Multiple indent crimp.
• Mating/unmating force: 12 oz. per contact,
max.

Double Density D - .075" Contact Spacing
2D
The Double Density D is a rectangular connector in
the popular D Subminiature shell configuration
featuring double the contact density in the same
insert area. The Double Density D connector can
thus accommodate up to 100 contacts instead of
50.
This double contact density is achieved by using
field-proven, highly reliable CentipinTM/CentisocketTM
contacts on .075 (1.91) centers, in the positive contact alignment design. In this design contact
positions are reversed; the flexible CentipinTM
contacts are recessed in the insulator and the more
rugged CentisocketTM contacts are exposed. This
reversal of positions, and the chamfered-entry of the
sockets, assures positive mating even under severe
misalignment conditions. The contacts are retained
in the monobloc insulator by a resilient internal
shoulder that snaps into a locking groove in the
contact. The chamfered front of the contact will not
damage the internal shoulder in the insulator.
Contacts are crimp removable type.
The Double Density D connector is available in the
five popular shell and insert sizes accommodating
up to 100 contacts. These connectors mate exclusively with other Double Density D connectors. A
wide range of accessories can be used, including
junction shells, potting cups, switching shells, guide
pin plates, and dust caps.
