“D” Subminiature Connector Shields
METAL IMPREGNATED MATERIALS
MIL CONNECTOR GASKETS
Laird offers a broad range of EMI gasket materials to t the shell sizes of
standard MIL connectors.
• Gaskets are available in a wide range of materials that can provide
shielding or a combination of RF shielding and environmental sealing
• Standardized to t all MIL connectors
• Test results indicate shielding effectiveness of 100 dB or greater for
these connector gaskets

HOW TO SPECIFY
1. From Table below, match base part number to shell size used.
2. From Table 1, determine material code based on characteristics which best meet design requirements.
3. Insert material code in place of the XX from base part number.
Example: Base part number for shell size F in Table below is 8516-0210-XX; material code chosen from Table 1 is -57: part number is 8516-0210-57.
METAL IMPREGNATED MATERIALS
DIE-CUT GASKET
Oriented wire can be supplied as a die-cut gasket in various
congurations. Gasket sizes are available up to 9 in. (228,6
mm) X 36 in. (914,4 mm). Several of the most common die-cut
gaskets are for cable connectors and Sub-D connectors shown in
Figures 2a and 2b.
ELECTROMET IMPREGNATED
WOVEN WIRE AND EXPANDED METAL
ElectroMet impregnated wire mesh and expanded metal gaskets
are available in thin sheet form. EMI shielding is provided by
woven aluminum mesh or expanded metals. Pressure sealing is
provided by neoprene or silicone elastomer impregnated in the
mesh. Fluorosilicone is also available for specic applications that
require resistance to oils, hydraulic uids and hydrocarbon fuels.
Corner holes may be slotted
at Laird option
FIGURE 2A. CABLE CONNECTOR
FIGURE 2B. SUB-D CONNECTOR
Holes closer to edges than
2x material thickness will be
made as “u” slots at Laird
option
