USB Port 4 Pin Connector, Part Number 5068-EA
Usage: Multi-use, hot plug-and-play
For shielding and grounding, conductive foam is an excellent
material for Input/Output (I/O) applications. Conductive Foam has
excellent X, Y, and Z-axis conductivity and shielding effectiveness
over 90 dB for a wide range of frequencies. Laird Technologies can
help design custom gaskets to your specifications using a sketch,
electronic drawing or your actual equipment.
Shown here are some examples of I/O gaskets designed for
specific applications.

Pressure-Sensitive Adhesive (PSA) and Extended Release
Liner (ERL) can be applied in parallel with the long
edge of the gasket.
the gasket to a cutout should match or exceed the thickness
of the part and be greater than 0.060” (1.5 mm). In most
cases, a slot can be used in place of a hole.
