6.2mm cell size Brass / Steel Honeycomb Waveguide Air Vents
Shielded Material
Honeycomb filters are utilised to obtain effective electromagnetic
shielding while assuring, at the same time, excellent airflow. The
filters may be provided in various materials, with or without
EMI/EMC frame and gaskets (and environmental sealing), ready for
installation.
In common, we distinguish it from its material, thickness, cell
hole size, outer size,
with or without frame.
We have Stainless Steel, Tin plate, Brass, even Aluminum materials.

Product features
the cut-off waveguide ventilation window is composed of hexagonal
honeycomb core material with frame.
On the premise of ensuring efficient ventilation, the principle of
high pass and low resistance of cut-off waveguide
is used to effectively shield electromagnetic wave. Generally
speaking, the cut-off principle of cut-off waveguide is:
l ≥ 5D (L: waveguide length, D: maximum diameter of waveguide section),
Therefore, the shielding effectiveness of
the cut-off waveguide ventilation window depends on the length of
the waveguide (i.e. the thickness of the honeycomb
core and the size of the aperture of the honeycomb core).
Honeycomb window guide through the strom is widely used in the
field of electromagnetic shielding,
shielding cabinet for shielding room air circulation and good
shielding performance. Depending on the
pore size and thickness, the shielding effectiveness can be
improved.
