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.
