Flange profile

If EMI protection and simultaneous light flow are required, MTC offers a cost-effective solution with various types of honeycomb filters.

Different materials such as , steel, or brass are available. These metals are formed thin, laminated and then drawn into a honeycomb structure.

In order to achieve the best characteristics, the honeycomb filters can also be designed as double honeycombs, in which two honeycomb structures are placed offset behind each other.

Various frame types also allow direct and precise mounting on the application.

  • Available with integrated or separate EMI/RFI gasket
  • Different thicknesses of honeycomb sheets and diameter of cell
  • Available with flange profile or U-shape vent panel
