Holland Shielding Systems B.V. is one of the best known RFI/EMI filter manufacturers in the market. We offer a complete selection of RFI signal, power and data transmission filters and EMI filters for nearly every application including powerline filters, signal line filters and facility filters. Holland Shielding Systems B.V. is also capable of designing custom EMI/RFI filters for your specific application.

Below you see an prefabricated filterplate with high preformance powerfilters installed (up to 120 dB). For the cable passaging of digital signals like ISDN and UTP (internet/network connections) etc.
We manufacture signal filters, for even higher preformance we can provide a system which uses optical technology and waveguide passage.
This allows you to monitor your faraday cages using a UTP network connection and a regular laptop or PC.

System also available with a battery convertor, if there is no
electric power available in the cage.

Shielded power and telephone filter.
These are medium preformance power filters,
information about high preformance filters on request.
