Shielded Metal Wire Mesh Products from MAJR Products
One common product you will find when dealing with EMI shielding is metal wire mesh. But what is metal wire mesh and what does it do? Metal wire mesh is a strand or wire knitted together creating a structure of woven and knitted shielding material. Different types of metal wire mesh include non-hardenable types, hardenable…

What is a Honeycomb Waveguide Panel Shielding honeycomb waveguide panels let airflow into and out of an EMI/RFI shielded enclosure. The entering fresh air may be either cooled, heated, or at ambient temperature depending on the shielded enclosure environment and contents. For electronic equipment, the primary reason for airflow is usually to cool electronics; if…
