How to select the appropriate EPS cabinet door shielding gasket?

Selecting the right shielding gasket for the EPS cabinet door is crucial for ensuring the overall shielding effectiveness of the cabinet. Selection requires comprehensive consideration of the following:

1. Shielding Effectiveness (SE): Based on the EMC standard level and maximum operating frequency required by the system, select a gasket with the appropriate SE value (SE curves for different frequencies are usually provided).

2. Environmental Adaptability: Consider the temperature, humidity, presence of oil, salt spray, or ozone in the cabinet's environment, and select a gasket with suitable outer coating and core material. For example, silicone rubber-coated metal mesh is suitable for a wide temperature range, while Monel wire mesh offers good corrosion resistance.

3. Compression Deformation and Closing Force: The gasket should be able to be compressed to its optimal design operating range (typically 25%-50% compression) under normal door closing force to provide stable conductive contact while preventing door deformation or permanent gasket failure due to excessive closing force.

4. Installation Method: Based on the structure of the cabinet door and frame, select a gasket with adhesive backing, slot mounting (U-slot), or screw fixing.
