The flow chart in Table 1 will assist the designer in selecting the appropriate shielding options necessary to meet their shielding and environmental requirements. The shielding requirement flow chart begins by identifying the type of NEMA or IP enclosure based on the intended environment (indoor/outdoor, military/commercial, marine or land/desert).
Then, using the resulting letter designation A-F and continuing on to the second shielding flow chart (Table 2), the engineer can then evaluate the available shielding product options for the particular NEMA/IP enclosure.
In addition, all shielding products shown in the table, depending on profile, configuration, compression, galvanic compatibility, required attenuation, etc., will enable an electronic product to meet MIL-STD-461 and other military or commercial specifications.
