UL-listed Type LAS is flexible steel conduit with galvanized steel core, over which a tinned copper shielding braid is applied. The outer jacket is flexible PVC with a temperature rating of -20 to 60° C with a shielding effectiveness from 126 dB @ 1 MHz to 66 dB @ 1 GHz. Type EMS offers shielding effectiveness from 126 dB @ 1 MHz to nearly 100 dB @ 1 GHz with temperature rating of -55 to 105° C. Type EMSP is hybrid of LAS and EMS, but gets further screening protection from a tinned copper shielding braid under the flexible jacket.
