Electri-Flex's EMI/RFI shielding conduit is available in three types for various applications. Type EMS offers a high degree of shielding effectiveness and a temperature rating of -55 ° C to 105 ° C. It features a flexible core constructed of a helically wound interlocked strip of bronze. An all-temperature PVC jacket is then extruded over the core, resulting in a sealed, waterproof raceway when assembled with liquidtight fittings. Type EMSP is identical to EMS, except for the addition of a tinned copper shielding braid under the flexible jacket, to further enhance the shielding characteristics. Type LAS provides a UL Listed version. Conforming to UL 360, Type LAS is a flexible steel conduit with a galvanized steel core, over which a tinned copper shielding braid is applied. The outer jacket is flexible PVC with a temperature rating of -20 ° C to 60 ° C.
