Datasheets

The RX barrier lets you connect standard, non-Ex-certified antennas to radios, modems and access points installed in flameproof enclosures. An integrated blocking circuit prevents hazardous energy from reaching the antenna if the radio fails, and allows the antenna to be removed in the hazardous area without isolating the power.

Key features

Very low insertion loss: ideal for low frequencies (100 MHz – 1.4 GHz) and for the 700 MHz – 6 GHz band
RX1 version with antenna ground isolated from the enclosure, preventing ground loops with remote antennas
Screws directly into the entry of the Ex d enclosure or fitting, with no sealing fitting required
Works as a bulkhead feedthrough: takes up no space inside the enclosure
Resin-potted electronics, AISI 303 or 316L stainless steel body
RF power 2 W as standard, 6 W with the -13 suffix
