The SX barrier combines the Ex d / Ex ia antenna barrier and surge protection on the RF signal in a single fitting. It is the choice for exposed antennas, on masts or in lightning-prone areas, where the radio must be protected from induced surges.

Key features

  • Integrated surge protection to IEC 61643-21 category C2
  • 700 MHz – 3.9 GHz and 4.6 – 6 GHz band (cellular, WiFi 2.4/5 GHz)
  • Mounts directly on the Ex d enclosure, with no sealing fitting
  • Antenna removable while energised thanks to the blocking circuit
  • AISI 303 or 316L stainless steel body, resin-potted electronics
  • RF power 2 W as standard, 6 W with the -13 suffix
