BXF and BAF barriers bring a 100BASE-TX Ethernet network into the hazardous area with a standard CAT5e cable, with no sealing fittings or special cables. A barrier is needed at each end of the cable: BXF on devices in the hazardous area, BAF on the safe-area side or in pressurised panels.

Key features

  • BXF: Ex d + Ex ia, screws into the cable entry of the flameproof enclosure
  • BAF: Ex ia associated apparatus for the safe area or Ex p panels
  • D-coded M12 female external connector, hot-pluggable and unpluggable
  • Internal side RJ45 male or M12 male/female with CAT5e cable
  • AISI 303/316L stainless steel body (BAF also aluminium)
