HWA and HWS junction boxes solve the routing of a coaxial cable from the safe area to an antenna in the hazardous area, or its extension in the field. The RX (low frequencies) or UX (above 1 GHz) barriers fitted on the box make the output intrinsically safe, so a standard antenna can be used.

Key features

  • 1 or 2 integrated RX or UX antenna barriers
  • Ex d enclosure in painted aluminium (HWA) or AISI 316 stainless steel (HWS), IP66/68
  • N male or N female internal connector
  • 3/4" NPT or M25x1.5 entries
  • Temperature -40 °C to +80 °C
