MTL 9460-ET intrinsically safe ethernet products

The Crouse-Hinds series MTL 9460-ET product range provides cost-effective Intrinsically Safe (IS) Ethernet equipment that can be installed and maintained easily in hazardous areas. The intrinsically safe hazardous area certification permits the components to be mounted in a Zone 1, or Division 1 hazardous area with connectivity into Zone 0.  

In Process Automation it is also preferable to use a single cable to provide both power and communications to the end device. The 9460-ET range can deliver Intrinsically Safe Power over Ethernet (PoEx™) with a single Cat 5e or Cat 6 cable, allowing live connection and disconnection of the end device in Zone 0 and 1 hazardous areas.

The MTL 9460-ET range includes:

  • Ethernet Gateway (9461-ET)
  • Copper to Fibre Optic Media Converter (9465-ET)
  • Ethernet Switch (9466-ET)
  • Ethernet Isolator (9468-ET)
