MUI-A1 Series
1*10/100TX to 1*100FX extended temperature Industrial Media Converter

-40~75°CDumbMedia ConverterUL1604



MUI-A1 series, Fast Ethernet media converters are designed to operate in harsh environments. The MUI-A1 series functions at temperatures ranging from -40°C to 75°C (-40°F to 167°F), Whether on the factory floor or the street corner, the MUI-A1 series will provide flawless communications when you most need it most. MUI-A1 series are available in all types of fiber cabling and connector types. The RJ-45 port on this unit provides Auto-MDIX and auto-negotiation. The link-fault-pass-through feature allows the network management agent on adjacent equipment to react to a broken link. Flexibility is the main feature of the MUI-A1 series, it may be DIN rail or panel mounted, and comes with power options to match the applications that require a tough, environmentally hardened, Fast Ethernet media converter.
