12-Port Industrial Gigabit Managed Ethernet Switch, w/8*10/100/1000Tx + 4*100/1000 SFP. EOT: -40° ~ 75°C

Antaira’s LMX-1204G-SFP-T is a 12-port industrial gigabit managed Ethernet switch that is embedded with 8*10/100/1000Tx Fast Ethernet ports and four dual rate (100/1000X) SFP slots. This model is a fully manageable industrial Ethernet switch pre-loaded with standard Layer 2 network management software. It supports Jumbo Frame and wide bandwidth for data transmission and has sufficient port counts for any edge level connectivity solutions.

The LMX-1204G-SFP-T has a compact form factor design with an IP30 rating, DIN-rail mounting, and standard operating temperature support from -40°C to 75°C. It also provides high EFT and ESD protection for any industrial networking application within factory automation, ITS, power/utility, water wastewater, or any other outdoor or harsh environment.
