The Industrial 8-Port Gigabit Ethernet Switch with 2 SFP Ports from Intellinet Network Solutions was designed to give you the network connections you need in places that are less than calm or temperate. With its rugged, IP40-rated metal housing, it operates reliably and quietly, even under extreme temperatures that range from -40 to 75℃ (-40 to 167°F). In combination with its DIN-rail mounting option and two safe redundant DC power inputs with power failure alarm and plenty of other safety features, this switch is ideal for IoT applications in Industry 4.0 and more. Featuring eight auto-sensing 10/100/1000 Mbps RJ45 Gigabit Ethernet ports, this unmanaged switch offers plenty of performance for the devices in your network. In addition, two small form-factor pluggable GBIC module slots (SFP) provide fiber connectivity for greater distances.
