Industrial 8-Port Gigabit Switch with SFP

The Intellinet Industrial 8-Port Gigabit Switch delivers eight auto-sensing 10/100/1000 Mbps RJ45 ports plus two SFP slots for fiber uplinks. Its IP40-rated metal housing and DIN-rail mounting suit factory floors, outdoor cabinets and transportation infrastructure. Redundant 12-48 V DC inputs with a power-failure alarm keep critical IoT and Industry 4.0 links alive.

Sustained operation from -40 to 75 °C

The switch maintains full Gigabit throughput across the entire -40 to 75 °C (-40 to 167 °F) range without fans or throttling. Port surge protection up to 6 kV shields connected devices from transients common in industrial power networks. Redundant DC feeds and the one-way relay alarm give immediate notice of a supply loss so operators can act before a segment goes dark.

Replaces office-grade switches in harsh sites

It upgrades any unmanaged plastic-cased switch that cannot survive vibration, dust or temperature extremes. The jump is worth it when downtime costs exceed the price delta and when fiber links over copper distance limits are required. Buyers who need managed features, PoE budgets or rack-mount form factors should look elsewhere.

Questions about this item

Does the fanless IP40 metal housing stay quiet and cool when the switch runs 24/7 at 75 °C ambient?

Yes, the rugged IP40-rated metal housing operates silently without fans and is rated for continuous use from -40 °C up to 75 °C ambient temperature.

Which power supplies and cables must I already have to connect the dual 12-48 V DC inputs and the alarm relay?

You need two DC sources between 12 V and 48 V with wires for the terminal block, plus a separate circuit for the 1 A, 24 V DC relay alarm output.

Will my legacy 10 Mbps and 100 Mbps devices work on the eight RJ45 ports alongside new 1000 Mbps gear?

Yes, every port auto-senses 10, 100 or 1000 Mbps so older and newer Ethernet devices share the switch without configuration.
