Industrial 5-Port Gigabit Switch

The StarTech I51G-ETHERNET-SWITCH is an unmanaged 5-port gigabit switch built for industrial environments. It connects Ethernet devices over standard RJ45 ports at 1 Gbps. The unit operates across a -40 °C to 75 °C temperature range and carries an IP30 rating. It suits automation cabinets, transport infrastructure and outdoor enclosures where commercial switches would fail.

Fanless Operation And 60 V Input

The switch runs without fans, so it adds no acoustic noise to a control cabinet. Power is supplied through a 3-pin terminal block at 60 volts DC, matching common industrial bus voltages. The sealed metal housing dissipates heat passively across the full -40 °C to 75 °C span. No moving parts means reduced maintenance in vibration-prone locations.

DIN Rail Kit And Terminal Block Included

A DIN rail mounting kit and a 3-pin terminal block ship in the box, so the switch can be clipped onto standard rails and wired directly to a DC bus without extra parts. A mounting ear kit and a quick-start guide are also provided. Installers needing SFP uplinks, PoE ports or managed features must select a different model.

Questions about this item

How do I mount the switch on a DIN rail using the included kit?

Attach the supplied DIN rail mounting kit to the switch chassis, then clip the assembly onto a standard DIN rail until it locks; the step often missed is fully seating the latch so the unit cannot slide.

What maintenance will the 3-pin terminal block need over time?

Periodically inspect the terminal block screws for tightness and check for corrosion on the power contacts; re-torque if vibration has loosened them.

Which limit appears first during continuous operation at high temperature?

The operating ceiling of 75 degrees Celsius is the first hard limit; sustained loads beyond that risk thermal shutdown.
