Compact Gigabit Network Isolator

The StarTech 1G-NETWORK-ISOLATOR provides galvanic isolation up to 4kV for a single Ethernet link. It separates all conductive connections between two devices using standard RJ45 ports. The unit helps prevent ground loops and blocks stray electrical currents on Cat5 or Cat6 cables. It includes a DIN rail kit and adhesive strip for flexible mounting options.

Check your cabling and mounting needs

Verify that both connected devices use standard RJ45 Ethernet ports compatible with Cat5 or Cat6 cabling. Ensure you have a suitable DIN rail or flat surface for the included mounting hardware. Confirm that 1Gbps throughput meets the bandwidth requirements for your specific network segment. This isolator adds physical bulk between connections, so check available space at the installation point.

Questions about this item

Does the isolator ship with mounting hardware or do I need to buy it separately?

The package includes a DIN rail kit and an adhesive strip so you can mount the unit without extra parts.

Should I choose the 40 or 45 version for my network?

Only one model is offered — 1G-NETWORK-ISOLATOR — so there are no capacity or version options to select.
