StarTech.com 1G Series 2 Port RJ45 Network Isolator

This ethernet coupler provides passive galvanic separation for RJ45 links in industrial and commercial networks. It serves as an inline network isolator to help prevent common-mode currents and reduce the risk of electrical disturbances between connected devices while maintaining Gigabit Ethernet connectivity for automation, electronics, electrical and mechanical systems.

• Supports 1G data rate while reducing ground-loop currents
• Two RJ45 ports enable inline network isolation between devices
• TAA-compliant supply chain suitability for regulated procurement
• Compact 3.3cm length for constrained installation spaces
• Narrow 6.7cm width for dense panel or rack mounting

• Suitable for isolating industrial control system segments
• Ideal for protecting measurement equipment from transient currents
• Used with factory automation ethernet switches for separation
• Can be used for segregating test benches and development rigs

It uses standard RJ45 interfaces on both ends to mate directly with Cat5e/Cat6 terminated cables for straightforward inline insertion.

The unit provides two network ports configured to join two RJ45 links while presenting an isolating barrier between them.

It offers physical isolation at the link layer to support ethernet security practices by minimising electrical coupling between segments.

The Compact form factor is designed for installations where minimal length and modest width reduce space impact in confined enclosures.
