StarTech Series 1G Ethernet Coupler, 2 Ports, 3.3cm Length - 1G-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.

Features and Benefits:

• 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

Applications

• 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

How does the device connect to existing cabling?

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

What port count and layout should I expect for integration?

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

Is the product intended for high-security ethernet installations?

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

What physical footprint considerations are relevant for panel planners?

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