PoE Extenders, Injectors & Splitters

Power over Ethernet (PoE) simplifies installations by delivering both power and data through a single cable, but not every device or setup is PoE-ready out of the box. That’s where PoE accessories come in. Industrial PoE injectors add power to Ethernet lines for devices that need it, splitters separate power and data at the endpoint for non-PoE equipment, and PoE extenders help you push past the 100-metre Ethernet limit without extra cabling or power sources.

These devices are built for harsh environments, with rugged casings, DIN-rail mounting, and wide temperature tolerances to suit factory floors, outdoor enclosures, transport systems, and more.

Frequently Asked Questions

Learn More About POE Extenders, Injectors & Splitters

A PoE extender is used to extend the reach of a PoE connection beyond the standard cable distance. A PoE injector adds power to an Ethernet connection so that power and data can be delivered together over one cable. A PoE splitter does the reverse, separating the power and data at the device end so that equipment without native PoE support can still be connected.

A PoE injector is typically used when the network switch or router does not provide PoE, but the connected device still needs power over Ethernet. It can be a practical way to add PoE capability without replacing the main switching hardware.

A PoE extender is useful when a powered device needs to be installed further away than a standard Ethernet cable run would normally allow. This can be helpful in applications such as surveillance, transport infrastructure, industrial monitoring, or outdoor networking where the device location is dictated by the site rather than the cabling limit.

Key considerations include whether you need to extend, add, or separate PoE, along with the required power level, Ethernet speed, cable distance, mounting method, and installation environment. The right choice depends on both the device being connected and the practical layout of the network.
