PoE Splitter.
PoE in, plain power out.
The mirror image of an injector. Take a Power-over-Ethernet line and split it back into a normal Ethernet data lead and a separate DC power plug — so a device that doesn’t speak PoE can still run straight off your PoE network. Selectable 5 V / 12 V output.
01
Why it’s handy.
Power
Power non-PoE gear from PoE
Have a device with a plain DC barrel — a mini PC, a non-PoE coordinator, a small sensor hub — but only a PoE network where it needs to live? The splitter bridges the gap.
Voltage
Pick the voltage
A selectable 5 V / 12 V DC output matches the device you’re powering, so there’s no separate adapter to find or lose.
Tidy
One cable to the corner
Run a single PoE cable to the point of use and split it there into data and power — no power socket required at the far end.
Standard
Standards-based
IEEE 802.3af/at compliant, so it draws power cleanly from any standard PoE switch or injector.

The specifics.
PoE splitter
| Standard | IEEE 802.3af / 802.3at |
| Function | PoE in → data out + DC power out |
| DC output | Selectable 5 V / 12 V |
| Data | Gigabit pass-through |
| Connector | DC barrel on the power output |

Quick questions.
Q-01
How is this different from an injector?
Opposite jobs. A splitter takes power off a PoE cable so a non-PoE device can run from it. An injector puts power onto a cable so a PoE device can run from an ordinary network.
Q-02
Which voltage should I choose?
Match your device — 5 V for most single-board computers and small hubs, 12 V for devices that ask for it. The output is selectable.
