Purpose & audience

The PoE Texas GAF-12v12w is a Gigabit PoE splitter that converts IEEE 802.3af power into 12 volts at 12 watts for non-PoE devices. It suits installers who need to run IP cameras, Arduino boards, or media players up to 328 feet from a PoE switch or 48 volt injector without adding local mains wiring.

Upgrade path

It replaces a separate wall adapter and short Ethernet run when a PoE switch or injector already exists on the network. The jump is worth it when the target device draws no more than 12 watts at 12 volts and the cable distance stays within the 328 foot Ethernet limit.

Compatibility checklist

Verify the source equipment supports IEEE 802.3af at 44 to 56 volts and that the powered device uses a 5.5 millimetre by 2.1 millimetre barrel connector with centre-positive polarity. Confirm the total cable run does not exceed 328 feet and that the switch or injector can deliver the required 12 watts per port.

Questions about this item

What size barrel plug does the GAF-12v12w use for 12 V output?

The splitter provides a 5.5 mm × 2.1 mm barrel connector that fits most 12 V devices.

How do I connect the splitter inline between the PoE switch and my camera?

Plug the PoE switch cable into the splitter RJ45 input, then run a second Ethernet cable from the splitter RJ45 output to the camera while the barrel plug powers the camera.

How far can I run the Ethernet cable from the PoE source to the splitter?

The unit supports up to 328 feet of cable between the 802.3af PoE switch or injector and the splitter.
