    Single port voltage extractor with 2.1mm x 5.5 mm DC connector for 5 to 56 volts

The WS-POE-IO PoE Injector Splitter set allows you to power one device remotely. Passive Power-over-Ethernet (PoE) allows low cost of delivery of power over the network cable. This scheme allows power to be carried on 10/100 networks over the spare, unused pairs of a CAT5, CAT5E, or CAT6 Ethernet network cable.

Depending on distance (see ) the power source could be the power supply that came with the wireless access point, IP video surveillance camera, etc. This set contains a very cost effective injector and breakout or splitter component. The injector inserts the DC voltage at the source location into the 3.5mm x 1.35mm injector plug. The DC voltage is then carried over the spare pairs of the 10BASE-T or 100BASE-T network cable. The breakout or splitter extracts the DC voltage from the network cable onto the 3.5mm x 1.35mm splitter jack. Also available is a 2.1mm version WS-POE-IO

Note: if you use this with a 5 volt device – keep in mind that with a 5 watt device, the ethernet cable will lose up to .4 volts every 10 feet – so the distance is limited. We have a calculator on our web page to figure this for you.

Please see our 5 volt active splitters for flawless operation up to 328 feet at

Another method is to use a 6v power supply – this will extend the useful range to about 35 feet – but will cause the voltage at the camera to vary far outside of the stated specs.

Product Description:

  • RJ-45 connectors, one female with power, one male without power.
  • Note – typical 12 volt devices will operate to about 100 ft
  • Note – typical 5 volt devices will operate to about 15 ft
  • 2.1mm x 5.5mm DC power plug
  • see also our active 12v and 5v splitters.

Note: the distance you can power a device depends on the voltage and current. You can use this online calculator to see if your device will work. Calculate POE
