AIR802 POEPASS-01 Passive PoE Injector/Splitter with 5.5 mm x 2.1 mm DC Size Connector

AIR802® has developed a passive Power-over-Ethernet (PoE) kit or set that allows low cost of delivering power over the network cable for shorter distances. 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. On shorter network lengths, the source power 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 5.5mm x 2.1mm 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 5.5mm x 2.1mm splitter jack. Two other models are available which have different DC size connectors: model POEPASS-02 (5.5 x 2.5 mm) and model POEPASS-03 (3.5 x 1.35 mm).

*Note our return policy requires any returns to be in the original packaging. Always check the DC connector size prior to ordering.

5Easy to install - Work Great - Check the size before orderingJun 27, 2011
By RuNuts
These PoE injectors are easy and quick to put into place. It does not get any simpler than opening the package, plug one end into the power adapter and the other into the device you are using. I used this one for a D-Link D920 security camera.

For those that don't realize this, the PoE uses the unused pairs of cables in a cat 5 cable and allows power to be transmitted through those lines. It is nice if you need to put a network switch somewhere where power is not easily available.

These injectors allow for any voltage wall wort/device. I don't know the voltage drop off over longer runs, but there will be. You will need to be aware of that limitation. These are a great buy if you are running shorter distances (probably up to 50' or so). I bought the D-Link PoE injector for more money. The D-Link uses a 48 volt transformer and the voltage setting is on the adapter itself. It is limited to 5 or 12 volts to the device (common voltages for most computer routers and switches). The D-Link, with a 48 volt source, will probably be a better device to use if you are running these to the Cat5 length limit of 100 meters.

If you have a 1 gig network, you should be using a cat 5e or cat 6 wire and the two normally unused wires are being used to achieve the 1 gig network speed. If you use the injector, you will drop to a 100 meg network speed on that cable. For most users - who cares. No difference will be seen.

There are two common plug sizes that I am aware of. Make sure you have the right size plugs before ordering. If you are unsure which size to get, take your device over to Radio Shack. They have plugs that can be used to get the exact size plug. Most computer devices around are this size.

As an example, the smaller ones (3.5 x 1.35 mm) are very small and fit the Foscam FI8908W security camera.

Good little device. It appears to be well made and super easy to install.

5Great Product and Very UsefulJan 25, 2013
By Techno Geek Guru "Dave"
I've owned many network cameras over the past 10 years and still have eight functioning around my home and parent’s home. Although I'm a communications engineer these power over Ethernet adaptors could be set up by anyone! As always I run Ethernet to network cameras as it’s much more reliable than wireless. Secondly, if you need to power the unit you can kill two tasks at once by running power over Ethenet instead of installing a power outlet near every camera or running an extension cable. I recently purchased a new type of camera which was sold by Fosscam (Agasio Dome Camera). Once the camera was mounted the remaining task of powering the unit and hooking it to my router was made so much easier with these adaptors. I ran an Ethernet cable from my router to the camera (over 100ft), plugged one end into the camera with both power and Ethernet and then the cat 6 cable and then the other end into my router and power. My camera instantly came up without a problem. The camera has worked with these adaptors without a problem down to as low as -20F. The plugs on all ends fit perfectly. As they sell different size adaptors I would suggest looking at your camera specs, searching the internet and/or measuring your power plug prior to purchasing these adaptors. These units are very small and compact and were very easy to pop through a hole I had to drill. Some other units are larger square box units that would be more difficult to deal with. If I was to install any more cameras I would purchase a set of these every time. Great product.

5Awesome!Apr 26, 2011
By The Dumka
Purchased a handful of these to use on some non-PoE IP cameras. WOW! These little puppies work awesome and couldn't get any easier to integrate into the network. It was nice to centralize the camera's power supplies and it makes the cameras installation even easier since you don't need to be next to a power source. Totally recommend these.

5Works perfectly, best price I found online.Oct 26, 2010
By Pip Hobo
This is a good, inexpensive solution if your AC power outlet, Ethernet outlet and VOIPhone (or other devices that require both an Ethernet connection and DC power source) are located in different areas of your home or office. It'd be nice if these came in black as well, but white is just fine. We're ordering six more for our office.

5Just what I was looking forNov 14, 2011
These cables did just what I wanted. I have an ethernet patch panel in my apartment with no access to power. I have no idea why it was installed that way, but it meant I couldn't place a router at the panel. Even though every room has an ethernet jack, the incoming building internet signal could be sent to one and only one location in the apartment. I found the proper PoE injector size to match that power jack on my router (there are three sizes available on Amazon, I believe), and I was able to send power from another room to the patch panel. It worked to power the router so I could send a live network signal to every room in the house. I could even connect the ethernet jacks on the injector cables to send a network signal back to the same location the power came from. A perfect solution!
