The passive Power-over-Ethernet (PoE) injector + splitter kit or set 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. Product Details: Injector: RJ45 Male + Power In to RJ45 Female Splitter: RJ45 Female to RJ45 Male + Power Out Passive PoE - means that input and output voltage are equal. Works with all DC powered non-PoE devices Supports 12V,15V Power supply required for power input - simply use the power supply (wall transformer) that is provided with the device you are trying to power. Uses industry standard 5.5mm x 2.1mm power plugs Can work up to 150ft (depending on the quality of the cable and the power draw of the device) 5 pairs x POE Separator Power Over Ethernet splitter Power Receiver injector Cable we are glad to combine them shipping to you if you want to order others. 4.40%7.00%10.70% We are glad to send items worldwide. please email us firstly, Try to do free shipping or less shipping fee to buyers.
