![Extralink 4 Port | Gigabit PoE Injector | 4x 1000Mb/s RJ45 Ilość portów LAN4x [10/100/1000M (RJ45)]](https://www.batna24.com/img/200/291141_1.jpg)
4-port PoE injector Extralink supports 10/100/1000 M Ethernet throughput. RJ45 LAN connectors are designed to connect the switch/PC/HUB and pins 1/2 & 3/6 & 4/5 & 7/8 transmit data. The POE RJ45 connectors provide both data and PoE power, the pins 1/2 & 3/6 & 4/5 & 7/8 are for data and the pins 4/5 (+) & 7/8 (-) for power. The unit consists of 4 sets of RJ45 sockets and one power outlet up to 60 V DC. The power input has a diameter of 5.5 mm. The total output power must be less than the maximum input power of the AC-DC supply, otherwise a stronger AC-DC supply must be considered. The recommended power formula for the AC-DC adapter is 10 W per RJ45 kit (1 kit = 2 x RJ45 sockets). For example, 4 x 10 W = 40 W for a PoE panel with 4 ports.

The PoE gigabit injector is used to transfer power to active devices via a UTP/FTP cable.
Power over Ethernet, or PoE for short, is a technology based on several standards for the transmission of electricity via twisted-pair cable to Ethernet peripheral devices.
Many types of PoE injectors are available on the market. The choice depends on how many devices we want to connect, whether it is possible to mount them in a rack etc.
