1 Pairs Passive PoE Injector and PoE Splitter Kit with 5.5x2.1 mm DC Connector RJ45 Power Over Ethernet

​Specifications:Power Pin Pin: 4/5 (+), 7/8 (-)Data Pin Pins: 1,2,3,6DC female head: 5.5*2.1mmDC male head: 5.5*2.1mmDC Input Voltage:12VDC Output Voltage: 12VOver Current Protection NoneWork range: Below 30 meters.DC Plugs :2.1mmx5.5mmFeatures:Application: WLAN, routers, switches, internet telephony, security monitoring etcUse with IP security camera, wireless access point and other devices.Can work up to 30 metres/100ft (depending on the quality of the cable and the power draw of the device).Using this set of POE power supply cables can solve the problem of power supply for indoor and outdoor equipment that is inconvenient to pull the power supply, and it is very convenient to install and control the power supply of the equipment indoors! It can also be used for WLAN, wireless routers, switches, Internet phones, gateways, access control, security monitoring, etc.The principle of POE power supply through the cable: The standard Category 5 network cable has four pairs of twisted pairs, but only two of them are used in l0M BASE-T and 100M BASE-T. IEEE80 2.3af allows two usages. When using idle pins for power supply, pins 4 and 5 are connected as positive poles, and pins 7 and 8 are connected as negative poles. When using the data pin to supply power, add the DC power to the midpoint of the transmission transfer, which will not affect the data transmission. In this way, pairs 1, and 2, and pairs 3, and 6 can be of any polarity. The standard does not allow both cases to be appPackaging includes:1 pair POE Cable Adapter
