In scenarios such as industrial security and enterprise wireless networking, non-PoE switches cannot directly supply power to PoE terminals, and long-distance wiring also faces the dual challenges of power supply and data transmission. The E-link LNK-INJ301-30 12-48V DC input industrial gigabit PoE+ injector is specially designed for harsh industrial environments.
It can efficiently solve the problems of power supply and simultaneous data transmission, providing reliable support for the stable operation of network equipment.
LNK-INJ301-30 is an industrial ruggedized gigabit PoE+ injector with wide voltage input. It is compatible with the IEEE 802.3af/atPoE power supply standard and can integrate power and Ethernet data signals for output. This PoE Injector enables non-PoE switches to directly drive PoE cameras, wireless APs, IP phones, and other terminal devices. It is a core supporting device for industrial network power supply.
This PoE Injector is connected to a 12-48VDC wide-voltage power source through the terminal block, and simultaneously acquires the Ethernet signal of the switch from the RJ45 data input port. Internally, it adopts a full-foot power supply design, integrating the power and the gigabit data signal without interference, and then synchronously transmits them to the terminal device through the PoE output port. The maximum transmission distance can reach 100 meters.
The power supply pins are defined as pins 1 and 2 as the positive pole, pins 3 and 6 as the negative pole, pins 4 and 5 as the positive pole, and pins 7 and 8 as the negative pole. The full-foot synchronously outputs power, and throughout the process, it does not affect the 10/100/1000Base-TX gigabit data transmission. It can automatically identify the power-consuming devices that comply with the IEEE802.3af/at standard, ensuring stable and efficient power supply and data transmission.
This industrial PoE Injector boasts extremely strong environmental adaptability and industrial-level protection capabilities. It can operate within a wide temperature range of -40°C to 80°C, suitable for harsh environments with both high and low temperatures. The aluminum alloy metal casing enhances anti-interference and durability. It supports gigabit network transmission, with a maximum output power of 30W per port, meeting the power supply requirements for high-power PoE devices.
This PoE Injector is compatible with a wide voltage range of 12-48VDC, adapting to various power supply solutions in industrial settings. Additionally, it features 1KV surge protection for the network port, 500V surge protection for the power supply, and 4KV/8KVESD protection. The MTBF exceeds 200,000 hours. Equipped with LED diagnostic indicators, it enables quick fault detection. The DIN rail and wall-mounted dual installation methods also make deployment more flexible, significantly reducing the cost and maintenance difficulty of industrial network cabling.
This PoE Injector is widely applicable in scenarios such as industrial security monitoring, enterprise wireless coverage, and communication terminal deployment. It can support the stable operation of terminals including IP cameras, CCTV security transmission equipment, wireless APs, and IP phones. Whether in factory workshops, outdoor monitoring points, or office networking scenarios, it can achieve power supply and synchronous data transmission, ensuring the continuous and reliable operation of the equipment.
The LNK-INJ301-30 industrial PoE injector, with its core advantages of wide voltage input, industrial reinforcement, gigabit transmission, and high power output, has become the preferred solution for industrial network power supply. It can effectively simplify wiring, enhance equipment stability, and provide safe and efficient power supply and data transmission guarantees for various PoE terminal devices.
