12~48VDC Power Input Industrial 2-Port Gigabit PoE+ Injector
Industrial Gigabit PoE+ Injector Overview
The LNK-INJ302 Hardened Gigabit High-Power PoE Injector delivers robust power and data integration for outdoor and
industrial network deployments. This compact 2-port solution
enables seamless connectivity between standard non-PoE network switches and IEEE 802.3af/at compliant devices, including high-power access points and pan-tilt-zoom
cameras, across distances up to 100 meters. Featuring Gigabit throughput on both data input and powered
output interfaces, the injector maintains full compliance with IEEE
802.3ab standards for reliable high-speed data transmission while
supporting PoE+ power budgets for demanding connected equipment.
Engineered for challenging environments, the device accepts a wide 12-48V DC input range, ensuring stable operation despite voltage fluctuations in
industrial power systems. Its hardened construction provides
superior resistance to moisture, dust, and temperature variations,
making it suitable for deployment in uncontrolled outdoor
locations, manufacturing facilities, and transportation
infrastructure. The plug-and-play design requires zero
configuration, allowing immediate integration into existing network
architectures while eliminating the need for separate power
cabling. This cost-effective power sourcing solution is
particularly valuable for expanding wireless coverage, surveillance
system capabilities, and IoT device networks without requiring
infrastructure upgrades.
