12~48VDC Power Input Industrial 2-Port Gigabit PoE+ Injector
Model:LNK-INJ302
Overview
The LNK-INJ302 is a rugged 12~48VDC Power Input Industrial 2-Port Gigabit PoE+ Injector,
engineered to bridge non-PoE LAN switches with IEEE 802.3af/at PoE devices—such as
industrial cameras, wireless access points, and sensors—over distances up to 100 meters.
As a dedicated 12~48VDC Power Input Industrial 2-Port Gigabit PoE+ Injector, it excels in
industrial environments requiring reliable power and data transmission.
Both its Ethernet port (for connecting to switches) and PoE Out port (for PoE devices) support
10/100/1000Base-T standards, complying with IEEE 802.3ab for gigabit data rates, while the
PoE Out port further adheres to IEEE 802.3at (PoE+) to deliver sufficient power for high-demand
devices. This 12~48VDC Power Input Industrial 2-Port Gigabit PoE+ Injector is built with industrial-
grade durability, resisting vibration, shock, and wide temperature fluctuations—key for stable
operation in factories, outdoor surveillance, and industrial automation setups.
With its integrated 12~48VDC wide-range power input, the LNK-INJ302 adapts to diverse
industrial power systems, ensuring high availability in scenarios where power supply stability
is critical. It serves as a robust solution for extending PoE functionality in industrial networks,
balancing performance, compatibility, and ruggedness.
