E-Link EN50155 Compliant M12 PoE Injector
Overview
The E-Link EN50155 compliant PoE Injector is engineered for demanding industrial
applications, including rolling stock, vehicles, and railway systems. This advanced
IEEE802.3at PoE device features Intelligent Detection, offering a single 10/100/1000
Base-T(X) PoE output port that meets EN50155 standards. Designed to withstand harsh
environments, the PoE injector utilizes M12 connectors for secure, durable connections,
ensuring reliable operation even in conditions with vibration and shock. It only powers on
when a valid PoE signature is detected from downstream devices, protecting non-PoE
devices from potential damage. The LNK-INJ301-M12 provides an integrated power solution
with a wide voltage input range of 12-48VDC, ideal for high-availability applications.
