Industrial 20-Port Ethernet Switch with 16 Fast RJ45 + 4 Gigabit SFP Ports

Overview

The LNK-GY416-SFP is a rugged industrial-grade Ethernet switch designed for reliable data

transmission across harsh environments. Featuring 16×10/100Base-TX ports and 4×1000Base-SFP

uplinks, it delivers a seamless mix of copper and fiber connectivity for flexible industrial networking.

Built with an IP40-rated aluminum enclosure, the switch ensures durability, high EMI/EMS protection,

and fanless heat dissipation. Dual redundant 24VDC power inputs safeguard continuous operation,

while its wide -40°C to +80°C temperature range makes it ideal for factory automation, power utilities,

and transportation systems requiring stable and high-speed communication.
