Industrial 8-Port Gigabit Switch with 4 RJ45 + 4 SFP DIN-Rail IP40
Overview
The LNK-GY404G-SFP is a high-performance industrial Gigabit Ethernet switch featuring 4 RJ45
copper ports and 4 SFP fiber slots, providing maximum flexibility for mixed media networking.
Designed for harsh industrial environments, it operates reliably in a -40°C to +80°C temperature
range with IP40-rated aluminum housing.
With its redundant ring protocol, this switch ensures network recovery within 20ms, maintaining
continuous communication in critical applications such as intelligent transportation, power automation,
and security monitoring. It supports IEEE 802.3 standards, auto MDI/MDI-X, and plug-and-play
setup—ideal for stable, maintenance-free operation in field deployments.
