Description

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.
