Industrial 4-Port 10/100T + 2-Port 100FX Ethernet Switch Redundant Power
Overview
The LNK-IMC204 is a hardened 4-Port 10/100Base-T + 2-Port 100Base-FX industrial
Ethernet switch, providing reliable data transmission in harsh environments. Each RJ45 port
supports Full/Half duplex, Auto MDI/MDIX, while the fiber ports support single-mode or
multi-mode SFP, SC, FC, or ST modules. With redundant DC power inputs, DIN-Rail and
wall-mount options, and a wide -40°C to 80°C operating range, this switch is ideal for IP
cameras, wireless access points, and industrial automation networks across remote
locations.
