Mini Industrial 4-Port 10/100/1000T + 1-Port 100/1000X SFP
Gigabit Ethernet Switch
Product Overview:
The LNK-IMC104G-SFP Series is a compact industrial-grade Gigabit
Ethernet switch engineered for robust performance in demanding
environments. Featuring four auto-negotiation 10/100/1000BASE-T
copper ports and one versatile 100/1000BASE-X SFP fiber slot, it
enables seamless media conversion and network integration. The SFP
interface supports flexible deployment with various pluggable
modules, including both single-mode and multi-mode fiber types, for
customized long-distance connectivity.
Housed in a rugged metal enclosure, this hardened switch operates
reliably across an extended temperature range of -40°C to 75°C,
ensuring stable performance in harsh conditions including
industrial automation, outdoor surveillance, and transportation
systems. It supports wide-range 12~48VDC power input, making it
suitable for solar-powered applications, renewable energy systems,
and mobile deployments with fluctuating power sources.
This unmanaged switch offers plug-and-play operation while meeting
CE, FCC, and industrial standards. It undergoes rigorous 100%
burn-in testing to guarantee reliability in critical applications.
The compact design allows for easy installation in
space-constrained applications while maintaining industrial-grade
durability, making it perfect for smart city infrastructure, power
utility networks, and remote monitoring systems.
