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.
