Industrial Gigabit Ethernet Switch 3-Port 1000M RJ45 to 1000M SFP Fiber DIN Rail

Mini Industrial 3-Port 10/100/1000T + 1-Port 100/1000X SFP Gigabit Ethernet Switch

Product Overview:

The LNK-IMC103G-SFP Series is a compact industrial-grade Gigabit Ethernet switch engineered for robust performance in demanding environments. Featuring three 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 (single or dual core), for customized long-distance connectivity.

Housed in an IP40-rated 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 both half and full-duplex transmission modes with auto-negotiation for optimal network flexibility and compatibility.

Ideal for network integration between remote locations, this switch provides reliable connectivity for IP cameras, wireless access points, and other network devices. Its compact design allows for easy installation in space-constrained applications while maintaining industrial-grade durability and performance standards, making it perfect for smart city infrastructure, power utility networks, and mobile deployment scenarios.
