Product Specification

Mini Industrial 4-Port 10/100/1000T 802.3at PoE + 1-Port 100/1000X SFP Ethernet Switch with 12~48VDC Input and Voltage Booster

Product Overview:

The LNK-IMC104GP-SFP Series is a compact industrial-grade Gigabit Ethernet switch engineered for high-performance networking in demanding environments. Featuring four 10/100/1000BASE-T ports with IEEE 802.3at PoE+ support, it delivers up to 30W per port to power devices such as IP cameras, wireless access points, and industrial sensors. The integrated 100/1000Base-X SFP slot supports flexible fiber connectivity using single-mode or multi-mode transceivers for long-distance, noise-immune network expansion.

Equipped with wide-range 12~48VDC input and advanced voltage booster technology, this switch ensures stable operation in solar-powered systems, renewable energy applications, and mobile deployments with fluctuating power sources. Its hardened design features an IP40-rated metal housing that withstands extreme temperatures (-40°C to 75°C), vibration, and shock, making it suitable for harsh outdoor and industrial environments.

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 including intelligent transportation systems, smart grid networks, and remote monitoring installations. The compact form factor supports both DIN-rail and wall-mount installation, providing a cost-effective solution for industrial Ethernet connectivity in space-constrained applications.
