Product Overview:
The LNK-IMC103GP-SFP Series is a compact industrial-grade Gigabit Ethernet switch engineered for robust performance in demanding environments. Featuring three 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.
