Industrial 4-Port UPoE 60W Switch 2 SFP Ports DIN Rail 240W 802.3at
Model: LNK-GYH204GP-SFP
Product Description & Overview
The Unmanaged Industrial 4-port 10/100/1000T UPoE (60W high Power) + 2-port 1000X SFP Ethernet
Switch delivers a robust networking solution designed for demanding industrial and outdoor environments.
This compact yet powerful switch integrates four Gigabit Ethernet ports with Universal Power over Ethernet
(UPoE) capability, each capable of delivering up to 60W of power, alongside one standard Gigabit copper
port and two 1000X SFP fiber optic uplink ports. With a total PoE budget not exceeding 250W, this device
efficiently powers high-power PoE/PoE+ devices such as PTZ cameras, wireless access points, industrial
sensors, and VoIP systems while providing reliable network connectivity through both copper and fiber
interfaces.
Engineered for industrial-grade reliability, this unmanaged switch features automatic detection and intelligent
power management that recognizes IEEE 802.3af/at compliant devices and supplies appropriate power
levels through standard network cables. The fanless design ensures silent operation with low power
consumption, while the rugged metal construction provides exceptional durability against vibration, dust,
and extreme temperature fluctuations. This combination makes the switch ideal for deployment in challenging
environments where traditional commercial networking equipment would fail to perform reliably.
This versatile switch serves multiple industrial applications including intelligent transportation systems,
railway signaling networks, power generation and distribution facilities, mining operations, and renewable
energy installations. By consolidating high-power PoE delivery with fiber optic connectivity, it significantly
reduces infrastructure complexity and installation costs in applications requiring both power and data
transmission to remote devices. The integration of SFP fiber ports enables long-distance network extension
while maintaining high bandwidth capacity, making this switch an optimal solution for creating cost-effective,
stable communication networks in industrial settings where reliability and performance are critical requirements
for operational success.
