Industrial 4-port 10/100/1000T 802.3bt PoE + 4-port 10/100/1000T 802.3at PoE + 2-port 100/1000X SFP Managed Ethernet Switch
LNK-GYM7208GHP-SFP Industrial Managed Ethernet Switch Overview
The LNK-GYM7208GHP-SFP Series is a next-generation industrial managed PoE switch featuring
4 x 802.3bt (90W) PoE++ ports, 4 x 802.3at (30W) PoE+ ports and 2 x Gigabit SFP fibre slots
for high-speed, long-distance connectivity. This product has been designed to withstand the rigours
of industrial environments, ensuring consistent and dependable Ethernet transmission.
It features dual power inputs (12-48V DC) for redundancy, operates fanless, and boasts
a wide temperature range (-40°C to 80°C). Its compact, rugged IP40 metal housing supports DIN-rail
or wall mounting, making it ideal for industrial automation, ITS (Intelligent Transportation Systems),
military and utility networks. This switch is equipped with advanced Quality of Service (QoS), VLAN,
and network management features, ensuring high-bandwidth, low-latency, and secure data transmission
for mission-critical applications.
