Industrial 8-Port Gigabit PoE+ Switch + 1-Port Fiber Uplink -40~80°C
Overview
The LNK-IMC108GP is a rugged 8-Port Gigabit PoE+ + 1-Port 100/1000Base-X industrial
Ethernet switch designed for reliable power and data delivery in harsh environments. Each
RJ45 port supports IEEE 802.3af/at PoE+ (30W per port, 253W total), enabling seamless
connectivity for IP cameras, wireless access points, and other powered devices. With
redundant 48~57VDC power input, robust aluminum housing, and wide -40°C to 80°C
operating temperature, this switch ensures stable operation in CCTV surveillance,
industrial automation, and remote networking applications.
