Network Managed Industrial 4-port 10/100/1000BASE-T + 2-port 100/1000BASE-X SFP Ethernet Switch

Model: LNK-GYM7204G-SFP Series

Network Managed Industrial Gigabit Ethernet Switch , Power Over Ethernet Switch 0


LNK-GYM7204G-SFP Serie is a new generation industrial Managed switch with 4-Port 10/100/1000Base-TX and 2-Port 100/1000Base-X SFP that provide stable and reliable Ethernet transmission offered by E-link, with high quality design and reliability. It is positioning in the broadband network intervention market, to offer and realize Ethernet data exchange, convergence and long-distance optical transmission with efficient bandwidth and reliable fiber optic network solutions for users. The industrial switch complies with various characteristics such as mini size, no fan, low power consumption, high reliability and stability, and easy to maintain.
With dual power input design, LNK-GYM7204G-SFP can offer redundant mechanisms for critical applications that need always-on connections. It can also operate either at standard operating temperature range -40 to 80°C. Housed in rugged DIN rail or wall mountable IP40 enclosures, these switches are perfect choices for harsh environments, such as industrial networking, intelligent transportation systems (ITS) and are also suitable for many military and utility market applications where environmental conditions exceed commercial product specifications.
