Antaira LNX-1202G-SFP 12-Port Gigabit Unmanaged Industrial Ethernet Switches with 2x SFP and Extended Temperature Options

When a cabinet grows past eight devices, adding a second switch adds wiring, another power feed and another point of failure. The Antaira LNX-1202G-SFP series answers with more ports in one unit: industrial gigabit unmanaged Ethernet switches with 10 copper ports and two SFP slots, which Antaira positions for harsh environments and industrial applications. There is no management interface and nothing to configure, so the switch forwards traffic as soon as it is powered, and every copper port runs at full gigabit speed.

Every LNX-1202G-SFP shares the same design. The 10 RJ45 ports at 10/100/1000Base-T support auto negotiation and auto MDI/MDI-X, and the two dual-rate SFP slots take 100 or 1000 Mbps transceivers, so fiber mode and reach follow the modules chosen. Switching is unmanaged and store-and-forward on a 24 Gbps fabric with an 8K MAC table, a 4 Mbit buffer, 9.6 KB jumbo frames and IEEE 802.3x flow control. Power arrives on 12 to 48 V DC redundant inputs with a 12 W draw, high EFT and ESD protection guard against unregulated voltage, and a relay output rated 24 V DC, 1 A signals a power failure.

Two builds separate the series by temperature. The LNX-1202G-SFP is the standard model, rated -10 °C to 70 °C for heated or indoor cabinets. The LNX-1202G-SFP-T is the extended temperature model, rated -40 °C to 75 °C for unheated and outdoor enclosures. Ports, power and approvals are identical. For eight copper ports and four SFP slots instead, the LNX-1204G-SFP series shifts the balance towards fiber. Choose the -T build for unheated or outdoor enclosures, and the standard build where the cabinet is heated or indoors.

Both LNX-1202G-SFP models come in an IP30 metal case with DIN-rail and wall mounting hardware included, and follow IEC 60068-2-27 shock and IEC 60068-2-6 vibration testing. Antaira lists UL Class 1, Division 2 and UL 61010-1 certification, with FCC and CE marks and RoHS compliance, and covers the series with its 5-year warranty. The LNX-1202G-SFP series is a good fit for cabinets that need 10 gigabit device ports and a pair of fiber uplinks on one DIN rail. In practice, consolidating a cabinet onto one 12-port switch means one redundant power feed, one relay alarm and fewer patch leads to trace when something needs attention.
