Antaira LMX-0804G-SFP 8-Port Gigabit Managed Industrial Ethernet Switches with 4x SFP and Extended Temperature Options

Where several fiber runs meet, at a substation, a plant room or the head of a pipeline section, the switch needs more fiber ports than most DIN rail models offer. The Antaira LMX-0804G-SFP series gives an even split: four managed gigabit copper ports and four dual-rate SFP slots in an IP30 metal DIN rail case, so one switch can join a fiber ring and feed spurs to other cabinets.

Both models share one design. The four 10/100/1000Base-TX RJ45 ports support auto MDI, and the four 100/1000 SFP slots take single-mode or multi-mode modules, so wavelength and reach follow the transceivers chosen. Switching is store-and-forward on a 16 Gbps fabric with an 8K MAC table and 9.6 KB jumbo frames. The Layer 2 managed firmware covers IEEE 802.1Q VLANs, QoS, IGMP v1/v2 snooping for up to 256 groups, LACP, LLDP, RMON, port mirroring, DHCP Option 66/67/82, Modbus TCP and 802.1X. ITU-T G.8032 ERPS recovers a ring in under 50 ms, with STP, RSTP and MSTP available.

There are two temperature grades. The LMX-0804G-SFP is the standard build, rated -10 °C to 70 °C for heated or indoor cabinets. The LMX-0804G-SFP-T is the extended temperature build, rated -40 °C to 75 °C for unheated roadside, utility and outstation enclosures. For more copper and fewer fiber ports, the Antaira LMX-1002G-SFP series pairs eight RJ45 ports with two SFP slots.

Antaira names power and utility, water and wastewater, oil, gas and mining, factory automation, ITS and security surveillance within transportation as typical applications for the LMX-0804G-SFP series. Each case is tested for shock to IEC 60068-2-27, vibration to IEC 60068-2-6 and free fall to IEC 60068-2-32, with storage from -40 °C to 85 °C and 5% to 95% non-condensing humidity. Redundant 12 to 48 V DC inputs land on a 6-contact terminal block with overload and reverse polarity protection and a 15 W draw, exceptions can trigger an e-mail or relay output, and high EFT and ESD protection is built in. The series is UL 61010-1 certified, carries FCC and CE marks and comes with Antaira’s 5-year warranty, and we can pre-configure VLANs and ring settings before dispatch.
