Antaira LMX-0501G-SFP-V2 5-Port Gigabit Managed Industrial Ethernet Switches with 1x SFP and Extended Temperature Options

Copper Ethernet runs out at 100 m and picks up interference near drives and power cables, so the link from a remote cabinet back to the control room is often fiber. A managed switch at that cabinet also gives the SCADA team VLANs, ring protection and something to poll. The Antaira LMX-0501G-SFP-V2 series combines both: four managed gigabit copper ports and one SFP slot for the fiber uplink, in an IP30 metal case for a DIN rail.

Both models share the same Version 2 hardware. The four 10/100/1000Base-T(X) RJ45 ports support auto MDI/MDI-X, and the SFP slot takes a 100 or 1000 Mbps transceiver, so the fiber type and reach follow the module chosen. Switching is store-and-forward on a 10 Gbps fabric with an 8K MAC table and 9.6 KB jumbo frames. The Layer 2+ firmware covers IEEE 802.1Q VLANs, QoS, IGMP snooping for up to 1024 groups, LACP, SNMP v1/v2c/v3, RMON, Modbus TCP and 802.1X, and adds static routes between VLANs with DHCP Option 82. 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-0501G-SFP-V2 is the standard build, rated -10 °C to 70 °C for heated or indoor cabinets. The LMX-0501G-SFP-T-V2 is the extended temperature build, rated -40 °C to 75 °C for unheated outdoor enclosures, pumping stations and roadside cabinets. For a fifth copper port, the Antaira LMX-0601G-SFP-V2 series follows the same design.

Antaira names power and utility, water and wastewater, oil, gas and mining, factory automation, security surveillance and ITS as typical applications. 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 reverse polarity and overload protection, a 24 V DC relay contact and a 7.5 W draw, and high EFT and ESD protection is built in. The LMX-0501G-SFP-V2 series carries FCC and CE marks, is RoHS compliant and comes with Antaira’s 5-year warranty, and we can pre-configure IP addressing, VLANs and ring settings before it ships.
