Antaira LNX-0501G-SFP 5-Port Industrial Gigabit Unmanaged DIN-Rail Ethernet Switches with SFP Fibre Slot

Copper Ethernet runs out at 100 m and picks up interference near drives, welders and power cables, so the link from a remote cabinet back to the control room often has to be fibre. The Antaira LNX-0501G-SFP series handles that in one slim unit: an industrial unmanaged Ethernet switch with four copper gigabit ports for local devices and one SFP slot for a fibre uplink, in a 30 mm wide IP30 aluminium case for a DIN rail.

Every LNX-0501G-SFP shares the same design. 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 fibre type and reach follow the module chosen. Switching is unmanaged and store-and-forward, on a 10 Gbps switching fabric with an 8K MAC address table and 9.6 KB jumbo frame support, with broadcast storm protection built in. Ports are protected against surges to 3,000 V DC and ESD to 6,000 V DC, and one relay output signals a port break to a PLC or alarm panel.

The series offers two temperature grades. The LNX-0501G-SFP is the standard build, rated -10 to 70 °C for heated or indoor cabinets. The LNX-0501G-SFP-T is the extended temperature build, rated -40 to 75 °C for unheated outdoor enclosures, trackside cabinets and cold stores. For an all-copper switch with five RJ45 ports, the LNX-500AG series is the nearest Antaira alternative.

Power arrives on 12 to 48 V DC redundant inputs on a 6-pin terminal block, so a second supply can take over if the first fails, and the switch draws 5 W. Both models measure 30 x 99 x 142 mm, mount on a DIN rail and include a wall-mount bracket. Antaira lists the series as UL Class I, Division 2 certified, with FCC and CE marks, and backs it with its 5-year warranty. Antaira does not name specific applications; the fibre slot makes it a good fit where a machine or kiosk sits far from the network core or near heavy electrical plant, and the -T build carries that to unheated outdoor sites such as roadside cabinets, pumping stations and trackside enclosures.
