Antaira LNX-C501G-SFP 5-Port Compact Gigabit Unmanaged DIN Rail Switches with 1x SFP and Extended Temperature Options

Copper Ethernet stops at 100 m and is easily disturbed near drives and power cables, so the run from a remote cabinet back to the control room often has to be fiber. The Antaira LNX-C501G-SFP series handles that with one small unit: 5-port gigabit unmanaged DIN rail switches with four copper ports for local devices and one SFP slot for the fiber uplink.

Every LNX-C501G-SFP shares the same design. Four 10/100/1000Base-TX RJ45 ports support auto-negotiation and auto MDI/MDI-X, and the dual-rate SFP slot takes a 100 or 1000 Mbps transceiver, with a DIP switch to set the speed so the switch can meet an older Fast Ethernet fiber link. Store-and-forward switching runs on a 10 Gbps fabric with an 8K MAC address table, a 1 Mbit buffer, 10K jumbo frames and IEEE 802.3x flow control. Redundant 12 to 48 V DC inputs connect through a removable 6-contact terminal block with reverse polarity protection and a slow-blow fuse, each switch draws 4.6 W, and a relay contact rated 24 V DC at 1 A sits beside a fault LED. Because the SFP slot takes standard modules, the same switch can serve a short multi-mode run on one site and a long single-mode run on another.

The series offers two temperature grades. The LNX-C501G-SFP is the standard build, rated -10 °C to 65 °C for heated or indoor cabinets. The LNX-C501G-SFP-T is the extended temperature build, rated -40 °C to 75 °C for unheated outdoor enclosures. For an all-copper switch in a small case, the LNX-C500G series offers five gigabit RJ45 ports, and the LNX-0501G-SFP series is a slim alternative with the same port mix.

Both models use an IP40 metal case for a DIN rail or a wall, with high EFT and ESD protection. Antaira lists FCC, CE and UL 61010-1 approvals for the LNX-C501G-SFP series and covers it with its 5-year warranty. Antaira names power and utility, water and wastewater, oil, gas and mining, factory automation, security surveillance and ITS among the applications, and these DIN rail switches suit any site where a machine, camera cabinet or remote panel sits too far from the core for copper alone.
