Antaira LNX-C800 8-Port Compact Fast Ethernet Unmanaged Industrial Ethernet Switches with Extended Temperature Options

Eight networked devices in a small panel usually means either a large switch that eats DIN rail or two small ones that double the wiring. The Antaira LNX-C800 series avoids both: small 8-port Fast Ethernet unmanaged industrial Ethernet switches in a small metal case that Antaira designed for integration into projects that need a small footprint, so one switch can serve the whole panel.

Every LNX-C800 shares the same design. Eight 10/100BaseTx RJ45 ports auto-negotiate speed and duplex and support auto MDI/MDI-X, with store-and-forward switching on a 1.6 Gbps fabric, a 1K MAC address table, a 448 Kbit packet buffer and IEEE 802.3x flow control. Redundant 12 to 48 V DC inputs connect through a removable 6-contact terminal block and each switch draws 2.2 W. Reverse polarity protection and a slow-blow overload fuse guard against wiring and supply faults, and LEDs show both power inputs and a fault indicator. The low draw suits small DIN-rail supplies shared with controllers and I/O, and with no management interface there is no configuration to back up, so a spare from stores can replace a failed unit in minutes without a laptop or a saved file.

The series offers two temperature grades. The LNX-C800 is the standard build, rated -10 °C to 65 °C for indoor panels and OEM machines. The LNX-C800-T is the extended temperature build, rated -40 °C to 75 °C for unheated ITS, utility and water treatment cabinets. For gigabit devices the LNX-C800G series offers eight gigabit ports in the same size of case, and the LNX-800A series adds a fault relay and a 24 V AC input option in a slim DIN-rail case.

Both models use an IP30 metal case for a DIN rail, with wall mounting as an option, rated to IEC 60068-2-27 shock and IEC 60068-2-6 vibration. Antaira lists FCC, CE, RoHS and UL 61010-1 certification for the LNX-C800 series and covers it with its 5-year warranty. Antaira names factory automation, ITS, power and utility, and water and wastewater treatment plants as applications, and these small industrial Ethernet switches suit panels in any of them where eight Fast Ethernet links have to share a short length of DIN rail.
