Antaira LNX-C800G 8-Port Compact Gigabit Unmanaged Industrial Network Switches with Extended Temperature Options

A small panel that hosts several gigabit cameras, controllers or data loggers needs more than a Fast Ethernet switch, but it rarely has room for a large one. The Antaira LNX-C800G series fits eight gigabit ports into a small footprint: 8-port gigabit unmanaged industrial network switches in a small metal case that Antaira designed for integration into projects and equipment where every centimeter of rail counts.

Every LNX-C800G shares the same design. Eight 10/100/1000BaseTx RJ45 ports auto-negotiate speed and duplex and support auto MDI/MDI-X. Store-and-forward switching runs on a 16 Gbps fabric, enough for every port at full gigabit speed, with a 4K MAC address table, a 512 Kbit buffer, 9,216-byte jumbo frames and IEEE 802.3x flow control. Redundant 12 to 48 V DC inputs connect through a removable 6-contact terminal block, each switch draws 4 W, and reverse polarity protection and a slow-blow overload fuse are built in, with LEDs for both power inputs and a fault indicator. Jumbo frames help with large image and data transfers, the 4 W draw suits small DIN-rail supplies shared with other equipment, and with no management interface there is no configuration to back up, so a spare from stores can replace a failed unit in minutes.

The series has two temperature grades. The LNX-C800G is the standard build, rated -10 °C to 65 °C for indoor panels and OEM equipment. The LNX-C800G-T is the extended temperature build, rated -40 °C to 75 °C for unheated ITS, utility and water treatment cabinets. The LNX-C800 series is the Fast Ethernet equivalent, the LNX-800AG series adds a power-fail relay in a slim DIN-rail case, and the LNP-C800G series adds PoE+ on all eight ports.

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-C800G 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. Where eight gigabit links have to fit a tight panel with no set-up, these industrial network switches are a good fit.
