Antaira LNX-C500-T 5-Port Compact Fast Ethernet Unmanaged Industrial Network Switch with -40 to 75 °C

Traffic cabinets, water treatment enclosures and utility boxes are often small, unheated and already full of equipment. The LNX-C500-T is the extended temperature model in the Antaira LNX-C500 series, rated -40 °C to 75 °C: a five-port Fast Ethernet unmanaged industrial network switch in a small metal case for those cabinets.

Five 10/100BaseTx RJ45 ports auto-negotiate speed and duplex and support auto MDI/MDI-X. Store-and-forward switching runs on a 1 Gbps backplane with an 8K MAC address table, a 448 Kbit packet buffer and IEEE 802.3x flow control. There is no set-up: the switch passes traffic once it is powered, so a field technician can swap one in without a laptop.

Redundant 12 to 48 V DC inputs land on a removable 4-contact terminal block, and the switch draws 1.2 W, which leaves headroom on a small cabinet supply. Reverse polarity protection keeps the unit off if the wiring is reversed, overload current protection is built in, and the ports are protected against surges to 2,000 V DC and ESD to 6,000 V DC.

The IP30 metal case mounts on a DIN rail, or on a wall as an option, and is rated to IEC 60068-2-27 shock and IEC 60068-2-6 vibration. Antaira lists FCC, CE, RoHS and UL 61010-1 certification, NEMA TS2 compliance and its 5-year warranty for the LNX-C500-T, and names factory automation, ITS, power and utility, and water and wastewater treatment as applications. The LNX-C500 is the standard build rated -10 °C to 70 °C, and the LNX-C500-T-CC adds conformal coating for damp or corrosive cabinets.
