Antaira LNP-C500G-T 5-Port Compact Gigabit Unmanaged Industrial Ethernet Switch with 4x PoE+ (120W) and -40 to 75 °C

Many panels only need to power a handful of devices, and rail space is often the tightest resource in the enclosure. The LNP-C500G-T is the extended temperature build in the Antaira LNP-C500G series: a small unmanaged industrial PoE switch with four PoE+ ports and one uplink, rated -40 °C to 75 °C for unheated enclosures.

Four 10/100/1000Base-T(X) RJ45 ports follow IEEE 802.3af/at at up to 30 W per port, and a fifth Gigabit RJ45 port carries the uplink, all with auto MDI/MDI-X and auto-negotiation. Switching is store-and-forward with an 8K MAC address table, 10 KB jumbo frames and IEEE 802.3x flow control. There is no management interface, so the switch forwards traffic as soon as it is powered.

Power arrives on redundant 48 to 55 V DC inputs on a removable 4-pin terminal block, with reverse polarity and overload current protection. The 120 W PoE budget covers all four ports at the full 30 W, and the LNP-C500G-T draws 5.5 W itself. Antaira rates surge protection to 2,000 V DC and ESD protection to 6,000 V DC, with high EFT and ESD protection on the power inputs.

The switch sits in a small IP30 metal case for DIN rail mounting, with wall mounting as an option and shock and vibration ratings to IEC 60068-2-27 and IEC 60068-2-6. Antaira names factory automation, ITS, power and utility, and water and wastewater treatment as applications, lists UL 61010-1 certification with FCC, CE and RoHS marks, and backs it with Antaira’s 5-year warranty. The LNP-C500G is the same switch rated -10 °C to 70 °C, the LNP-C501G-SFP-bt moves to 90 W PoE++ with an SFP slot, and the LNX-C500G has five Gigabit ports without PoE.
