Antaira LNP-1204G-SFP-T 12-Port Gigabit Unmanaged PoE Switch with 8x PoE+ (240W), 4x SFP and -40 to 75 °C

Two fibre ports are enough for a single uplink, but a cabinet that joins a ring, feeds neighbouring cabinets or needs a spare path quickly wants more. The LNP-1204G-SFP-T is the extended temperature build in the Antaira LNP-1204G-SFP series: an unmanaged industrial PoE switch with four SFP slots alongside eight PoE+ ports, rated -40 °C to 75 °C.

The eight 10/100/1000Base-T(X) RJ45 ports follow IEEE 802.3af/at at up to 30 W per port, and the four dual-rate 100/1000 SFP slots accept multi-mode or single-mode transceivers, so each fibre link can be sized to its own distance. Switching is store-and-forward on a 24 Gbps fabric with an 8K MAC address table, 9.6 KB jumbo frames and IEEE 802.3x flow control. With no management interface, it forwards traffic as soon as it is powered.

Power arrives on redundant 48 to 55 V DC inputs on a removable 6-pin terminal block, with reverse polarity and overload current protection and high EFT and ESD protection. The 240 W PoE budget covers all eight ports at the full 30 W, and the LNP-1204G-SFP-T draws 10 W itself. A relay output rated 1 A at 24 V DC warns a PLC or alarm panel when a supply fails.

The switch sits in an IP30 metal case for DIN rail or wall mounting, with shock and vibration ratings to IEC 60068-2-27 and IEC 60068-2-6. Antaira names security surveillance, traffic monitoring, power and utility, water and wastewater treatment, oil, gas and mining, and GigE machine vision in factory automation as typical applications, lists UL 61010-1 certification with FCC, CE and RoHS marks, and covers it with Antaira’s 5-year warranty. The LNP-1204G-SFP is the same switch rated -10 °C to 70 °C, the LNP-1202G-SFP has two SFP slots plus two RJ45 ports, and the LNX-1204G-SFP keeps four SFP slots without PoE.
