Antaira LNP-1204G-SFP 12-Port Gigabit Unmanaged PoE Switches with 8x PoE+ (240W), 4x SFP and Extended Temperature Options

Fiber is what lets a camera or machine cabinet sit hundreds of meters from the control room, and once a site starts building rings or daisy-chaining cabinets, two fiber ports run out quickly. The Antaira LNP-1204G-SFP series gives each cabinet four SFP slots alongside eight PoE+ ports, in one unmanaged industrial PoE switch for a DIN rail. The extra slots let a cabinet take a primary and a spare uplink, or pass fiber on to the next cabinet in a chain, without adding a separate fiber switch.

Every LNP-1204G-SFP shares the same design. The eight 10/100/1000Base-T(X) ports follow IEEE 802.3af/at at up to 30 W per port, within a 240 W budget that covers all eight at full load. The four dual-rate 100/1000 SFP slots take multi-mode or single-mode transceivers, so each run can be sized to its distance. Switching is store-and-forward on a 24 Gbps fabric with an 8K MAC table and 9.6 KB jumbo frames, and there is nothing to configure. Power arrives on redundant 48 to 55 V DC inputs on a 6-pin terminal block, with a power-failure relay, reverse polarity and overload current protection, and high EFT and ESD protection.

The series comes in two temperature grades. The LNP-1204G-SFP is the standard build, rated -10 °C to 70 °C for heated or indoor cabinets. The LNP-1204G-SFP-T is the extended temperature build, rated -40 °C to 75 °C for unheated enclosures exposed to outdoor temperatures. If two fiber ports are enough and the cabinet also needs two wired Gigabit ports without PoE, the LNP-1202G-SFP series is the closer fit, and the LNX-1204G-SFP series keeps four SFP slots where no device needs PoE.

Antaira names security surveillance, traffic monitoring, facility management in power and utility, water and wastewater treatment, oil, gas and mining, and GigE machine vision in factory automation as typical applications for the LNP-1204G-SFP series. Both builds sit 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, UL 61010-1 certification and FCC, CE and RoHS marks. Antaira backs them with its 5-year warranty, and our team can help choose SFP modules to match each fiber run.
