Antaira LNP-1802G-SFP 18-Port Gigabit Unmanaged Industrial Ethernet Switches with 16x PoE+ (240W), 2x SFP and Extended Temperature Options

Large camera schemes tend to gather many devices in a few cabinets, then send everything back to the control room over fiber. The Antaira LNP-1802G-SFP series is sized for that pattern: an unmanaged industrial PoE switch with 16 PoE+ ports for the devices and two SFP slots for the uplink and a second path, all on one DIN rail. Putting 16 powered ports and the fiber uplink in one unit leaves more room in the cabinet and fewer separate supplies to wire and maintain.

Every LNP-1802G-SFP shares the same design. The 16 10/100/1000Base-T(X) RJ45 ports follow IEEE 802.3at at up to 30 W per port, and the two dual-rate 100/1000 SFP slots take multi-mode or single-mode transceivers, so reach follows the module fitted. The 240 W PoE budget is shared, covering eight ports at the full 30 W or all 16 at an average of 15 W, which suits many fixed cameras. Switching is store-and-forward on a 36 Gbps fabric with an 8K MAC table, 9.6 KB jumbo frames and a 4 Mbit buffer, with nothing to configure. Power arrives on redundant 48 to 55 V DC inputs on a 6-pin terminal block, with a supply-failure relay, a slow-blow fuse, reverse polarity protection and high EFT and ESD protection.

The series comes in two temperature grades. The LNP-1802G-SFP is the standard build, rated -10 °C to 65 °C for heated or indoor cabinets. The LNP-1802G-SFP-T is the extended temperature build, rated -40 °C to 75 °C for unheated enclosures exposed to outdoor temperatures. Where the cabinet needs four fiber ports, the LNP-2004G-SFP series adds two more SFP slots, and the LNX-1802G-SFP series keeps the same layout without PoE.

Antaira names security video surveillance, GigE machine vision, process control automation and intelligent transportation as typical applications for the LNP-1802G-SFP series. The second SFP slot can carry a spare uplink or a link to a neighboring cabinet. 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 covers them with its 5-year warranty, and our team can help check the planned PoE load and pick SFP modules for the fiber run.
