Antaira LNP-1604G-SFP 16-Port Gigabit Unmanaged DIN Rail Switches with 12x PoE+ (240W), 4x SFP and Extended Temperature Options

Fiber rings and cabinet-to-cabinet links are how large industrial sites stay connected over distance, and every cabinet on such a network needs several fiber ports as well as powered copper ports for its cameras and access points. The Antaira LNP-1604G-SFP series combines both in one unmanaged industrial PoE switch for a DIN rail, with 12 PoE+ ports and four SFP slots. With four fiber ports, one switch can hold a ring pair and still feed two more cabinets, so the network grows without adding a separate fiber switch at each junction.

Every LNP-1604G-SFP shares the same design. The 12 10/100/1000Base-T(X) RJ45 ports follow IEEE 802.3at at up to 30 W per port, and the four dual-rate 100/1000 SFP slots take multi-mode or single-mode transceivers, so each fiber run can be sized to its own distance. The 240 W PoE budget is shared, covering eight ports at the full 30 W or all 12 at an average of 20 W. Switching is store-and-forward on a 32 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-1604G-SFP is the standard build, rated -10 °C to 65 °C for heated or indoor cabinets. The LNP-1604G-SFP-T is the extended temperature build, rated -40 °C to 75 °C for unheated enclosures exposed to outdoor temperatures. For 16 PoE+ ports with the same four SFP slots, the LNP-2004G-SFP series is the next size up.

Antaira names security video surveillance, GigE machine vision, process control automation and intelligent transportation as typical applications for the LNP-1604G-SFP series. Twelve PoE+ ports suit a typical mid-sized camera or access point 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 backs them with its 5-year warranty, and our team can help match SFP modules to each fiber run and check the planned PoE load against the budget.
