Antaira LNP-0702C-SFP-24-T 7-Port Fast Ethernet Unmanaged Industrial PoE Switch with 4x PoE+, 2x SFP, 12-55V DC Input and -40 to 75 °C

Plenty of cabinets and enclosures only have a 12 or 24 V DC supply, which rules out a switch that needs 48 V to deliver PoE. The LNP-0702C-SFP-24-T is the extended temperature build in the Antaira LNP-0702C-SFP-24 series: a 7-port unmanaged PoE+ switch for DIN-rail cabinets, with PoE+ copper for local devices and fiber for the link back to the network core. Antaira designs it for rugged, harsh industrial environments.

It has four 10/100Base-TX RJ45 ports with IEEE 802.3af/at PoE+ at up to 30 W each, one further 10/100Base-TX port without PoE, plus two 100/1000 dual-rate SFP slots, so the fiber type and reach follow the transceiver fitted. Switching is unmanaged and store-and-forward, on a 5 Gbps switching fabric with an 8K MAC address table, 9.6 KB jumbo frames and a 4 Mbit memory buffer, and IEEE 802.3x flow control. There is nothing to set up: traffic flows as soon as the switch is powered.

Power arrives on 12 to 55 V DC redundant inputs on a removable terminal block. The PoE budget depends on input voltage: 60 W at 12 V DC rising to 120 W from 36 to 55 V DC, so a 48 V supply covers all four ports at 30 W. One relay output, rated 24 V DC at 1 A, gives a power failure warning to a PLC or alarm panel. Reverse polarity protection and overload current protection with a slow-blow fuse guard the input side.

The LNP-0702C-SFP-24-T operates from -40 °C to 75 °C in an IP30 metal case for DIN-rail mounting, with wall-mount hardware included. Shock and vibration are rated to IEC 60068-2-27 and IEC 60068-2-6. Antaira lists it as UL Class 1 Division 2 and UL 61010-1 certified, with CE and FCC marks and RoHS compliance, and it is covered by Antaira’s 5-year warranty. The LNP-0702C-SFP-24 is the standard build rated -10 °C to 70 °C, the LNP-0702C-SFP takes a 48 to 55 V DC input, and the LNP-0702G-SFP-24 moves all five copper ports to gigabit.
