Antaira LNP-0500 5-Port Fast Ethernet Unmanaged PoE Switches with 4x PoE+ and Extended Temperature Options

A camera on a pole or an access point on a ceiling rarely has a socket beside it, so the switch that feeds its data usually has to feed its power too. The Antaira LNP-0500 series answers that with a five-port industrial unmanaged PoE switch: four PoE+ ports for the devices and one port for the uplink, in a slim IP30 aluminum case that clips onto a DIN rail in the cabinet.

Every LNP-0500 shares the same design. Four 10/100Base-TX RJ45 ports deliver IEEE 802.3at PoE+, with Antaira rating output at 30 W per port from a 51 to 55 V DC supply and 25 W per port at 48 V DC, and a fifth 10/100Base-TX port links the switch to the network. Switching is unmanaged and store-and-forward on a 1.0 Gbps backplane with a 2K MAC address table, auto MDI/MDI-X and broadcast storm protection, so there is no set-up. Redundant 48 to 55 V DC inputs on a 6-contact terminal block let a second supply take over, reverse polarity and overload current protection are built in, and one relay output flags a port break to a PLC or alarm panel.

The series comes in two temperature grades. The LNP-0500 is the standard build, rated -10 °C to 70 °C for heated or indoor cabinets. The LNP-0500-T is the extended temperature build, rated -40 °C to 75 °C for unheated outdoor enclosures. Both carry the same ports, power input and approvals, so the choice comes down to where the cabinet sits. For a 12 to 36 V DC supply the LNP-0500-24 series keeps the same port layout, and the LNP-0500G series moves all five ports to Gigabit.

Antaira lists the LNP-0500 series as UL Class 1 Division 2 and UL 508 certified, with FCC and CE marks and RoHS compliance, and tests it to IEC 60068-2-27 shock and IEC 60068-2-6 vibration. EFT protection to 2,000 V DC and ESD protection to 6,000 V DC guard the ports, and both models carry Antaira’s 5-year warranty. Antaira names security surveillance, ITS traffic monitoring, power and utility facility management, water and wastewater treatment and automated production lines as typical homes for the series, and the -T build takes those jobs into outdoor cabinets.
