Antaira LMP-1204G-SFP-bt 12-Port Managed Switch with 8 Gigabit PoE++ Ports and 4 SFP Slots

If you need an industrial-grade managed Ethernet switch that can deliver both data and power (up to 90 W of power over Ethernet), the LMP-1204G-SFP-bt from Antaira is an impressive choice. This is a highly reliable Ethernet switch suitable for extreme temperatures and offers class-leading protection from voltage and current spikes.

Because of its reliability and ability to withstand harsh conditions, it’s a prime choice for powering and connecting security cameras and other PoE devices — no matter the hazards your facility or outdoor space can throw at them. If your environment exceeds the generous standard range (-10°C to 65°C), note the T configurations below that boast an extended operating temperature of -40 to 75°C.

All models featuring the -bt designation meet the latest PoE specification, ensuring that even the newest PoE equipment will operate well when connected to this managed Ethernet switch. This unit is also flexible: as a DIN rail-mounted unit, it fits in control cabinets, allowing you to integrate it into your existing setup with ease.

The LMP-1204G-SFP-bt series is preloaded with an intuitive web management console for easy access and configuration. It also offers high EFT and ESD protection. Whatever your industrial networking applications — be it power, utilities, factory, security surveillance, or other outdoor or harsh environments — this Ethernet switch has the protection you need. Antaira’s LMP-1204G-SFP-bt is equipped with a five-year warranty, giving you peace of mind that your investment will function well for years to come.
