Antaira LNX-1604G-SFP 16-Port Unmanaged Gigabit Ethernet Switch with 4 SFP Slots

For systems that test the limits of data processing and reliability, Antaira Technologies created a universal solution with the LNX-1604G-SFP. Available in standard and extended operating temperature models, this Ethernet switch performs for the most demanding applications while enduring extreme environments. It can replace outdated communication components or be added to an existing system, minimizing downtime and related costs.

The LNX-1604G-SFP is centered on reliability. Redundant power inputs and a failure detection relay ensure the switch stays operational even against unregulated power, extreme temperature, dust, and humidity. The DIN-rail mounting is universally compatible making it easy to add the switch to an existing control cabinet or machine.  And, the unmanaged protocol extends that ease by optimizing compatibility. All of this comes in a package that is surge protected up to 6,000 VDC and can operate normally in temperatures between -40° and 75°C. Backed by a 5-year warranty, these are durability claims that can be trusted. On the data side, the LNX-1604G-SFP boasts 12 Gigabit RJ45 Ethernet ports and 4 Gigabit SFP slots, extending the fiber optic possibilities. It will communicate with a wide range of data-intense devices, making it a one-size-fits-all option for nearly any industrial application. It may be used as a single replacement for multiple, smaller devices.  It handles large data loads without showing signs of strain.
