Antaira LNX-1204G-SFP 12-Port Unmanaged Ethernet Switch with 8 Gigabit Ports and 4 SFP Slots

For processes that test both the limits of data processing and durability, Antaira has created a universal solution with the LNX-1204G-SFP. Available in a standard and extended temperature model, this switch can spike processing power in the most demanding operations while shrugging off extreme environments. It can replace core components or be added to an existing system, minimizing downtime and related costs in either case.

The LNX-1204G-SFP is centered on reliability. Redundant power input and a failure detection relay input make it easy to insure that the switch stays operational even against heavy vibrations, impacts, extreme temperature, dust and humidity. The DIN mounting is universally compatible making it easy to add the switch to an existing network.  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-1204G-SFP is most impressive with its incorporation of 4 100/1000 SFP ports, extending the fiber optic compatibility of the switch. It can communicate with a wider range of data-heavy devices, making it a one-size-fits-all option for virtually any industrial application. It also works great as a single replacement for multiple, smaller devices, handling the load without showing signs of strain.
