Industrial Grade Design
With its modern, slim, and flat design to minimize surface area usage, this switch series is ideal for demanding industrial applications that require compact solutions to deliver network performance.

Supporting a wide operating temperature range of -40°C to 75°C and being compliant with essential sections of UL/CB(IEC) 62368-1, and MIL-STD-810F, this switch series is a powerful compact device that can perform in various environments under a variety of conditions, such as power input voltage, shock, drop and vibration.


PoE Voltage Booster Option
As part of its compact design, this switch series is available with an optional voltage booster for PoE end devices. Available on the 24V models, the PoE Voltage Boost raises the input voltage of power inputs from as low as 12V to provide Power over Ethernet to end devices. This removes the need for additional, separate power inputs, which can often be costly and space-consuming.
