ROQSTAR 4GE+12FE M12 Managed Gigabit PoE Switch

4GE + 12FE Managed M12 PoE Gigabit Ethernet Switch

Article number 006-130-125



The ROQSTAR 4GE + 12FE M12 Managed Gigabit Switch was specially developed for applications in buses and trams. The management functions of this Layer 2 switch enable, among other things, network segmentation and monitoring. An easy-to-use web interface and a USB port are available for switch configuration. Furthermore, there is the option of partially automated configuration distribution within an IP network. The integrated NAT function (Layer 3) allows this switch to forward data traffic to different subnets. The integrated PoE power supply delivers up to 96W at 24 VDC to 8 Ethernet ports. A bypass relay ensures that data traffic is maintained in the event of a switch failure in the network. Housed in a metal housing, the M12 connectors ensure stable data transmission despite shock and vibrations that prevail in buses and rail vehicles.

Use Network Cable to Supply Power and Transfer Data

This ROQSTAR 16-Port M12 Managed Gigabit PoE Ethernet Switch supports Power over Ethernet (PoE). You only need a single network cable to both supply power and seamlessly transfer data to connected devices. Eliminating the need for separate power sources reduces clutter and makes installation more straightforward and cost-effective.

Made for Road and Rail

ROQSTAR 16-Port M12 Managed Gigabit PoE Ethernet Switch is both E1 and EN 50155 certifyed. Whether you are designing an IP network in a bus or a tram, this Ethernet switch has been proven to remain stable even in harsh environments and extreme temperatures. 

The E-mark in Public Transport

The EN 50155 Railroad Standard

Made for Interoperability

ROQSTAR 16-Port M12 Managed Gigabit PoE Ethernet Switch is certifyed with the ITxPT label. IT components in buses and trams that are compliant with the regulations of the international association ITxPT are based on an open IT architecture, and therefore compatible with all onboard systems.
