FLEXtra Ethernet-Switch

16-Port, unmanaged, 10/100/1000 Mbps

With its compact design, the FLEXtra unmanaged Ethernet switch for up to 1000 Mbit (Gigabit) can be used for a wide range of industrial applications and impresses with its fast data transmission and robust design.

The new Helmholz FLEXtra Ethernet switch unmanaged for up to 1000 Mbit (Gigabit) can be used for a wide range of industrial applications thanks to its very compact design. The lightweight yet robust industrial design is suitable for DIN rail mounting and is very easy to integrate into your network. Once plugged in, it is immediately ready for operation due to the simple plug & play solution. The tool-free push-in connection for the redundant power supply supports you in this.

The practical design with the intelligent arrangement of the Ethernet sockets saves space in the control cabinet. The status LEDs on the top of the FLEXtra Ethernet switch, which are always clearly visible, enable easy diagnostics even when the cabling is full.

The FLEXtra Ethernet switch unmanaged is suitable for PROFINET networks. The LLPD (neighbor detection) and PTCP (time synchronization) functions are handled correctly with the switch according to the PROFINET standard. The FLEXtra Ethernet switch unamanged thus complies with PROFINET Conformance Class A.

Switches with full PROFINET functionality and Conformance Class B can be found here: PROFINET switch 16-port, managed

With the FLEXtra Ethernet switch you can connect up to 16 Ethernet nodes with up to 1000 Mbps. Mixed operation with devices that only support 10 or 100 Mbit is possible without configuration effort. If you want to connect less nodes, we recommend our also available 5/8-port unmanaged Ethernet switches.
