FL SWITCH 1605 device mounted on profiles

Unmanaged switches 1600 and 1700

With the unmanaged IP67 switches of the 1600 and 1700 series, you can connect up to eight Ethernet-capable network devices directly in the field. The version of the unmanaged switch with the higher IP67 degree of protection makes it resistant to external influences such as moisture and dust. Robust field devices, for example I/O modules, can therefore be integrated locally, directly in the machine on the network. In this case, the Plug and Play capability enables uncomplicated installation without configuration outlay. To make sure that the cabling is also protected against harsh ambient conditions, both the power supply and the network connections are designed using the standardized M12 connection method which is suitable for use in the field.

The FL SWITCH 1605 is particularly suitable for use in machines

Problem-free use in automation networks

The unmanaged IP67 switches of the 1600 and 1700 series are suitable for use in networks in which automation protocols such as PROFINET, EtherNet/IP™, or Modbus/TCP are used. Support of the Quality of Service function in accordance with the ​IEEE 802.1Q standard is the basis for ensuring that data traffic with a higher priority, such as time-sensitive process data, is not obstructed by low-priority data packets in the event of heavy data traffic. The unmanaged switch therefore guarantees real-time capability in PROFINET networks. With a data rate of up to 1000 Mbps, the switch also provides sufficient transmission speed for communication with modern field devices such as I/O stations, controllers, and high-speed cameras.

IP67 switch mounted on a structural profile

With an overall width of just 30 mm, the IP67 switch 1605 is extremely narrow

Flexible choice of mounting location

The IP67 switch 1605 ensures a high level of flexibility when selecting the mounting location. As the overall width of the switch is just 30 mm and it can be fastened with just two M6 screws, it can, for example, be mounted directly on the structural profiles of the machines. This dispenses with laborious time-consuming preparation and attachment of mounting plates. The version of the unmanaged switch with IP67 degree of protection and a broad temperature range of -40°C to +70°C also allows mounting in harsh ambient conditions.

M12 push-pull connection

M12 push-pull connections offer quick and easy connections with one click

Fast and easy connection using M12 push-pull technology

The unmanaged switches FL SWITCH 1608 and 1708 feature the M12 push-pull fast-locking system to easily secure your network connection with just one click. With it, you can secure your network connection with just one click. The tool-free locking element offers significant advantages during installation in confined spaces or when the mating connector is difficult to see.

These switches also provide easy power distribution with two built-in power connections per switch, allowing extended line topologies to be realized.

Mobile applications

Thanks to its compact design and robust construction, the unmanaged IP67 switches of the 1600 and 1700 series are also suitable for mobile applications such as robotic tools, transport systems, and vehicle applications. Thanks to its broad input voltage range, operation in vehicles with a 12, 24, or 48 V DC electrical system is possible. The switch’s low current consumption also makes it suitable for operation in battery-driven applications.
