Did you know Westermo managed switches and routers can be installed from the North Pole to the Sahara desert as standard?

As standard, the Westermo range of managed switches and routers have a true temperature specification from -40 to +70°C. There are no special part numbers or long lead times while a temperature specific devices is manufactured. The temperature specification listed is the actual ambient temperature the devices can be subjected to and continue to operate in without interruption. Not only can the devices continue to operate at this extreme temperature, but they have also passed the cold start testing where the device is held unpowered at -40°C for 16 hours and then powered up. Starting from this very cold temperature creates conditions inside the housing where dew can form when the electronics starts to heat up.

If the electronics is not designed from the start to cope with these extreme conditions, the dew can cause short circuits on the PCB and the device will failure to boot correctly. Components not certified for industrial use in extreme cold temperature can also be damaged when started at -40°C. The component enclosure can crack, or the stated value of the component has changed, letting higher than normal level of current to flow causing the component or surrounding electronics to be damaged.

At the opposite end of the spectrum, the Westermo switches and routers can be continuously subjected to an ambient +70°C with little effect on the expected service life. Individual lines have been tested to even more extreme temperature conditions from -50°C up to 85°C.
