This week's EYE ON NPI can handles whatever the weather throws at it -
with the Stewart IP67 Rated USB Type-A Cable Assemblies
(https://www.digikey.com/en/product-highlight/s/stewart-connector/ip67-rated-usb-type-a-cable-assemblies).
I absolutely adore using common, off-the-shelf connectors and hardware -
like a Raspberry Pi or Arduino - for hardware designs. But, of course,
most hardware you buy is not weather-proofed by default because it's
expensive and restrictive. So instead, often times the final integration
step is where durability is added by the designers. That's where these
cables come in.
Instead of re-designing or re-building your existing cable connectors to
use specialized weatherproof contacts, here we are supporting the common USB type A cables that are used everywhere for connecting accessories to your single-board computer. Now you can tuck away the Raspberry Pi or BeagleBone you've got in any enclosure you fancy.
The Stewart IP67 cables come in a few different flavors, so you'll want
to mix and match the right kinds to get the ends and threading right.
For example, there's USB 2

and USB 3
(https://www.digikey.com/en/products/detail/stewart-connector/67U3AA-006-K/14300411),
USB Type A plug
(https://www.digikey.com/en/products/detail/stewart-connector/67U2AD-006-K/14300402)
and Type A socket
(https://www.digikey.com/en/products/detail/stewart-connector/67U2BD-006-K/14300407),
and you can get them with cut ends or connector ends.
These cables come with an environmental rating (e.g.
weather/waterproofing rating) so you know exactly what kind of use cases
they are safe for - otherwise known as an IP rating
(https://www.iec.ch/ip-ratings) IP67 means that the connector, once
properly installed is completely dust-tight (that's the 6, maximum
rating possible) and protected against rain, jets of water, and even
temporary water immersion. That's the 7 part in IP67. It's not meant for
being dunked in water for extended periods of time - like in a pool or
aquarium - you'll need IP68 for that. Of course, the higher the rating
the more expensive the connectors. Compare the rating to every day
electronics which naturally have an IP rating of maybe IP30, with only
the most basic dust prevention and no water protection.
