The motherboard of a GarrettCom Magnum 6K Series managed switch with conformal coating and special heat sinks is designed to support convection cooling. Both features are important when installing switches in dusty, corrosive, or damp environments. Source: GarrettCom Inc.
There are a number of vendors out there that make what they might call industrial strength Ethernet devices. There is still room for improvement beyond simple temperature and vibration specs. I would like to see something with an IP-67 rating, for instance, so you don't need to enclose everything.
(TJ, I just added a comment to the auto article as well adressing the plastic tab connector concern).
The switch may be industrial, but as I commented in the Ethernet in the car article, the connectors are NOT. RJ45 does not belong in industrial settings; it's time for a new robust connector. M12 Code D might be it. Maybe M8 for higher connector densities?
Jim makes an important point about the lack of interchangeability between commercial routers and switches and industrial ones. The same thing goes for PCs--perhaps even more so. This article talks about hardening mainly in terms of physical hardening -- resistance to temperature extremes and use of conformal coating as protection. The other aspect is that commerical PCs and network gear have subtle differences from model to model, or even in the same generation. This makes the kind of swapping out that's done in the commercial world much more difficult to get away with in industrial settings, where the gear has to work and be up 100%, without having to constantly send in an IT person to tweak settings and diagnose problems.
Earlier this year paralyzed IndyCar drive Sam Schmidt did the seemingly impossible -- opening the qualifying rounds at Indy by driving a modified Corvette C7 Stingray around the Indianapolis Motor Speedway.
Wearables are changing the way we see ourselves. With onboard sensors that have access to our bodies, we are starting to know our physical selves like never before, quantifying our activity, our heart rate, breathing, and even our muscle effort.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
This year, Design News is getting a head start on the Fourth of July celebration. In honor of our country and its legacy of engineering innovation -- in all of its forms -- we are taking you on an alphabetical tour through all 50 states to showcase interesting engineering breakthroughs and historically significant events.
