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.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
