The following are some examples of applications for which particular attention must be given. This is not intended to be an exhaustive list of all possible
uses of the products, nor is it intended to imply that the uses listed may be suitable for the products:
Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in this catalog.
Nuclear energy control systems, combustion systems, railroad systems, aviation systems, medical equipment, amusement machines, vehicles,
safety equipment, and installations subject to separate industry or government regulations.
Systems, machines, and equipment that could present a risk to life or property.
