MOTION CONTROL: The slim, compact design and the measurement length of up to 3000 mm make the SG20 and SG30 Wire-Actuated Encoders ideal for space-constrained applications such as crane manufacturing where it is primarily used for measuring the position of the crane support adjustments. This particular area of application requires components with a small footprint to enable simple, cost-effective implementation of redundant measurement systems. An additional advantage of these encoders is the working temperature range of - 40 to 80 to ensure reliable acquisition of measurement data even in extreme weather conditions. This is particularly beneficial to crane systems that often operate in extreme climates. The SG30 also has four independent, lockable aeration holes that help avoid condensation caused by fluctuating temperatures. A solid zinc die-cast housing and spring assembly of fiberglass-reinforced plastic construction give the SG20 and SG30 maximum strength.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
