SENSORS: Pepperl+Fuchs introduced RLG28 Retro-Reflective Area Sensors. RLG28 retro-reflective area sensors feature six light beams that generate a constant 60 mm detection fieldto consistently detect objects as small as 12mm in diameter over the entire 0-4m sensing range. They are a perfect sensing solution in material handling and other applications where single beam retro-reflective sensors have reached their functional limitations, or in applications that would otherwise require costly light grids. RLG28 sensors are cULus listed.
With some retro-reflective sensors, shiny objects such as foils, Mylar and certain plastics can be erroneously “seen” as the sensor’s reflector. RLG28 sensors, however, have a polarizing filter that eliminates the potential for such false readings. These retro-reflective area sensors automatically adjust excess gain based on ambient conditions such as lens contamination or temperature changes, enabling constant operation without requiring readjustment. They also offer enhanced status LED indication, better shock and vibration immunity per the international standard EN 60947-5-2, and better low-end temperature rating (to -30C) for freezer/cooler environments.
RLG28 sensors also feature a standard photoelectric sensor housing that is mechanically and electrically compatible with today’s most commonly available photoelectric sensors. As a result, they facilitate fast and easy replacement of single-beam photoelectric sensors.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
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.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
