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.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
