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.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
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.
