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.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
Researchers at MIT and Sandia National Labs have observed a reaction in lithium-air batteries that could help improve the design of these cells for electric vehicles and other applications.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
