Webexplosion-proof Maximum range Max.: 12 m (39'04") Min.: 0 m (0'00") Description The 92 Ex series sensors are used as diffuse reflection light scanners, through beam photoelectric sensors and retro-reflective sensors. They can efficiently detect objects within a distance range of 300 mm to 12 m. WebLong-life explosion-proof LED lighting that reduces the amount of maintenance. It goes without saying that it would be advantageous to switch over to long-life explosion-proof lighting that can reduce the overall amount of periodic maintenance work. Utilizing our vast experience in explosion-proof safety technology, at IDEC we offer our EF1A ... WebIn the photoelectric effect, light waves (red wavy lines) hitting a metal surface cause electrons to be ejected from the metal. Image from Wikimedia Commons, CC BY-SA 3.0. In this article, we will discuss how 19th century physicists attempted (but failed!) to explain the photoelectric effect using classical physics. This ultimately led to the ... ntut homepage
