The contrast sensor triggers the ink jet printer, and ensures that the address field is printed as the envelopes move along the belt. The envelope printing is triggered by a separate print mark, which is colored in weak contrast to the envelope itself. The two shades of yellow (print mark and envelope) are easily recognized by the DK12 contrast sensor.

  • Photoelectric Effect and Photoelectric Cell Check us out at The photoelectric effect is a phenomenon in which electrons are emitted from matter (metals and non-metallic solids, liquids or gases) as a consequence of their absorption of energy from electromagnetic radiation of very short wavelength, such as visible or ultraviolet light. Electrons emitted in this manner may be referred to as "photoelectrons".As it was first observed by Heinrich Hertz in 1887, the phenomenon is also known as the "Hertz effect", although the latter term has fallen out of general use. Hertz observed and then showed that electrodes illuminated with ultraviolet light create electric sparks more easily. The photoelectric effect takes place with photons with energies from about a few electronvolts to, in high atomic number elements, over 1 MeV. At the high photon energies comparable to the electron rest energy of 511 keV, Compton scattering, another process, may take place, and above twice this (1.022 MeV) pair production may take place. Study of the photoelectric effect led to important steps in understanding the quantum nature of light and electrons and influenced the formation of the concept of waveparticle duality. The term may also, but incorrectly, refer to related phenomena such as the photoconductive effect (also known as photoconductivity or photoresistivitity), the photovoltaic effect, or the photoelectrochemical effect which are, in fact, distinctly different.

  • The Photoelectric Effect - A Simple Experiment w/ UV Photons How can light discharge the tinsel?! Try this experiment! Tinsel, a negatively charged PVC pipe, an aluminum cake pan and an ultraviolet light (germ sanitizer) are used to demonstrate the photoelectric effect. In a nutshell, the photoelectric effect is the emission of electrons when a surface is exposed to photons of sufficient energy. Note that the effect is frequency dependent. Electrons will be emitted if the photon frequency equals or exceeds the threshold frequency for the metal. One could shine a 100 watt Helium Neon laser on the aluminum pan without discharging the tinsel. In contrast, when UV photons strike the pan, they are quickly absorbed and readily release electrons. A few tips: PVC pipe works great for giving the tinsel a static charge. Note, however, that not all tinsel will work properly. It must be electrically conductive and light weight. If the tinsel continues to cling to the PVC pipe, it is probably not conductive enough. See "tips and secrets" at the end of the video for further details. Note that this experiment works ONLY when the tinsel is given a negative charge. For best results, place the apparatus on top of an insulating material, such as a thick sheet of plexiglass or rubber. Also note that it was necessary to lightly scrub the surface of the aluminum pan, to expose the bare metal. Going further: Try other metals. Try electrolytes, coatings, various frequencies of light. Ponder how you might use this knowledge to design a solar cell. Share ...

  • The Photoelectric Effect This is a demonstration of the photoelectric effect. In the photoelectric effect, electrons are emitted from a metal when light is shone on it, providing that the photon energy is greater than the workfunction of the metal (ie, the amount of energy needed to rip an electron away from its atom). This demo is really fussy about humidity, so it often doesn't work, and the video is a cut from more than one take due to some misbehaviour with the experiment. But still, it worked better than it often does. Video posted for use under Creative Commons Licence - by-nc-sa

  • Pepperl+Fuchs SBL8 Photoelectric Sensor Pepperl+Fuchs SBL8 photoelectric sensors prevent product damage caused by a congested conveyor. In this application, a queue leads to a roller conveyor. In this queue, it is important that the containers are transported without pressure, which means that one container must not push on the one in front. The SBL8-H roller conveyor control with backround suppression, located directly between the rollers of the conveyor, prevents piece goods from colliding. Direct control of valves as well as cascading of several sensors is possible. These sensors are optionally equipped with a magnetic valve to control material flow directly. By linking the voltage supply, the electric signal and the compressed air, the installation outlay is minimal. For technical information on Pepperl+Fuchs products, please visit Steven Engineering at
