This channel is really a treasure I found in youtube for instrumentation, simple animation with most clear explanation and easy to understand in one go, really awesome thanks a lot for this
Thanks for this great video! I manage a supply chain for a packaging OEM and videos like this help me learn about our applications (aside from me bugging our engineers lol)
Do Photoelectric work well outdoors in the rain / snow? Looking for a sensor (PIR, beam break etc) to watch a gate and trigger an output when cars drive through
Thank you for your question. Yes, they do work in different environments. These devices are made for outside and inside use. You must order the correct one for your application and environment. They are manufactured with an IP rating. I am including a RealPars RU-vid video for your review and for learning about IP ratings. I would suggest you contact your local vendor. Here are some links for your learning. There are many companies on the Internet you can choose from. www.keyence.com/products/sensor/vision-sensor/ ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-z935clBMJYU.html Happy learning!
Video is very useful . can photoelectric sensors be used to measure the dimension like diameter and width of the object ? If yes what sotware and hardware needed
Hi there, Thank you for your question! If engineered correctly, and you are using a PLC, you can. I mentioned again if engineered correctly, use a photocell to measure the width of a physical object, and you can use a photocell to make dimensional measurements of an object. Still, you will have to use a robot and, in some cases, more than one photocell. But there are better devices like camera imaging that are more cost-effective and used in the market. Regarding the software, too many are out in the market that can do this for you. Too many to mention. But below are some links to 2 companies with lots of reading material for your learning experience. www.keyence.com/products/sensor/photoelectric/ www.omega.com/en-us/ Happy learning!
There are retro-reflexive sensors (Sick) and diffuse reflective sensors (Omron) that are made for this very purpose. Check with the manufacturer before purchasing to make sure the sensor is appropriate for your application.
Thank you for your question! Yes, it can. It's always a good idea to consult the manufacturer’s data sheet to ensure it fits your application. Here’s a link to a company that manufactures these sensors. Keep in mind that this is just one option among many, depending on your location. www.keyence.com/products/ Happy learning!
Thank you for reaching out. Certainly, there are sensors available that can read numerical data and transmit it in the required format, though they often come with a corresponding cost. It's important to note that the content we provide in our lessons primarily caters to the automation industry rather than hobbyist endeavors, in case that's what you're seeking. However, if you're interested in learning more about sensors and their functionalities, I recommend exploring this link to a prominent company in the field. It could offer valuable insights into sensor technologies and applications. www.keyence.com/products/
Hi Mohammed, The length of the sensor can differ based on the manufacturer and the intended application. To find specific details, I recommend referring to the data sheet of the through-beam sensor model you're considering for your application. Here are some links that provide information relevant to your needs. Keep in mind that the choice depends on the specific application. www.keyence.com/products/sensor/ us.rs-online.com/view/search/?category=2%7c3882615%2f3886757 Enjoy your learning experience with RealPars!
Hi Travis, You can share/use our video as long as it remains unmodified, tagged and credited back to us. You can go ahead and embed our video in your teaching materials, but any modification or translation is not allowed. Hope this helps! If you have any other questions or concerns, please feel free to reach out to us over at hello@realpars.com
Thanks. I really like the simple style and technical nature of your videos. I will make sure the video content is unaltered with a card giving Real pads credit for the production.
If you mean starting/stopping a DC motor when an object passes through the retroreflective beam, then yes, but you will need to use a relay. A retroreflective sensor does not have a sufficient power rating to control a motor.
Light from a shiny object certainly could bounce back to a retroreflective sensor, but most of the time, this type of detector is used for corrugated boxes, and other non-shiny surfaced objects. Another plus is the reflector bounces the emitted beam back to the receiver at an angle, so it is much less likely for a passing bottle or part to be able to reflect the light to the receiver at that same angle, giving a false signal.
hi, how can this type of sensors can detect materials such as metals, wood, plastic and etc. ? can I use this type of sensors for material recognition system ?
This is a popular question. There are many different types of sensors which can detect objects of different materials. A block of wood, a cardboard box and many plastics can be detected with a through-beam or retroreflective sensor. Glass, opaque plastic, and sheet film can use diffused sensors if the material significantly refracts the light beam. There some very sophisticated (and expensive) LED-based sensors that can differentiate between different types of plastic sheets (PET, LDPE, HDPE, PVDF, etc.).
Great content!, I would like to do some animated videos like these in spanish, can you tell me what is the program you use to animate please?, keep up the good work!!
Hi there, Thanks for your comment and compliment! I am actually not sure about this, our animations are created by our Graphic and Animation department.
Do these exist in scaled down versions?, just trying to use a photoelectric sensors for a project and was wonderingif you can find them in smaller sizes
Yes. They are traditionally called "miniature sensors." As an example, here is the catalog page for DigiKey photoelectric sensors. Enter "mini" into the "Search within results" bar at the top of the page. You will find a wide array of small sensors available. Other manufacturers have extensive catalogs as well. For any that you select, double check the specifications to insure it will meet your requirements for voltage, sensing distance, etc. Happy shopping!
Great question! That would actually make for a great future course video, I have happily gone ahead and passed this on to our course developers. Thanks for sharing and happy learning!
Thank you for your comment! 3A means the Through-Beam Photoelectric sensors have a longer detection range in comparison to the Diffused Photoelectric sensors, which have a shorter detection range denoted by A. Happy learning!
Hi Rahman, Thanks for your comment! We currently only provide our course videos in English, you are always able to turn on the English subtitles as that might make it a bit easier for you. Our apologies for any inconvenience! Happy learning!
Here is one example: www.ifm.com/us/en/product/E21268. There are many others. Just search the web for "High Temperature Retroreflective" and you will get results from companies like IFM, Banner Engineering, VPEI, and other reputable automation companies.
