Photoelectric Sensor Wiring and Setup

[@kasondensofwa4184]

Absolutely loud and clear. Especially that I've been working on these sensors for some time now without fully understanding the configurations. Thank you so much realpars, kindly consider setting up a hands on training center in Zambia.

[@realpars]

Great to hear that! Happy learning, Kasonde. We appreciate your positive feedback.

Hi Ajikar, Thanks for your message! This would make for a great topic suggestion for future video courses, I will happily pass this on to our course developers. Thanks for sharing and happy learning!

Hi! I found this channel very informative and useful! I am R&D Chemist and there is a real need to me to be able to design and assemble an experimental equipment based on PLC. I have some experience in designing equipment based on relay logic, but I would like to work with analouge signal too. What program do you recommend for such a beginners? I saw your video made 6 years ago. Is it still actual now or there is a new software?

[@deniskalugin7984]

@@realpars thank you very much!

[@realpars]

The current revision of software used to program Siemens PLCs is TIA Portal (STEP7) v17. Anything that we have demonstrated in STEP7 can be done in TIA Portal in much the same manner. All of the concepts we show in our videos with regard to sensors is still valid and the programming techniques are still valid. The only thing that has changed is the look and feel of the programming software (to be more modern and user friendly!). I suggest the S7-1200 starter kit for new programmers and those who want a low-cost system to use for development and testing: marketplace.realpars.com/products/s7-1200-ktp400-basic-starter-kit-6av6651-7ka02-3aa4?_pos=5&_sid=e40114d93&_ss=r

I really love the informative videos of REALPARS, I wish if you would make a video about "How to connect outputs (motors) to a PLC C1212 AC/DC/RLY", in the same way of explaining this informative video. 💫Rise and shine REALPARS team! 💫😎

[@jjlopez8696]

Why my diffused sensor needs to be an angle to detect my oats?

[@realpars]

Thank you for your question! The material type and size in front of the diffused sensor can affect its performance. You may need to adjust the sensor and its sensitivity potentiometer to get it to work correctly. Here is a helpful link for your learning: www.keyence.com/products/ Happy learning!

Maximum distance cover

[@luizaugustorodrigues2461]

Hi, it's possible to extend the sensor wires? Imagine you have a proximity sensor (Diffused) and a part counter connected, the sensor has 1 meter cable and the counter is positionated 2 meters away from the sensor. How can we deal with this wires lenght problem?

[@realpars]

For DC wiring, extending the wires is usually not a problem, unless you extend them very long distances. Very often, local junction boxes are used at the device to provide convenient access for maintenance and replacement, with wiring to the control system provided from the junction box. This wiring run can be as long as it needs to be (provided it is not so long as to degrade the signal due to wire resistance).

[@jake90770]

I have a question can you explain the fuction of the black wire better said what happens in the black wire when the sensors are blocked i work with high performance garage doors and they use some level of monitoring on the photoeyes sensors Thanks very informative your videos!

[@realpars]

Thanks for your feedback, Jake! I will happily pass this on to our course developers, as a topic suggestion for possible future video courses.

[@zoltanfarkas1544]

Hi! I have a retroreflective sensor, which is starting a conveyor. Does it matter if the sensor is perpendicular or parallel with the conveyor?

[@realpars]

Hello Zoltan Farkas, Thank you for your question. It depends on the application and device you use. Not sure where in the world you are, but here is a link that might be useful to help you make your decision. www.ia.omron.com/support/guide/43/introduction.html Hope this helps!

[@chrishargett8694]

Hi. quick question. If there is a remote starter switch, simple on/off, can the black wire be introduced there instead of back at the starter coil? TIA!

[@realpars]

You want to make sure any start command, local, automatic (as with the photoelectric sensor), or remote switches power to the starter/contactor. So yes, you could design a circuit where the black wire is energized by the remote switch or the photoelectric sensor to pull in the contactor. Just make sure all devices are being powered from the same 24VDC circuit to avoid voltage problems.

[@mannyclemente7159]

Real pars, there are sensors that have 4 wire cables. Brown, blue, black and white, is the black wire usually the normally open switch? Or does it depend on the application?

[@realpars]

Typically, with wires in that combination, brown and blue supply power. Brown is positive (high potential) and blue is common (low potential). Black is typically the signal wire in a 3-wire configuration, but in a 4-wire configuration, you need to consult the drawing for the device.

[@brunorossitt7668]

This was a really simple and well-constructed video. Can the diffused sensor be set up, in the opposite way, so that it turns the motor on when an object is detected in front of the sensor and turns off when it has moved far enough so that it is no longer detected? Im trying to fill a small holding conveyor up with pouches evenly.

[@realpars]

Hello Bruno, Thank you for your question. Yes, it can, depending on the one you purchase for your application. Some come with four wires. As we mentioned in our video, two of the wires are for power, and if some of these sensors come in 4 wires, two for power and one wire for normally open N.O. or normally closed N.C. depending on your application on how you want it to sense, for example with the object present or not present. And some sensors have a selection switch you decide for it to work N.O. or N.C. but not both. Here is a link to an international company with all the types of sensors you can think of for your application, with data sheets and learning information. www.bannerengineering.com/in/en/products/sensors/photoelectric-sensors.html?pageNum=Infinity&#all Happy learning!

[@balogunsamson7148]

I love this for making it clear to me but my question is the sensor is mounted at the middle of the conveyor how can the conveyor take the product to the sensor when the work of the sensor is the start the conveyor

[@realpars]

Sensor placement is important and requires the engineer to understand what the sensor is being used for. A sensor can be used for counting, in which case the sensor should be placed where objects will need to pass and clear the sensor during normal operation. Sensors used to control a conveyor (on/off) are typically put in the middle of the conveyor so that they can both sense when objects are flowing normally and when a jam (collection of objects upstream of the sensor) occurs. Starting a conveyor at the start is normally done by an operator, and then sensors can be used to start/stop conveyor traffic to maximize throughput.

[@karaannis9658]

Thank you for the helpful video! I'm working on a process improvement project and was wondering if it would be possible to use these sensors to connect to an Andon light (instead of a conveyor motor) to turn on when a package is recognized by the sensor?

[@realpars]

Yes, that can be done. The main consideration is that you need to match the output signal from the sensor to the requirements of the Andon light. This includes both voltage and power requirements. It is possible that you will need to provide a solid state interposing relay to switch power to the light stack with the low-level output from the sensor wired the relay coil.
