Photoswitches, proximity sensors, and feedback devices are all used to detect objects or information. They are useful in industrial and manufacturing environments to sense product or personnel in the line of machinery or equipment. This module discusses the operation of the different types of each of these.

At the end of this module, you will be able to:

  • Describe the purpose of a photoswitch and its general operating principles
  • Differentiate between the five basic types of photoswitches (retroreflective, thru-beam, polarized, diffuse, and convergent beam)
  • Match the three basic types of proximity sensors (inductive, capacitive, and ultrasonic) with their principles of operation
  • Describe the purpose of a proximity sensor
  • Explain the operation of three feedback devices (incremental encoders, absolute encoders, and Hall effect sensors)
  • Describe the purpose of a feedback device

The following key questions are answered in this module:

What are photoswitches, proximity sensors, and feedback devices used for?
Photoswitches, proximity sensors, and feedback devices are all used to detect objects or information. They are useful in industrial and manufacturing environments to sense product or personnel in the line of machinery or equipment.

What is a photoswitch?
Photoswitches are electrically powered sensors that detect light. They are typically used to sense the presence or absence of an object.

What are some common types of photoswitches?
Common types of photoswitches include retroflective, thru-beam, polarized, diffuse, and convergent beam.

What are proximity sensors?
Proximity sensors are used to detect the presence of machinery or material in situations where it is impossible or impractical to touch what is being detected.

What are some common types of proximity sensors?
Common types of proximity sensors include inductive sensors, capacitive sensors, and ultrasonic sensors.

What are feedback devices?
Feedback devices are used to gather and transmit information, such as motor speed, back to a controller.

What are some common types of feedback devices?
Common types of feedback devices include incremental encoders, absolute encoders, and Hall effect encoders.

Below is a transcript of the video sample provided for this module:

Unlike the incremental encoder, the absolute encoder obtains position information. The absolute encoder has multiple rings etched on the disk. The first ring has one light segment and one dark segment, each successive ring has doubled the number of segments from the previous ring. The number of rings determines the number of bits of resolution of the encoder. This can be used to determine the number of steps that an encoder can detect. The output of the device is a binary number. As the disk turns, the binary number increases. Absolute encoders typically use a binary code called the gray code, in which only one bit changes as the sequence increases. The binary number or gray code number can be used to determine shaft position.

Ask a Question

Sorry, we're missing some information

How do I log in to watch a video that I have already paid for?

Easy! Moments after you purchase your pay-per-view (PPV) course, you'll receive an email with login details. Just click the link and log in with your user name and password and you're on your way!

I would like to have some of my employees take 5 of your driving related courses, how can i set this up?

We're in the process of making bulk purchases and purchases for multiple users easier. But for now, you can order multiple courses and just let us know who you'd like to assign courses to. With an email for each user, we can set up their training plans and make sure everyone gets the eLearning assignments they need.

How can I get your paper-making courses for free?

Well, we can't blame you for asking... And while we're a for-profit company, there are situations with students and certain educational organizations where we can help out with a selection of eLearning. However, our online courses are extremely economical. And our paper industry courses are in very high demand. So, without knowing more about your situation, we think you'll get loads of value from the $39 you'll spend on any of our premium courses.

Do you have eLearning in Portuguese?

Yes, we do! And in addition to primary English narration, we produce many courses in a growing number of languages, including Spanish, Chinese, Dutch, German, Italian, Japanese, Korean, Polish, Russian, Tamil, and Thai.

I'm unemployed, but I really like your eLearning. Do I get a certificate when I complete a course?

Yes! All of our courses allow you to print a completion certficate upon successfully passing the integrated test at the end of eLearning. In the future, we'll have badges for you to use in your LinkedIn profiles.
