Ask an Expert Industrial Sensors - Episode 11

Posted by John Appleson on Thu, Jul 23, 2015

This episode of Ask an Expert for industrial sensors examines and provides answers to interesting sensing questions we've received from customers just like you. We explore and answer these questions:

  1. How do I get a narrower sound cone on an F260 series ultrasonic sensor?
  2. Is AS-Interface "data decoupling" the same as "filter integrated"?
  3. Can I use a diffuse mode photoelectric sensor to detect marks on a steel rivet?
  4. What is the output stage used for on an inductive sensor?

Photoelectric Sensors: A Contrasting View

Posted by Patricia Stafford on Thu, Jul 09, 2015

What is a contrast sensor?

Contrast sensors have the ability to reliably distinguish between two different colors. They are also called print mark or registration mark sensors. These sensors are good for applications such as verifying the presence of a weld seam, confirming that a label has been placed on a package, and detecting registration marks. Basically, these sensors indicate whether a contrast between two taught-in colors is seen or not seen.

Photoelectric Sensors: 5 Things You Need to Know

Posted by Nick Ferguson on Thu, Jun 11, 2015

Photoelectric sensors are a great choice for packaging, material handling, automotive, and many other applications. They use a light emitter, a light receiver, and a lens for detection. Photoelectric sensors are often the go-to sensor, when an inductive sensor does not fit the application. They are incredibly useful for detecting a variety of objects, but it is important to be aware of their limitations.

Industry 4.0 Comes to Hannover Fair 2015

Posted by Patricia Stafford on Wed, Apr 01, 2015

The Internet of Things is an up-and-coming technology which is set to transform the way we live. Simply put, it allows machines to communicate directly with each other over the Internet. This connection between machines will lead to greater convenience and efficiency based on a more rapid exchange of information. Everyday examples might include a car telling a garage door when to open or close, a stove turning itself on to boil a pot of tea that will be ready for you when you come home from work, a timer setting thermostats, and your refrigerator letting you know when you’re running low on groceries.

Smaller Can Be Better with Fiber Optic Sensors

Posted by Tom Corbett on Fri, Jan 30, 2015

Fiber optic sensors sometimes get a bad reputation because of their small size or oddly shaped sensing tips. But, actually, it’s their size and shape that give them unique advantages over typical photoelectric sensors.
