Frequently Asked Questions on RFID (Part 3)

Posted by Klaus Schmitt on Wed, Feb 24, 2016

General questions about RFID frequencies

1. Which frequencies does RFID use?

To enable noncontact data exchange via an RFID system, radio waves are used for communication. Depending on the application requirements, RFID systems utilize different frequency ranges. As a general principle, most RFID systems use the so-called ISM bands (Industrial, Scientific, and Medical Band) in order to avoid cross-talk of radio systems and ensure reliable data information exchange. Commonly, passive RFID systems use either low frequency (LF), high frequency (HF), or ultra-high frequency (UHF).

General questions about RFID readers

1. What is an RFID reader?

An RFID reader is an active device that uses radio frequency to read information contactless from a data carrier like an RFID tag. Most of the readers are also able to function as write units. Typically, RFID reading devices contain a microprocessor or digital signal processor.

Frequently Asked Questions on RFID (Part 1)

Posted by Klaus Schmitt on Tue, Feb 16, 2016

General questions about RFID technology

1. What is RFID?

RFID stands for “ radio frequency identification” and refers to technologies that use radio waves to identify objects or people automatically. RFID makes use of the so-called “air interface,” transmitting electromagnetic waves through the air. Typically, a serial number or other product- /object-related information (“identifier”) is stored on a microchip. This chip is attached to an antenna that enables the chip to transfer the information needed for identification to a reading device. The combination of antenna and chip is called an “ RFID tag” or “ RFID transponder.”

Industrial UHF RFID Easily Integrates into Studio 5000 Logix Designer

Posted by Tim Cicerchi on Fri, Oct 23, 2015

Industrial RFID systems are not that difficult to use. If you use a UHF RFID system, however, the complexity is increased.  The reason is because of the overall large amount of possible data sets that can be retrieved and sent to the user.  Below is a video on how to integrate our UHF RFID systems into an Allen-Bradley PLC using Studio 5000®.

Boosting Productivity with the Help of Laser Barcode Scanners

Posted by Tim Cicerchi on Thu, Jun 25, 2015

Laser barcode scanners have been used in material handling applications for decades.  It is an integral part of routing boxes down a conveyor line.  The production of products such as liquid soaps, lotions, and shampoo will use barcode readers also.  They are used in two places.  First, to read the pallets of raw material bottles at the beginning of the production line, then secondly, at the end of the line after barcodes are applied to the bottles.  The barcode readers have to read at very high read rates of over 200 bottles per minute.

Ask an Expert Industrial Sensors - Episode 10

Posted by John Appleson on Fri, Jun 19, 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. What lengths of WCS absolute linear encoder system rails are available, and how do they connect?
  2. We are designing a cargo door locking system that has to be tamperproof. Would RFID technology work for this application?
  3. I was planning to use photoelectric sensors for people detection in a specific area. Which photoeye should I use?
  4. How do the wires connect in cable connector 42308C?
  5. How do I incorporate an AS-Interface network into an Allen-Bradley PLC?

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.

Industrial RFID: UHF Parameters Revealed

Posted by Tim Cicerchi on Wed, Jan 21, 2015

A UHF RFID system is a bit more more complicated to configure and set up than an inductive short-range RFID system.  The Pepperl+Fuchs IUH-F190-V1-FR2-02 read head is a UHF head that makes many of the tough decisions for you.  You don’t need to know about anti-collision algorithms, sessions, inventory queries, or select flags.  We use simple concepts and a reduced parameter list to make it easy for anyone to set up an RFID system.
