Pepperl+Fuchs Blog

There are many great reasons to attend this year's Offshore Technology Conference (OTC). One is to experience the technology from Pepperl+Fuchs. From May 6 to 9 at OTC in Houston, Texas, Pepperl+Fuchs will be exhibiting its process automation solutions for the oil and gas industry. These leading sensing technologies, explosion protection products, and intrinsically safe mobile devices will be featured at booth 4261 in Hall A of the NRG Center. Conference attendees will have a chance to learn more about the following technologies:

Before we get into the advantages of radio frequency identification (RFID) over traditional barcode technology, let’s do a quick overview of both:

Barcodes are a series of machine-readable, parallel black bars that represent identification information. The information is encoded by varying the widths of the bars and the distances of the spaces between each bar. An optical barcode scanner then translates the information for further interpretation.


RFID products use unique radio waves to communicate information. Typical industrial RFID systems consist of an RFID reader (head), RFID interface (controller), and RFID tags (transponders).

There are few industrial automation technologies that are as versatile as RFID. Think of all the different kinds of industries—RFID is at work everywhere. We compiled ten of our favorite RFID applications that give you ideas for possible use cases and what benefits you can expect to gain by using industrial RFID.

1. RFID enhances Kanban systems
The modern “push” -based manufacturing concept with a Kanban system simplifies demand forecasting, as all necessary parts are refilled automatically. Small, flexible assembly units are formed. Parts bins are identified automatically and reliably using an RFID tag.

General questions about RFID tags

1. What is an RFID tag?

RFID tags carry information on a certain object or transport container. The size of an RFID tag can vary from the dimensions of a match head to a brick. While some tags are used simply as an attachable ID for an object, others carry a variety of different attributes relating to the object. These "identifiers” can be individualized according to the requirements of the specific process they are used in. Typically, an RFID tag (also called an “RFID transponder”) consists of an application-specific integrated circuit (ASIC) and either a small coil of wires or printed conductive paths that function as an antenna. These components are usually mounted to different kinds of protective packaging like plastic or silicon.
