What is a 2-D laser scanner?
A 2-D laser scanner consists of a light beam that’s rotated or fanned around a circular path in order to detect anything that is in the plane of the light beam. The light beam emitted will measure both the distance and the angle to the given object in the plane of view.
Most people are amazed that the dust from a number of everyday materials can become explosive under the right conditions: grains, sugar, metals, plastics, coal, coffee creamer, corn – just to name a few.
Because of this potential for explosion, dust hazards exist in many different industries:

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. Replacing a diffuse mode photoelectric sensor that is tied to an AS-Interface module.
2. Do you have MTTF data for the NMB1.5-8GM35-E0-FE inductive sensor?
3. Can diffuse mode sensors be used to detect metal drums in a hazardous area?
4. How to choose the correct power supply for RFID control interface unit IC-KP-B17-AIDA1?
5. Where on your website can I download AS-Interface system wiring guidelines and connection diagrams?
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.
The award marks the 13th consecutive year for the top purge award
In the categories of Purge and Intrinsic Safety, Pepperl+Fuchs has steadfastly dominated opinion polls by readers of two of the industry’s leading publications. This year, Pepperl+Fuchs once again was voted best provider of intrinsic safety and industrial enclosure purge systems by Control magazine in its 2016 Readers’ Choice survey.
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.
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.
