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?

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.

Diffuse Use – Ultrasonic Diffuse Mode Sensors Are Everywhere

Posted by Patricia Stafford on Thu, Jun 04, 2015

What are ultrasonic diffuse mode sensors?

Diffuse mode is the most common way to operate an ultrasonic sensor. In this mode, the transducer is contained in the same housing as the evaluation electronics and acts as both an emitter and receiver. Because of this design, this type of ultrasonic sensor works by continuously switching between transmission and reception modes and waiting for echo signals.

Laser Sensors that Measure the Distance!

Posted by Amanda Blakeman on Thu, May 07, 2015

You read that right.  Now with Pulse Ranging Technology (PRT), laser sensors can determine the distance to an object by emitting short, high-energy light pulses over a given distance.

Using AS-Interface to Monitor Valve Position

Posted by David Fink on Thu, Apr 30, 2015

An automated valve assembly typically consists of a rotary travel process valve, a pneumatic actuator, a solenoid valve and in some cases, a bracket to mount the valve to the actuator.  The operation of the valve assembly is accomplished by energizing and de-energizing the solenoid. But how can the operator in the control room tell if the valve is open or closed?

Remote Monitoring via KVM Extenders

Posted by Lou Szabo on Thu, Apr 23, 2015

KVM Extender Selection Criteria

Industrial keyboards, video monitors, and/or mice are usually located within 6 feet or 2 meters of the source PC or thin client. However, there are times when you need to mount an industrial display farther away from the source signal—sometimes in a different building or type of location, such as outdoors, on the process floor, and/or in a hazardous location.

Ask an Expert Industrial Sensors - Episode 8

Posted by John Appleson on Wed, Apr 15, 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. Magnetic sensor MB60-12GM50-E2: What is the performance of this sensor like if the sensing surface is less than 10 mm away from the sensor?

2. How does the magnetic field sensor 41FY1 work? Is it a two-part magnetic sensor?

3. What is the required target size for the inductive sensor NJ5-18GM-N-5M? Will a 1/8 in. wide keyway that is .03 in. deep on a 4 in. diameter shaft work?

4. I'm trying to connect an NBB5-12GM50-E0-V1 inductive sensor to a PLC, but I am unable to make the two work together correctly!

5. Do you have cable connectors? What about for specialty cable types?
