On Friday, August 25th, Hurricane Harvey hit the South Texas coast. Consequently, the storm front struck our new manufacturing and warehouse building in Katy, Texas. High wind from a hurricane tornado damaged our roof structure, pulling air handling units from the roof and allowing water to enter the building.
NAMUR sensors solve the same applications that standard inductive and capacitive sensors or rotary encoders would—but they are safe to use in hazardous areas. NAMUR output sensors are ideal for applications where the presence of a volatile gas, vapor, dust, or fiber creates a possible hazard.
To prevent an explosion in hazardous areas, these sensors protect the circuit by operating at 8.2 V and less than 5 mA. These levels prevent the device from storing sufficient energy to initiate an explosion. NAMUR sensors are connected to an isolating amplifier, which limits the current and voltage to the sensor and amplifies the signal upon return.
Our UC-F77 ultrasonic sensor is easy to set up and program using PACTware Connection Wizard software. In the video below, I'll show you how to configure the sensor and also demonstrate some of its unique features. One of my favorite new features is that it solves a common problem for ultrasonic sensors: It allows suppression of echoes from false targets.

We’ve all experienced the frustration of trying to make a phone call in a noisy environment—at a sporting event, concert, restaurant, or bar. You struggle to hear what the person on the other end is saying and find yourself yelling “what!?” or “can you repeat that!?” into the phone.
What do you need to get started?
- You will need the AS-Interface Toolkit for Rockwell Automation PLCs—it's a Zip file you can download from our website.
- This toolkit is intended to help a PLC programmer by providing ALL the necessary tools for integrating AS-Interface into a Rockwell Automation PLC.
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).
AS-Interface gateways control the AS-Interface system and make the process data available to all higher-level networks of the PLC in a defined configuration. Pepperl+Fuchs offers AS-Interface gateways for all standard buses such as EtherNet/IP, PROFINET, PROFIBUS, DeviceNet and CC-Link. When considering EtherNet/IP or MODBUS/TCP gateways for AS-Interface networks, keep these benefits in mind:
Ultrasonic sensors are non-contact devices used for object detection or level measurement. They operate on the principle of sound traveling through a medium, where a transducer emits a sound wave at a specific frequency. Based on the time it takes the reflected sound pulse to reach the transducer, the sensor’s internal logic determines if the object is within the nominal sensing range and generates an output signal.

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:
- What load does a proximity switch need to sense for bench testing?
- Does the SJ5-N inductive slot sensor need an intrinsic safety barrier?
- Should I use a fiber optic sensor for injection molded parts detection?
- Are the components in an AS-Interface circuit board module epoxy encapsulated or sealed?
- Do you have a handheld solution to identify nonworking RFID tags?
Automated guided vehicles (AGVs) are used to move product throughout the factory or warehouse floor. Speed and precision are key when moving materials— if you've seen AGVs zipping around in a warehouse, you want to ensure that they stay on track and that they go exactly where they need to, with materials and AGV intact.
The video below discusses the key features and general applications for our PGV absolute positioning system for automatic guided vehicles. The PGV follows Data Matrix codes or colored lines with sub-millimeter precision and is ideal for guidance of AGVs.
From control codes to initiate starts, stops, and turns, to the user-friendly software Vision Configurator, the PGV is packed with the tools you need for any AGV application.
