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.
Every sensing technology has its own set of unique capabilities that allow it to perform reliably in certain areas. In dirty environments, a photoelectric sensor’s light beam may fail to return to the receiver due to a covered lens or reflector. However, ultrasonic sensors thrive in dirty and dusty environments, since sound waves are unaffected by dust particles floating in the air or adhering to the sensing face. Industries that commonly use ultrasonic sensors include agriculture, food and beverage, and packaging. The following key attributes will help you select the right ultrasonic sensor for your application.

Process automation plants using industrial HMI often place the equipment in remote locations in the field, away from the process control room or maintenance stations. For busy plant personnel, it's much easier to be able to configure these remote monitors from a centralized location or even off-site remote location. In addition, maintenance and technical support for the daily HMI operators can now be done remotely without needing to physically stand in front of the screen, which is often difficult and time-consuming (pharmaceutical clean rooms, large refineries for example.)
AS-Interface gateways are the core of the wiring system. They serve as the link between the sensor/actuator level of AS-Interface and the upper-level bus systems where PLCs (programmable logic controllers), PCs or other field bus systems reside.
When installing a purged control panel or industrial HMI in a hazardous location, power supplied to the control panel must be regulated so that components are not energized before the panel is protected by a purge cycle.
- Do you have non-incendive inductive proximity sensors?
- Diffuse mode photoelectric sensors - what are the adjustment ranges?
- Do you have a steel-sensing sensor that can withstand temperature extremes, shock, and vibration?
- Can the inductive sensor NJ8-18GK-SN be ordered with terminal connections instead of leads?
What Is the Difference Between Zone 1 and Division 1?
A Zone 1 / Div. 1 industrial monitor must meet the requirements necessary for operating in the presence of ignitable concentrations of gases, vapors, or dusts that are likely to exist, either continuously or intermittently, under normal conditions. That said, the certification requirements vary according to where you will be using your equipment.

As an industry leader, Hilmot is constantly working to improve its innovative technologies in material handling applications. Hilmot turned to Pepperl+Fuchs, a pioneer in industrial sensors and factory automation systems. Leveraging the advantages of AS-Interface, Pepperl+Fuchs developed a motor control module compatible with Hilmot's motorized drive roller (MDR) applications—the H-20 line of MDR systems.
