Ultrasonic sensors are most commonly used in the diffuse mode. A single ultrasonic transducer is used as both emitter and receiver and is typically contained in the same housing as the evaluation electronics.

To reliably detect difficult objects, the majority of our diffuse mode sensors can be converted to retroreflective operation via software parameterization. Some ultrasonic sensors are supplied as retroreflective sensors from the outset.

Ultrasonic thru-beam sensors feature an extremely powerful acoustic beam. They offer a large detection range within compact housing dimensions. Unlike diffuse and retroreflective models, these sensors do not continuously switch between transmission and reception modes or wait for an echo signal to arrive. Thus, their response time is considerably faster, resulting in very high switching frequencies.

Double sheet sensors are ultrasonic thru-beam sensors that have been optimized specifically for sheet feed applications, including double sheet detection, label counting, and splice detection.

Double sheet and double material sensors distinguish between empty gaps, one, and two layers of material, including paper, metals, wooden boards, and glass panes.

When performing label detection tasks, the sensors can distinguish between the label backing and the base material.

Compatible accessories offer enormous potential for cost savings. Not only do you save a great deal of time and effort when installing the sensors, but also when servicing them. If products are used in harsh ambient conditions, appropriate Pepperl+Fuchs accessories can be used to extend the service life of the sensors.

The USi-safety ultrasonic sensor system is breaking new ground for safety applications—whether in challenging, dusty environments or in outdoor areas. Machines and vehicles can be reliably protected using state-of-the-art ultrasonic technology and all of the advantages this brings.
