In the meantime it is Ultrasonic sensor Technology has arrived in all industrial areas. Their USP characteristics are reliability, versatility, precision and robustness. Even under the harshest environmental conditions, ultrasonic sensors are insensitive to contamination because the sensors clean themselves through vibration. We present the new developments of the Pepperl + Fuchs Ultrasonic sensors.

Ultrasonic double sheet sensor for battery production
07.06.2022 | After the handling of large roles are from the foil webs suitable pieces are punched out for the batteries to be produced. Then these become battery cells put together. The feeding of the stamped material for the battery cell is monitored with ultrasonic double sheet sensors such as the UDC-18GS. You can tell whether there is one, two or no sheets in the detection area.
Ultrasonic sensor according to 3 PL-d for harsh environments and outdoors
27.11.2021/XNUMX/XNUMX | Pepperl+Fuchs offers with the Ultrasonic sensor USI safety a modern and certified sensor technology according to EN ISO 13849-1 Category 3 PL d for factory automation. In addition to access protection in security areas, the ultrasonic sensor is suitable for flexible solutions for autonomously operating units such as robots and Industrial trucks. The only one in the world Ultrasonic sensor system of this kind is very flexible.
The new Ultrasonic sensor protects people and objects from possible dangers and collisions. As a person-safe ultrasonic sensor, it joins the range of contactless effective protective devices for people and property.
The USI safety system guarantees reliable protection based on the design-related robustness the ultrasonic sensors. The separation of the actual sensor component from the evaluation unit enables an extremely compact design. The devices are easy to install even in very tight spaces.
The ultrasonic transducers of the USI safety system are in Degree of protection IP69K executed. This makes it suitable for outdoor applications and tolerates high-pressure cleaning. Their sound cone has an elliptical cross-section, which means they offer a particularly large detection area (range). The safety architecture is based on a consistent two-channel Electronics with fail-safe outputs and two microcontrollers monitoring each other. Up to two small, freely positionable ultrasonic sensors can be positioned, connected and parameterized geometrically independently of the electronics.
Protection already with an ultrasonic sensor unit
The protective function is already with only one sensor unit and thus without redundancy given. The sensors can be integrated into tight spaces and have a detection range of up to 2,5 m, in which moving and stationary objects of any colour, shape or surface are reliably reflected in an elliptical, three-dimensional field with sound waves. The function of the sensor is not affected by dirt, temperature, air flow or humidity.
The sensors are set up using a convenient Parameterization software. Two short-circuit and cross-circuit monitored OSSD safety outputs are available for each connected sensor unit. The entire detection area is taught in as a standard environment using the teach-in function. Disturbing vehicle contours are masked out. This increases operational safety.
"The USI is a perfect addition to our broad portfolio of ultrasonic sensors and at the same time expands our range in the strategic target sectors intralogistics and mobile machines with an intelligent and highly reliable safety application solution," comments Reiner Mueller, Head of Factory Automation at Pepperl + Fuchs.
Inductive sensor detects carbon for the first time in the world
The USI safety ultrasonic sensors are lined up in the existing one Safety portfolio from Pepperl + Fuchs. This currently includes inductive safety sensors, light grids and Optical Sensors, safe positioning systems, safety-related AS-Interface components and a large range of explosion-proof interface components.
The next level of ultrasonic sensors
21.12.2021/XNUMX/XNUMX | Ultrasonic sensor technology has developed from a niche product to a key technology in automation. During the second online summit, Pepperl and Fuchs will take a look at the current trends and future developments. Under the slogan Next level of ultrasonic technology presents Dr. Joachim Schullerer, Head of the Ultrasonic Sensors Innovation Unit at Pepperl + Fuchs SE, gave a keynote address on various aspects of ultrasonic technology, including state-of-the-art ultrasonic sensors and wireless M + O ultrasonic sensors.
Ultrasonic sensor detects splices in the packaging process
15.07.2019/XNUMX/XNUMX | For the Detection of splices In packaging, Pepperl + Fuchs has sensors in its portfolio with which a continuous packaging process can be reliably ensured. The ultrasonic sensors monitor the stack height regardless of color, shape or surface - and are maintenance-free. Teaching in the sensors is super easy.
In many packaging can be found protective or stabilizing plastic partsthat adapt to the contour of the product. This includes, for example, trays in chocolate boxes or presentation holders for cosmetic items. These molded parts are usually made by deep drawing. The film-like starting material is fed into the machine by rollers.
At the end of a used roll, the beginning of the new one becomes Roll attached with adhesive tape. This avoids time-consuming re-threading. However, the connecting adhesive strip must not get into the thermoforming unit. It is not necessarily suitable as a material for the molded part and would hinder the process due to undesired buildup in the thermoforming.
The connection between the film rolls must be reliably detected. That also applies to Splices within a role, because this can be made up of several lots. These transitions are cut out before deep drawing.
A second task in the packaging process is often the Stock of finished molded parts to be monitored at the feed to the packaging assembly. In both cases, the aim is to avoid any interruption in the process as far as possible.
Two tasks - one sensor
Ultrasonic sensors are ideally suited for both tasks. You can recognize the material of the roll goods and the finished molded parts regardless of their optical properties. The inevitable electrostatic charge on the plastic films is also of no concern to you.
The ultrasound Splice sensor UGB-18GM50-255 reliably detects the stuck area on the object with a response time of only 600 µs based on its soundproofing behavior, which differs from that of the roll material. The stack height of the stock of finished molded parts is measured with millimeter precision, for example, with the UB400-F77-E2-V31 ultrasonic sensor. Other designs can also be used for this application on objects with adhesive points. The user can choose between continuous monitoring and setting a limit value that triggers refilling.
Reflecting surfaces - no problem
The Films can be of any color or be printed in multiple colors. They are often transparent or have reflective surfaces. The molded parts have irregular contours, often with recesses or steep depressions.
Dispenser for anaerobic adhesives tested in long-term tests
None of these influencing factors play a role for ultrasound devices. The same sensor can be used for a wide range of materials can be used - even with highly diversified shapes. In the case of the ultrasonic sensors for detecting the splice, the very short reaction time of 600 µs enables the splice to be discharged quickly with the least possible waste of material. the Sensors allow dynamic teach-in while the machine is running. The sensor can be taught-in directly from the PLC via a digital output.
The splice sensor UGB-18GM50 has an extremely short response time, is compact and detects objects at a distance of 20 to 60 mm. the reflective mode UB400-F77, on the other hand, detects objects with a range of 25 to 400 mm and has a learning input. Both sensors are very compact.
