Pepperl and Fuchs manufactures Ultra Sonic switches and sensors.
Pepperl and Fuchs Ultrasonic sensors present the ideal solution for non-contact position and distance measurement in all industrial areas where environmental conditions such as dust, smoke or steam may affect the sensors. Objects consisting of a variety of materials can be detected to within millimeters regardless of color or shape.
The ultrasonic sensor produces a data carrier utilizing very high frequencies that are outside the human’s audible range. The time it takes for that ultrasonic wave to pass between the sensor and the object is the value for the distance or the position. Ultrasonic sensors have proven their reliability and precision in many industries, including lumber and furniture, construction materials and equipment, farming equipment and in level control applications.
Pepperl+Fuchs’ ultrasonic sensors currently encompass twelve series of mechanical designs for through-beam, direct detection and retro-reflective operation. Customer and application specific custom solutions underscore our technological competence in this area of sensors.
Product features:
Devices with TEACH-IN functionality for fast and simple installation
ULTRA 3000 software for improved adaptation of sensors to applications
Adjustable sensitivity to the sound beam width for optimized adjustment of the sensor characteristics according to the application
Temperature compensation - compensates for sound velocity due to varying air temperatures
Synchronization input to prevent cross-talk interference when sensors are mounted within close proximity of each other
Sensors with digital and/ or analog outputs

A Pepperl and Fuchs ultrasonic through-beam sensor consists of a transmitter and a receiver that are installed so they are facing each other.
The working principle of ultrasonic through-beam sensors is based on the transmission of a sound wave from the transmitter to the receiver being interrupted by the object that is being detected. The transmitter generates an ultrasonic signal that is evaluated by the receiver. When the ultrasonic beam is damped or interrupted by the object being detected, the receiver output switches states.
No electrical connections are required between transmitter and receiver and the functionality of the ultrasonic through-beam sensors is also independent of the installation location. To prevent dirt particles from accumulating, however, we recommend placing the transmitter facing up when components are mounted vertically.
Product Features:
Long detection ranges since the ultrasonic beam only travels in one direction
Short response times
Less subject to faults and thus very suitable for applications in difficult conditions
Additional installation expense since both units have to be wired.

In the direct detection system,
The transmitter and receiver are in the same housing in this type of ultrasonic sensor. A single ultrasonic transducer is switched cyclically between transmit and receive mode. The object itself acts as the sound reflector.
Product features:
The sensing range depends on the reflectivity of the object, including the surface properties and the angle of incidence. These effects can be compensated for (within limits) by a sensitivity adjustment
Low installation expense, since the sensor consists of just one unit
Sensitive to changes in the reflective properties of the target
Dual transducer system
Placing separate transducers for transmitting and receiving next to each other in the same housing significantly reduces the blind range since there is no need to wait for the transmitter signal to decay.
Ultrasonic sensors with discrete outputs and analog outputs are available as direct detection sensors. All direct detection sensors that support the "Window mode" output function can also be used as retro-reflective sensors (see retro-reflective sensors).
