Wenglor ultrasonic sensors are almost completely insensitive to interfering factors (such as extraneous light, dust, smoke, mist, vapor, lint, oily air, etc.). They are best suited for the detection of transparent and dark objects, reflective surfaces, shiny objects and of bulk materials and liquids. Ultrasonic sensors allow for the reliable detection and measurement of objects, independent of their material, color, transparency and texture.They are characterized by their ease of use and excellent technical properties.

The senors send pulsed ultrasonic waves of a certain frequency and determine the objects distance from the duration of the ultrasound that it reflects. The output switches if the specified switching point is reached. The measured value is output as a voltage value (0...10 V/4...20 mA) or in digital form (IO-Link).
