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.
wenglor ultrasonic sensors are characterized by their ease of use and excellent technical properties.

They
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).
