Ultrasonic Product Selection Guide
OPERATION PRINCIPLE
Ultrasonic sensors have an acoustic transducer which is vibrating at
ultrasonic frequencies. The pulses are emitted in a cone-shaped
beam and aimed at a target object. Pulses reflected by the target to
the sensor are detected as echoes. The device measures the time
delay between each emitted and echo pulse to accurately deter-
mine the sensor-to-target distance.

Input
All materials sensing Ultrasonic Position Sensors solve the toughest
sensing problems and detect targets made of virtually any material,
regardless of color. They detect clear, transparent and shiny targets
as easily as dark and opaque materials. This ability allows ultrasonic
sensors to detect materials ranging from clear glass bottles to black
rubber tires. In a shrink wrapping operation, for instance, the sensor
can accurately and repeatedly detect the wrapping material regard-
less of how shiny or clear it may be. Ultrasonic sensors also work
well in tough environments — fumes, dust, noisy.
