WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to
serious injury or death. This device does not include the self-checking redundant circuitry necessary
to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an
energized or de-energized sensor output condition.

Principles of Operation
Ultrasonic sensors emit one or multiple pulses of ultrasonic energy, which travel through the air at the speed of sound. A
portion of this energy reflects off the target and travels back to the sensor. The sensor measures the total time required
for the energy to reach the target and return to the sensor. The distance to the object is then calculated using the
following formula: D = ct ÷ 2
D = distance from the sensor to the target
c = speed of sound in air
t = transit time for the ultrasonic pulse
To improve accuracy, an ultrasonic sensor may average the results of several pulses before outputting a new value.
Temperature Effects
The speed of sound is dependent upon the composition, pressure and temperature of the gas in which it is traveling. For
most ultrasonic applications, the composition and pressure of the gas are relatively fixed, while the temperature may
fluctuate.
In air, the speed of sound varies with temperature according to the following approximation:

To order the 9 m cable models, add the suffix w/30 to the model number of a cabled sensor (for example, QT50UDB w/30). A
model with a QD connector requires a mating cable. Information about analog-output models is available on Banner Engineering
