Datasheet

Long-range ultrasonic sensors with TEACH-mode programming

• Fast, easy-to-use TEACH-Mode programming; no potentiometer adjustments

• Scalable output automatically distributes the output signal over the width of the

programmed sensing window

• Minimum and Maximum window limits can be adjusted independently

• Selectable 0 to 10 V dc or 4 to 20 mA output, selected via DIP switch

• Access to bank of 8 DIP switches through sealed cover for superior user

functionality

• Rugged encapsulated design for harsh environments

• Unique housing design allows for multiple mounting configurations

• Choose models with integral 2 m (6.5 ft) or 9 m (30 ft), or with Mini-style or

Euro-style quick-disconnect fitting

• Wide operating range of –20 °C to 70 °C (–4 °F to 158 °F)

• Temperature compensation

• Programmable for either positive or negative output slope

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:

Information about discrete-output models is available on Banner’s website: www.bannerengineering.com.

To order the 9 m cable models, add the suffix “w/30” to the model number of a cabled sensor (e.g., QT50ULB w/30). Models with

a QD connector require a mating cable.
