WORLD-BEAM QS18U Ultrasonic Sensors

Datasheet

Miniature Ultrasonic Sensors with TEACH-Mode Programming

•

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

Ultra-compact housing

One discrete output: NPN or PNP, depending on model

Two bi-colored status LEDs

Rugged encapsulated version for harsh environments

Choose 2 meter or 9 meter unterminated cable, 4-pin Euro-style or 4-pin Pico-

style QD connectors (either integral or with 150 mm pigtail)

•

Wide operating range of –20 °C to 60 °C (–13 °F to 140 °F)

Temperature compensation

Configurable for normally open or normally closed operation

Fast response time (15 milliseconds)

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.

Only standard 2 m (6.5 ft) cable models are listed. For 9 m (30 ft) shielded cable, add suffix “W/30” to the model number

(e.g., QS18UNA W/30). A model with a QD connector requires a mating cordset. For QD models:

•

For 4-pin integral Euro-style QD, add suffix “Q8” (for example, QS18UNAQ8).

For 4-pin Euro-style 150 mm (6 in) pigtail QD, add suffix “Q5” (for example, QS18UNAQ5).

For 4-pin integral Pico-style QD, add suffix “Q7” (for example, QS18UNAQ7).

For 4-pin Pico-style 150 mm (6 in) pigtail QD, add suffix “Q” (for example, QS18UNAQ).

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.
