A device failure or malfunction can cause either an energized (on) or de-energized (off) output condition. Models Models Sensing Range QS18UNA QS18UPA QS18UNAE TEACH Option Cable Integral push button or remote TEACH (IP67, NEMA 6P) 50 mm to 500 mm (2 in to 20 in) Remote TEACH (epoxy-encapsulated, IP68, NEMA 6P) QS18UPAE Supply Voltage Output NPN 4-wire, 2 m (6.5 ft) cable with shield PNP 12 V DC to 30 V DC NPN PNP 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: • To order the 4-pin integral M12 QD model, add the suffix Q8 (for example, QS18UNAQ8). • To order the 150 mm (6 in) cable with a 4-pin M12 QD model, add the suffix Q5 (for example, QS18UNAQ5). • To order the 4-pin integral M8 QD model, add the suffix Q7 (for example, QS18UNAQ7). • To order the 150 mm (6 in) cable with a 4-pin M8 QD model, add the 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. 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: In metric units: Cm/s = 20 √273 + TC Cm/s = speed of sound in meters per second TC = temperature in °C In English units: Cft/s = 49 √460 + TF Cft/s = speed of sound in feet per second TF = temperature in °F Temperature Compensation Changes in air temperature affect the speed of sound, which in turn affects the distance reading measured by the sensor. An increase in air temperature shifts both sensing window limits closer to the sensor. Conversely, a decrease in air temperature shifts both limits farther away from the sensor. This shift is approximately 3.5% of the limit distance for a 20° C change in temperature. Original Document 119287 Rev. K 28 July 2021 119287 WORLD-BEAM QS18U Ultrasonic Sensors The QS18U series ultrasonic sensors are temperature compensated This reduces the error due to temperature by about 90%. The sensor will maintain its window limits to within 1.8% over the -20° to +60° C (−4° to +140° F) range. Note: • • • Exposure to direct sunlight can affect the sensor’s ability to accurately compensate for changes in temperature. If the sensor is measuring across a temperature gradient, the compensation will be less effective. The temperature warmup drift upon power-up is less than 7% of the sensing distance. After 5 minutes, the apparent switchpoint will be within 0.6% of the actual position. After 25 minutes, the sensing position will be stable. Sensor Programming Two TEACH methods may be used to program the sensor: • Teach individual minimum and maximum limits, or • Use Auto-Window feature to center a sensing window around the taught position The sensor may be programmed either via its push button, or via a remote switch. Remote programming also may be used to disable the push button, preventing unauthorized personnel from adjusting the programming settings. To access this feature, connect the white wire of the sensor to 0V dc, with a remote programming switch between the sensor and the voltage. Figure 1. Sensor Features Green/Red Power/Signal Strength LED Yellow/Red TEACH/Output Indicator LED Push Button (IP67 models only) Programming is accomplished by following the sequence of input pulses (see programming procedures). The duration of each pulse (corresponding to a push button “click”), and the period between multiple pulses, are defined as “T: 0.04 seconds < T < 0.8 seconds." Figure 2.

ON Red (solid) In Teach Mode, waiting for first limit. ON Red (flashing) In Teach Mode, waiting for second limit. Teaching Minimum and Maximum Limits General Notes on Programming • The sensor returns to Run mode if the first TEACH condition is not registered within 120 seconds. • After the first limit is taught, the sensor remains in Program mode until the TEACH sequence is finished. • To exit Program mode without saving any changes, press and hold the programming push button for more than 2 seconds (before teaching the second limit). The sensor reverts to the last saved limits. 2 www.bannerengineering.com - Tel: + 1 888 373 6767 P/N 119287 Rev. K WORLD-BEAM QS18U Ultrasonic Sensors Figure 3.
