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” (e.g., QS18UNAQ8).
- For 4-pin Euro-style 150 mm (6") pigtail QD, add suffix “Q5” (e.g., QS18UNAQ5).
- For 4-pin integral Pico-style QD, add suffix “Q7” (e.g., QS18UNAQ7).
- For 4-pin Pico-style 150 mm (6") pigtail QD, add suffix “Q” (e.g., QS18UNAQ).
## **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 deenergized sensor output condition.

WORLD-BEAM QS18U Ultrasonic Sensors
## **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**
**==> picture [158 x 15] intentionally omitted <==**
**Cm/s** = speed of sound in meters per second
**TC** = temperature in °C
**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.
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.

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**
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** ."

## **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.

Teaching the same limit twice automatically centers a 20 mm window on the taught position.
## **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 program.

## **Normally Open/Normally Closed Operation Select**
The sensor can be configured for either normally open or normally closed operation via the remote teach wire (white). A series of three pulses on the line will toggle between normally open (NO) and normally closed (NC) operation. Normally open is defined as the output energizing when the target is present. Normally closed is defined as the output energizing when the target is absent. (See _Figure 3. Teaching independent minimum and maximum limits_ on page 4 and _Figure 4. Using the Auto-Window feature for programming each output_ on page 5.)
