Only standard 2 m (6.5 ft) cable models are listed. For 4-Pin Euro-Style integral QD, add suffix “Q8” to the model number (for example, T30UXDAQ8). For 150 mm (6 in) PUR pigtail cable with 4-Pin threaded Euro-Style QD, add suffix “QPMA” to the model number (for example, T30UXDAQPMA). For 9 m (30 ft) cable, add suffix “W/30” to the model number (for example, T30UXDA W/30). A model with a QD connector requires a mating cable; see Quick-Disconnect Cables on page 11.

U-GAGE® T30UX Series with Discrete Output
Overview
The U-GAGE® T30UX is an easy-to-use ultrasonic sensor with extended range and built-in temperature compensation. Simple push button configuration provides flexibili­ty for a variety of applications.
Easy-to-see indicator LEDs communicate the status of the sensor. The Green “Pow­er” LED ON indicates that the sensor is in Run Mode (the sensor’s normal operating condition). The Red “Signal” LED indicates the target signal strength. The Amber “Output” LED indicates that the output is enabled and the sensor is receiving a signal within the window limits (depending on NO or NC). The Amber “Mode” LED indicates the currently selected mode.
Figure 1. Features
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:
C
= speed of sound in meters per second C
m/s
In English units:
= speed of sound in feet per second
ft/s
TC = temperature in °C TF = temperature in °F
Temperature Compensation
Changes in air temperature affect the speed of sound, which in turn affects the total time for the echo 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 T30UX 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 2.2% over the -40° to +70° C (−40° to +158° F) operating range of the sensor.
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.
Sensor Configuration
Two TEACH methods may be used to configure the sensor:
• Teach individual minimum and maximum limits, or
Rev. G
• Use Auto-Window feature to center a sensing window around the taught position.

U-GAGE® T30UX Series with Discrete Output
The sensor may be configured either via its push button, or via a remote switch. Remote configuration also may be used to disable the push button, preventing unauthorized personnel from adjusting the configuration settings. To access this feature, connect the white wire of the sensor to 0V dc, with a remote configuration switch between the sensor and the voltage.
Configuration is accomplished by following the sequence of input pulses. The duration of each pulse (corresponding to a push button “click”), and the period between multiple pulses, are as “T”: 0.04 seconds < T < 0.8 seconds
Remote line configuration requires a greater than 1 second pause between pulse sequences.
Mode Setup - Output Configuration
Sensors can be set up for either NPN (sinking) or PNP (sourcing). In addition, the user can select between Normally Open (N.O.) and Normally Closed (N.C.) 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 2. Teaching independent minimum and maximum limits on page
4).

General Notes on Teaching
• The sensor will return to RUN mode if the first TEACH condition is not registered within 120 seconds after the initial 2 second hold on the Discrete push button.
• To exit TEACH mode without saving any changes, press and hold the Discrete push button or remote line longer than 2 seconds (before teaching the second limit). The sensor will revert to the last saved limits.
• After the first limit is taught, the sensor will remain in TEACH mode until the TEACH sequence is finished or exited by a 2 second hold on the Discrete push button or remote line.

The sensor will revert to previously saved configuration and return to RUN mode if TEACH is inactive for 120 seconds after the initial 2 second hold on push button

General Notes
• Run Mode is the sensor’s normal operating condition
• The duration of each Pulse is defined as “T”: 0.04 < T < 0.8 s
• A Hold will exit TEACH MODE and return to Run Mode with previously saved changes. The duration of a Hold is: T > 2 s
• A Timeout will occur if a condition is not registered within 120 seconds, causing the sensor to return to Run Mode (during sensor configuration only)
• Sensor configuration user feedback shown on Green LED. See flowchart.
• The Red Signal LED will be ON whenever the target is in view.
