2.1 Use for Intended Purpose
This sensor is used for object detection and distance determination.
Ultrasonic sensors emit pulsed ultrasonic waves at a certain frequency using air as a transmitting medium.
The sensors evaluate the transit time of the ultrasound reflected from the object. Parameters can be taught
into the sensors using the teach-in key, via an input or via IO-Link. The output is switched when the preselect-
ed switching point is reached. Two independent switching outputs can be set up. Furthermore, the measured
value can be read out via IO-Link 1.1. In addition to reflex mode, two sensors can also be used in through-
beam mode.
The product may only be used in the specified ambient conditions (see technical data on the product detail
page at www.wenglor.com). The guidelines, safety data and approvals specified in the technical data must
also be taken into account.
This product can be used for object detection or distance measurement in the following industries:
• Special machinery manufacturing
• Heavy machinery manufacturing
• Logistics
• Automotive industry
• Packaging industry
• Pharmaceuticals industry
• Clothing industry
• Plastics industry
• Woodworking industry
• Consumer goods industry
• Paper industry
• Electronics industry
• Glass industry

The warm-up phase lasts roughly 30 minutes. At the beginning of the warm-up phase, linearity deviation and
reproducibility may deviate from the specified values. During the course of the warm-up phase, values im-
prove as an exponential function until the values in the technical data are reached. The switch-on drift during
this time is shown in the following diagram.

5.1 Installation
• Protect the product from contamination during installation.
• Observe all applicable electrical and mechanical regulations, standards, and safety rules.
• Protect the product against mechanical influences.
• Make sure that the sensor is mounted in a mechanically secure fashion.
• If the object has smooth surfaces, the angle between the axis of the sound waves and the surface of the
object
should be 90° ±3°. The angle can be considerably larger in the case of rough object surfaces.
• The sensor’s sensing face must remain unobstructed.
NOTE!
Observe the blind spot.
In the area between the sensor’s active surface and the beginning of its working range,
correct functioning of the sensor is not assured. No objects may be located in this area.

Warning Warning signal • Reduce the distance between the sensor and the object
• Adjust the angle to the object
Undervoltage • Increase the voltage supply to at least 18 V DC
Error
No signal
• Adjust sensor object distance
• Minimize environmental influences (air circulation, ultrasonic sources)
• Check installation
Object too close • Increase sensor object distance
Object too far • Decrease sensor object distance
Short circuit • Check the electrical wiring and eliminate the short circuit
Over-temperature • Disconnect the sensor from the supply voltage and allow it to cool
Device error • Disconnect the sensor from the supply voltage and restart it
• Replace the sensor
Via IO-Link, it is possible to identify the respective causes precisely by means of condition monitoring. Further
diagnosis functions and status messages are also possible. See section “8.2 Condition Monitoring/Process
Data” on page 33.
