Wiring diagram
Functional principle
Ultrasonic sensors capture a multitude of
objects contactlessly and wear-free with
ultrasonic waves. It does not matter whether
the object is transparent or opaque, metallic
or non-metallic, firm, liquid or powdery. Even
environmental conditions such as spray, dust
or rain hardly affect their function.
The sonic cone diagram indicates the
detection range of the sensor. In accordance
with standard EN 60947-5-2, quadratic targets
in a range of sizes (20×20 mm, 100×100
mm) and a round rod with a diameter of
27mm are used.
Important: The detection ranges for other
targets may differ from those for standard
targets due to the different reflection
properties and geometries.

Mounting instructions
Mounting instructions/Description
Setting the switchpoint
The ultrasonic sensor features a switching
output with a teachable switching point. The
green and yellow LEDs indicate whether the
sensor has detected the object.

One switching point is taught. This must be
within the detection range. In this operating
mode the background is suppressed.

Teach
• Connect the teach adaptor between the
sensor and connection cable
• Position the object at the beginning of the
protection area
• Press the button for 2 - 7 sec against Ub
•Place object at the end of the switching range
• Press the button against Ub for 8 - 11
seconds

After a successful teach-in, the green
LED flashes at 2Hz and the sensor runs
automatically in normal mode.

LED response
In standard operating mode, the two LEDs
indicate the switching state of the sensor.
• Green: Object within the detection range but
not in switching range
• Yellow: Object is within the switching range
• Off: Object is outside the detection range or
signal loss
