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 x 20 mm, 100 x 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.

Setting the switching point
The ultrasonic sensor features a switching output with
a teachable switching point. The yellow LED indicates
whether the object is within the switching range of the
sensor.
One switching point is taught. This must be within the
detection range. In this operating mode the background
is suppressed.
Simple Teach-In
Place object at the end of the switching range
Pin 2/seal the white core against Ub for 2…7 s
ñ Return to normal operating mode after 17 s or more.
After a successful teach-in, the yellow LED flashes 3
times and the sensor runs automatically in normal oper-
ating mode.
LED response
In normal operating mode, the LED signals the switch-
ing state of the sensor.
