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 60947-5-7, 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 limit values
The ultrasonic sensor has an analog output
with teachable measuring range. Teaching is
implemented via the teach adapter. The green
and yellow LEDs indicate whether the sensor
has detected the object.

Teach
Connect the TX1-Q20L60 teach adapter
between the sensor and connection cable
• Position object for remote limit value
• Press the button against Ub for 2 - 7
seconds
• Position object for close limit value
• Press the button against Ub for 8 - 11
seconds
Optional: Inversion of analog output
• Press the button for 12 - 17 seconds

Successful teaching is displayed with a
fast flashing LED. Thereafter, the sensor
automatically runs in normal operating mode.
Unsuccessful teaching is indicated by the LED
flashing alternately green and yellow.
In normal operation, the two LEDs indicate the
status of the sensor.
• Green: Object within the detection range, but
not in the measuring range
• Yellow: Object is within the measuring range
• Off: Object outside the detection range or
signal loss
