Product Description
A self-contained multi func-
tion diffuse ultrasonic sensor
with a sensing range of 25
to 200 mm. 1 switching out-
put - easily set up for NO or
NC switching modes and
adjusted by teach-in - makes
it ideal for level control tasks
in a wide variety of appli-
cations. A Stainless steel
housing provides the per-
fect packaging for the sofis-
ticated microprocessor con-
trolled and digitally filtered
sensor electronics. Excellent
EMC performance and pre-
cision are typical features
of this sensor based on true
distance measurement.

Teach in of output
All these functions may be programmed/taught by means
of the Teach-in input (pin 2) present in the connector. Each
mode has a unique indication using the Echo, P1 and P2
LEDs. The programming/Teach-In procedure is shown in the
following flow diagram:
Teach-In for
8 sec
Normal function:
The Echo LED is ON when an echo is received (alignment
LED). P1 LED is indicating status of the switching output.

Teach-in procedure
Normal switching function
The Teach-In function
When - in the following paragraphs, the term “Activate
Teach-In” is used, this means: make contact between the
Teach-in wire and GND wire once (ON-OFF) - could be done
with an externally mounted switch.
When - in the following paragraphs, the term “Hold Teach-
In” is used, this means: make contact between the Teach-in
wire and GND wire (ON) - could be done with an externally
mounted switch.
Teach-In of P1 (SP1 position)
Hold Teach-In for 8 seconds until SP and Echo LED’s start
flashing 2 times per second.
The sensor is now in teach mode for SP:
SP LED will now flash once per second and the Echo LED
returns to normal function (alignment LED).
The Teach-In function is now open for 1 minute to do the
programming of SP.
Place the target at the desired position.
Activate Teach-in: SP is now programmed.
Sensor returns to normal function with new value for
Switching output.
Switching output characteristics
can be selected during
teaching of the set point. If activating the Teach-In as the
LED is ON – the switching output will have NO characteris-
tics, if doing this as the LED is OFF, the switching output will
have NC characteristics.
Installation Hints
To avoid interference from inductive voltage/
current peaks, separate the prox. switch
power cables from any other power cables,
e.g. motor, contactor or solenoid cables
Relief of cable strain
Protection of the sensing face
Switch mounted on mobile carrier
Incorrect
Correct
The cable should not be pulled
A proximity switch should not serve as
mechanical stop
Any repetitive flexing of the
cable should be avoided
