Remarks
Switching behavior dependent on the infeed direction
Depending on the direction of movement of the label tape through the sensor,
the following switching behavior occurs at the outputs:
Direction of movement
Pin 5 not connected or 0V
Signal in the gap Signal on the label
Signal on the label Signal in the gap
Switching outputs pin 2 + pin 4
Operating voltage U

Mounting
For optimum function of the capacitive forked sensor, the sensor should be mounted on a metallic machine part. A lock washer (e.g DIN 6797) should be placed under the screw head to secure the sensor.

Remarks
Operate in accordance with
intended use!
This product is not a safety sensor
and is not intended as personnel
protection.
The product may only be put into
operation by competent persons.
Only use the product in accor-
dance with the intended use.
Base setting
- Set sensitivity to max. (turn
potentiometer to the right),
then turn back 1/2 turn to
the left.
- Base adjustment without
bel tape such that both
LEDs are equally bright.
- If necessary, reduce the
sensitivity setting (in steps
of 1/4 turn to the left).
Base adjustment
Perform after new mounting,
cleaning, sensitivity increase.
Switching behavior
A signal change at the
switching output occurs
when a label enters at the
minimum speed. The output
signal remains constant until
the next edge of an exiting or
entering label is detected.
