Connector Pin. No. Name Description
X1 1 – 3 Mounting These pins are for mounting only.
Leave this pins floating and do not connect them to any potential.
X2 1 GND Ground pin
2 Digital out 0 Digital detection output. Goes to high if the detection algorithm finds a target in front of the sensor.
The detection area and other parameters of the detection algorithm can be easily changed over
the instruction set.
3 VCC Power supply pin (3.2 to 5.5V)
4 RX Serial interface RX input
5 TX Serial interface TX output
6 Digital out 1 Digital miscellaneous output 1. The function is programmable over the instruction set.
This output is only valid together with a high on pin 2 except if it is configured as micro detecti-
on output.
7 Digital out 2 Digital miscellaneous output 2. The function is programmable over the instruction set.
This output is only valid together with a high on pin 2 except if it is configured as micro detecti-
on output.
8 Digital out 3 Digital miscellaneous output 3. The function is programmable over the instruction set.
This output is only valid together with a high on pin 2 except if it is configured as micro detecti-
on output.
