Pin No. Name Description
1 GND Ground pin
2 Detect Out Digital detection output.
Signalsa valid detection.
Low " no detection
High " valid detection
3 VCC Power supply pin (3.2 to 5.5V)
4 RX Serial interface RX input
5 TX Serial interface TX output
6 Hold Time In Analogue hold time input. Rangefrom0to3V
0V " minimum hold time
3V " maximum hold time
7 Sensitivity In Analogue sensitivity input.
Range from 0 to 3V
0 V " minimum sensitivity
3V " maximum sensitivity
8 Misc. Out Digital miscellaneous output. The function
isprogrammable over the command set with
the parameter S06.
In the factory setting this output signals the
direction ofavalid detection.
Low " backward / receding movement
High " forward / approaching move ment
This output is only valid toge ther with a
high on pin2 (valid detection) except if it
isconfigured as micro detec tion output.
