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 movement

This output is only valid together with a

high on pin 2 (valid detection) except if it

is configured as micro detection output.
